a52543acd2 Improve noux fork test (grand child, waitpid)
The test now forks twice - the parent forks a child and the child itself
forks a grand child. Both, parent and child, wait for termination of
their forked process with waitpid(). Additionally, the run script now
checks for exit of the parent (not any noux process).

7386c4e1d1 More robust handling of suspend in entrypoint
First, calls to manage and dissolve signal contexts now check if the
signal receiver was constructed. There is a small window during suspend
where it is destructed before reconstructed again.

Last, we ensure that processing of incoming signal was deblocked by the
suspend signal before entering the suspend operation. This way we ensure
already queued signal are handled.

818795ab90 vfs/block: fix seek-offset handling during write
The block file system wrongly modified the seek offset during a
read-modify-write operation that is required for sub-block-size
requests. This led to problems whenever such write requests spanned
multiple blocks and thereby were handled in multiple iterations.

c65f78671f VFS block test
This test reproduces an issue of the VFS block file system when the
underlying block device has a coarser granularity than the block
requests issued by the VFS client. I.e., if the underlying block device
has a block size of 4K, writing a sequence of (non-4K-aligned) 512 blocks
that crosss a 4K boundary corrupts the data on the block device.

9adc6f1228 os: compile-time-defined parent-service registry
The new utility at 'os/static_parent_services.h' allows the creation of
a registry of parent services at compile time and thereby eliminates the need
for dynamic memory allocations whenever the set of services is known at
compile time as is the case for most uses of 'Slave::Policy'. The commit
showcases the utility in the bomb test.

b4600bfc99 sd_card_bench: exclude foc+imx_53 and odroid_xu
On Odroid XU the SD card driver comes up and finds a card but for card
access it seems that we would need a platform driver like on Arndale.

On imx_53, the first SDHCI MMIO access faults. This is likely due to the
AIPSTZ memory bridge. On HW, we initialize the AIPSTZ in the kernel, but
when I tried doing that in the platform driver instead, the first AIPSTZ
MMIO access faults ^^ So I gave up for now and removed support.

* remove unnecessary multithreading
* model test steps as classes that are independent from each other and managed
  by Main as constructibles
* use references instead of pointers and exceptions instead of error codes
* use Attached_* helpers intead of doing attach/detach manually
* use helpers like String, Id_space, Registry instead of arrays and lists
* make the run script suitable for automated execution and conclusion

e0fef69cb3 test/ram_fs_chunk: fix bug in allocation tracking
In the past, the Genode::destroy, that is called by the RAM-FS-chunk destructors,
issued Allocator::free instead of the C++ delete. Therefore it was possible to
use the size argument of Allocator::free for the allocation tracker in the
RAM-FS-chunk test. Nowadays, we have to keep track of the allocation sizes
ourselves because delete doesn't hand over the size.

ca38375107 test/fb_block_adapter: remove
The FB Block Adapter in os/src/test visualizes a block session via a
Framebuffer session. As far as I can see, it is not a test but rather
the base for a bump-in-the-wire component. However, for this role it
currently lacks a Block back-end. As it also would have to be updated to
use the new base API I removed it instead, leaving only its git
history as inspiration if someone needs such a component in the future.

eccc539651 noux-pkg/less: use LIBS when building tools
lesskey and lessecho missed the declaration of ${LIBS} on the compiler
command line, which ended up in unusable programs.

  > file noux-pkg/less/lesskey.broken

  noux-pkg/less/lesskey: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked, interpreter ld.lib.so, not stripped

The issue was identified because -O0 builds broke with

  ld: lesskey: The first section in the PT_DYNAMIC segment is not the .dynamic section

Unfortunately, this simple fix renders both tools also dependent to libm
and ncurses which they don't use.

02d5efcf3f init: apply routing to environment sessions
The init component used to create the CPU/RAM/PD/ROM sessions (the child
environment) for its children by issuing session requests to its parent,
which is typically core. This policy was hard-wired. This patch enables
the routing of the environment sessions of the children of init
according to the configured routing policy.

