a2ad5c06ab Adjust run-script RAM quotas to actual demands
With the current implementation resource requests are not automically
satisfied with slack quota by init. Therefore, this commit adapts RAM
quotas of autopilot scenarios to the actual demands.

8ab0a5c795 nic_router.run: avoid use of 'string cat'
It seems that our buildbot has a problem with the TCL command 'string
cat'. In most cases it is not necessary anyway as we can use the ""
enclosure instead. It unfolds inline procedure calls and variables
automatically. We don't want to use "" only in cases where the literal
shall contain many " characters itself as it is the case for XML
configs. Then we use the 'append' command and a helper variable instead.

This commit includes changes to the Nic::Session_component interface.

eab477370f libc: select support for components
Libc components cannot use regular calls to select() as this may suspend
their execution. In this case incoming RPCs will be deferred until
select() returns and the component returns to the entrypoint dispatch
loop. The Libc::Signal_handler solves this problem with a its select()
that either returns the currently ready file descriptors immediately or
calls the registered handler function during libc resume.

3a65f0bba3 libc: 'with_libc' mechanism to enter libc runtime
This commit extends an easy-to-use mechanism to allow Genode component
code to enter/leave the libc application context. This is needed
whenever low-level component code (like signal handlers or RPC
functions) need to interact with potentially blocking libc I/O
functions.

Please note that this commit contains the API-level design only. The
actual context switching code 'execute_in_application_context' is
missing.

c0d61858c3 Support for suspendable read in VFS and libC
The support has two parts. First, a VFS plugin now gets passed an
I/O-response handler callback on construction, which informs users of the
VFS that an I/O event occurred. This enables, for example, the libC to
check if blocking read can be completed. Further, the VFS file I/O
interface provides now functions for suspendable reads, i.e.,
queue_read() and complete_read().

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.

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)

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'.