Because there is no hard-wired policy regarding the environment sessions
anymore, routes to respective services must be explicitly declared in
the init configuration. For this reason, the patch adjusts several run
scripts in this respect.

This patch removes the outdated '<if-args>' special handling of session
labels. The '<if-args>' feature will eventually be removed completely
(ref #2250)

c1e399025e os: let empty label prefix/suffix match
This patch changes the 'Xml_node_label_score' to regard an empty
label_prefix or label_suffix as a match instead of a conflict. Until
now, there was no use case for an empty label_prefix. But with init's
new ability to route environment sessions, an empty prefix denotes any
child-initiated session (as oposed to an parent-initiated environment
session).

e43da51bd6 base: handle dangling env sessions in ~Child
This commit addresses the situation where an environment session
outlives the session-providing service. In this case, the env session
got already invaidated at the destruction time of the server. However,
the underlying session-state structure continues to exist until the
client is destructed. During the eventual destruction of such a dangling
environment session, we have to be careful not to interact with the
no-longer existing service.

6f6f68f216 nitpicker/wm: fix session_control mechanism
The session-control mechanism is based on the way how sessions are
labeled. In #2171, we changed the labeling to be more strict. In
particular, label-less sessions do no longer exist.

Unfortunately, nitpicker and the window manager still handled the former
weaker labeling, which ultimately led to a situation where any
session-control argument would mismatch. The behavior could be observed
in the launcher.run script where a click on the subsystem button would
not focus the clicked-on subsystem. With the patch, the scenario works
again as expected.

a7f40b24ca Warn about the use of deprecated env() function
This patch enables warnings if one of the deprecate functions that rely
in the implicit use of the global Genode::env() accessor are called.

For the time being, some places within the base framework continue
to rely on the global function while omitting the warning by calling
'env_deprecated' instead of 'env'.

3d7b92ea50 Generalize ABI mechanism to shared objects
This patch make the ABI mechanism available to shared libraries other
than Genode's dynamic linker. It thereby allows us to introduce
intermediate ABIs at the granularity of shared libraries. This is useful
for slow-moving ABIs such as the libc's interface but it will also
become handy for the package management.

To implement the feature, the build system had to be streamlined a bit.
In particular, archive dependencies and shared-lib dependencies are now
handled separately, and the global list of 'SHARED_LIBS' is no more.
Now, the variable with the same name holds the per-target list of shared
libraries used by the target.

4da52517c1 Simpify startup of dynamically linked binaries
This patch removes the component_entry_point library, which used to
proved a hook for the libc to intercept the call of the
'Component::construct' function. The mechansim has several shortcomings
(see the discussion in the associated issue) and was complex. So we
eventually discarded the approach in favor of the explicit handling of
the startup.

A regular Genode component provides a 'Component::construct' function,
which is determined by the dynamic linker via a symbol lookup.
For the time being, the dynamic linker falls back to looking up a 'main'
function if no 'Component::construct' function could be found.

The libc provides an implementation of 'Component::construct', which
sets up the libc's task handling and finally call the function
'Libc::Component::construct' from the context of the appllication task.
This function is expected to be provided by the libc-using application.
Consequently, Genode components that use the libc have to implement the
'Libc::Component::construct' function.

The new 'posix' library provides an implementation of
'Libc::Component::construct' that calls a main function. Hence, POSIX
programs that merely use the POSIX API merely have to add 'posix' to the
'LIBS' declaration in their 'target.mk' file. Their execution starts at
'main'.

253097314c Add unified build directories to create_builddir
This patch makes the benefit of the recently introduced unified Genode
ABI available to developers by enabling the use of multiple kernels from
within a single build directory. The create_builddir tool has gained a
new set of kernel-agnostic platform arguments such as x86_32, or panda.
Most build targets within directories are in principle compatible with
all kernels that support the selected hardware platform. To execute a
scenario via the run tool, one has to select the kernel to use by
setting the 'KERNEL' argument in the build configuration
(etc/build.conf). Alternatively, the 'KERNEL' can be specified as
command-line argument of the Genode build system, e.g.:

  make run/log KERNEL=nova

This allows us to easily switch from one kernel to another without
rebuilding any Genode component except for the very few kernel-specific
ones.

The new version of the 'create_builddir' tool is still compatible with
the old version. The old kernel-specific build directories can still be
created. However, those variants will eventually be removed.

Note that the commit removes the 'ports-foc' repository from the
generated 'build.conf' files. As this is only meaningful for 'foc',
I did not want to include it in the list of regular repositories (as
visible in a 'x86_32' build directory). Hence, the repository must
now be manually added in order to use L4Linux.

0d295f75a1 base: apply routing policy to environment sessions
This patch changes the child-construction procedure to allow the routing
of environment sessions to arbitrary servers, not only to the parent.
In particular, it restores the ability to route the LOG session of the
child to a LOG service provided by a child of init. In principle, it
becomes possible to also route the immediate child's PD, CPU, and RAM
environment sessions in arbitrary ways, which simplifies scenarios that
intercept those sessions, e.g., the CPU sampler.

Note that the latter ability should be used with great caution because
init needs to interact with these sessions to create/destruct the child.
Normally, the sessions are provided by the parent. So init is safe at
all times. If they are routed to a child however, init will naturally
become dependent on this particular child. For the LOG session, this is
actually not a problem because even though the parent creates the LOG
session as part of the child's environment, it never interacts with the
session directly.

c450ddcb3d Disambiguate kernel-specific file names
This patch removes possible ambiguities with respect to the naming of
kernel-dependent binaries and libraries. It also removes the use of
kernel-specific global side effects from the build system. The reach of
kernel-specific peculiarities has thereby become limited to the actual
users of the respective 'syscall-<kernel>' libraries.

Kernel-specific build artifacts are no longer generated at magic places
within the build directory (like okl4's includes, or the L4 build
directories of L4/Fiasco and Fiasco.OC, or the build directories of
various kernels). Instead, such artifacts have been largely moved to the
libcache. E.g., the former '<build-dir>/l4/' build directory for the L4
build system resides at '<build-dir>/var/libcache/syscall-foc/build/'.
This way, the location is unique to the kernel. Note that various tools
are still generated somewhat arbitrarily under '<build-dir>/tool/' as
there is no proper formalism for building host tools yet.

As the result of this work, it has become possible to use a joint Genode
build directory that is usable with all kernels of a given hardware
platform. E.g., on x86_32, one can now seamlessly switch between linux,
nova, sel4, okl4, fiasco, foc, and pistachio without rebuilding any
components except for core, the kernel, the dynamic linker, and the timer
driver. At the current stage, such a build directory must still be
created manually. A change of the 'create_builddir' tool will follow to
make this feature easily available.

This patch also simplifies various 'run/boot_dir' plugins by removing
the option for an externally hosted kernel. This option remained unused
for many years now.

3865ee7ccc foc: move base/thread_state.h to include/foc/
The header is foc-specific. It used to shadow the generic one provided
by the base repository, which contradicts with the kernel-agnostic
Genode API. Hence, it had to be moved to a foc-specific location.

f54c85e045 Genode application binary interface (ABI)
This patch decouples the kernel-specific implementation of the dynamic
linker from its kernel-agnostic binary interface. The name of the
kernel-specific dynamic linker binary now corresponds to the kernel,
e.g., 'ld-linux.lib.so' or 'ld-nova.lib.so'. Applications are no longer
linked directly against a concrete instance of the dynamic linker but
against a shallow stub called 'ld.lib.so'. This stub contains nothing
but the symbols provided by the dynamic linker. It thereby represents
the Genode ABI.

At system-integration time, the kernel-specific run/boot_dir back ends
integrate the matching the kernel-specific variant of the dynamic linker
as 'ld.lib.so' into the boot image.

The ABI symbol file for the dynamic linker is located at
'base/lib/symbols/ld'. It contains the joint ABI of all supported
architectures. The new utility 'tool/abi_symbols' eases the creation of
such an ABI symbol file for a given shared library. Its result should be
manually inspected and edited as needed.

The patch removes the 'syscall' library from 'base_libs.mk' to avoid
polluting the kernel-agnostic ABI with kernel-specific interfaces.

71d30297ff hw: clean up scheduling-readiness syscalls
This cleans up the syscalls that are mainly used to control the
scheduling readiness of a thread. The different use cases and
requirements were somehow mixed together in the previous interface. The
new syscall set is:

1) pause_thread and resume_thread

They don't affect the state of the thread (IPC, signalling, etc.) but
merely decide wether the thread is allowed for scheduling or not, the
so-called pause state. The pause state is orthogonal to the thread state
and masks it when it comes to scheduling. In contrast to the stopped
state, which is described in "stop_thread and restart_thread", the
thread state and the UTCB content of a thread may change while in the
paused state. However, the register state of a thread doesn't change
while paused. The "pause" and "resume" syscalls are both core-restricted
and may target any thread. They are used as back end for the CPU session
calls "pause" and "resume". The "pause/resume" feature is made for
applications like the GDB monitor that transparently want to stop and
continue the execution of a thread no matter what state the thread is
in.

2) stop_thread and restart_thread

The stop syscall can only be used on a thread in the non-blocking
("active") thread state. The thread then switches to the "stopped"
thread state in wich it explicitely waits for a restart. The restart
syscall can only be used on a thread in the "stopped" or the "active"
thread state. The thread then switches back to the "active" thread state
and the syscall returns whether the thread was stopped. Both syscalls
are not core-restricted. "Stop" always targets the calling thread while
"restart" may target any thread in the same PD as the caller. Thread
state and UTCB content of a thread don't change while in the stopped
state. The "stop/restart" feature is used when an active thread wants to
wait for an event that is not known to the kernel. Actually the syscalls
are used when waiting for locks and on thread exit.

3) cancel_thread_blocking

Does cleanly cancel a cancelable blocking thread state (IPC, signalling,
stopped). The thread whose blocking was cancelled goes back to the
"active" thread state. It may receive a syscall return value that
reflects the cancellation. This syscall doesn't affect the pause state
of the thread which means that it may still not get scheduled. The
syscall is core-restricted and may target any thread.

4) yield_thread

Does its best that a thread is scheduled as few as possible in the
current scheduling super-period without touching the thread or pause
state. In the next superperiod, however, the thread is scheduled
"normal" again. The syscall is not core-restricted and always targets
the caller.

4e4cdacab3 base: trim main-thread size to 4/8 KiB
The main thread does no longer execute application code. It is solely
responsible for the initialization of the component's entrypoint and for
retrieving asynchronous notifications. Since the stack usage is no
longer dependent on application-specific code, we can significantly
shrink it to reduce the memory footprint of components. In the worst
case - should the stack overrun - we would observe a page fault because
the stack is placed in the stack area, surrounded by guard pages.

a387d68c2c base: use a default stack size of 64 KiB
This patch replaces the former machine-word-dependent default stack size
by the fixed value of 64 KiB which should suffice for components on both
32 and 64 bit. Previously, the default stack size on 64 bit was 128 KiB,
which is wasteful. If a component needs more stack than 64 KiB, it can
specify a custon stack size by implementing 'Component::stack_size'.

28f5688dcf base: reduce size of initial stack from 32K to 4K
The initial stack is solely used to initialize the Genode environment

is not dimensioned too small, the patch introduces a sanity check right
before switching to the application stack.

5a1cef6381 Make label prefixing more strict
This patch unconditionally applies the labeling of sessions and thereby
removes the most common use case of 'Child_policy::filter_session_args'.
Furthermore, the patch removes an ambiguity of the session labels of
sessions created by the parent of behalf of its child, e.g., the PD
session created as part of 'Child' now has the label "<child-name>"
whereas an unlabeled PD-session request originating from the child
has the label "<child-name> -> ". This way, the routing-policy of
'Child_policy::resolve_session_request' can differentiate both cases.

As a consequence, the stricter labeling must now be considered wherever
a precise label was specified as a key for a session route or a server-
side policy selection. The simplest way to adapt those cases is to use a
'label_prefix' instead of the 'label' attribute. Alternatively, the
'label' attribute may used by appending " -> " (note the whitespace).
