06edc0d52b base: extend PD session with managing_system call
Introduce the managing_system privilege for components like the
platform_driver to allow it to call system management functionality
that is reserved by kernel or special firmware, e.g., ARM Trusted Firmware.

The former RAM resource configuration attribute `constrain_phys`,
which enabled to constrain the region of physical RAM to be used,
gets replaced by the new, broader managing_system configuration
attribute of a `start` node. It gets enforced by the sandbox library.

157f4b1270 pthread: implement condattr setclock
Normally CLOCK_REALTIME is used. However libraries, like glib, want to
use CLOCK_MONOTONIC. To make those users happy add setting the clock.

Note, the pthread_cond implementation uses the POSIX semaphore API
internally that does not have means to set the clock. For this reason,
the private 'sem_set_clock' function is introduced.

Fixes #3846.

556a5c8086 libc: clean up 'clock_gettime' handling
This patch untangles the dependency of VFS operations that need RTC
information from the 'clock_gettime' libc function that must never be
called from the libc kernel context.

- The 'Rtc' class uses the VFS directly for reading the rtc file instead
  of relying on libc functions.

- The 'Rtc' instance has become part of the 'Kernel' instead of
  being construced as a side effect of the first call of
  'clock_gettime'.

- Changed 'Rtc::read' to return a timespec value, which has a higher
  precision than the formerly used time_t value.

- The 'Rtc::read' returns a value with the relative 'current_time'
  already applied. The former handling of subsequent rtc-value
  updates has been rewritten to become more logical.

- The 'Vfs_plugin' no longer calls 'clock_gettime' but the new
  kernel-level 'Current_real_time' interface.

852ab79359 Move atexit handling from base lib to libc
This patch untangles the interplay of the base library and the libc
during the exit handling.

- The CXA ABI for the atexit handling is now provided by the libc.
  For plain Genode components without libc dependency, __cxa_atexit
  is a no-op, which is consistent with Genode's notion of components.

- The 'abort' implementation of the base library no longer calls
  'genode_exit' but merely 'sleep_forever'. This way, the cxx library
  no longer depends on a 'genode_exit' implementation.

- The libc provides 'atexit' support by storing metadata on the
  libc kernel's heap now, thereby eliminating the former bounded
  maximum number of atexit handlers.

- Shared-library dtors are no longer called via the atexit mechanism
  by explicitly by the dynamic linker. This slightly changes the
  call order of destructors (adjustment of the ldso test). Functions
  marked as destructors are called after the atexit handlers now.

- The libc executes atexit handlers in the application context,
  which supports the I/O operations in those handles, in particular
  the closing of file descriptors.

2e22498e5a nitpicker: no framebuffer and input by default
This patch prevents nitpicker from requesting a framebuffer and input
session by default because the regular use of nitpicker relies on the
capture-session and event-session interfaces by now.

For supporting the nested use of nitpicker via the gui_fb component, it
is still possible to enable the traditional behavior by explicitely
setting the 'request_input' and 'request_framebuffer' config attributes
to "yes".

a89d61acf2 base: call Io_progress_handler only in signal RPC
This remove the call to Io_progress_handler::handle_io_progress() from
wait_and_dispatch_one_io_signal() to prevent unexpected nesting
I/O-progress handling in case of custom dispatch loops (e.g., in libc).
The original intention of Io_progress_handler was to inform the
entrypoint just before blocking in the entrypoint loop.

9662d89cfb Replace input filter with event filter
This commit applies the transition from the "Input" session to the "Event"
session to the event-filtering mechansim. The functionality of the
input_filter is now provided by the event_filter. The event filter
requests only one "Event" session as destination for the filter result,
which is usually routed to the nitpicker GUI server. It provides an
"Event" service to which any number of event sources can connect.

The configuration of the filter chain remains almost the same. Only the
declaration of the <input> nodes is no longer needed. Instead, the
configuration must specify <policy> nodes, which define the mapping of
"Event" clients (event sources) to the inputs used in the filter chain.

The patch adjusts all uses of the nitpicker GUI server accordingly such
that the event filter reports events to nitpicker's event service
instead of having nitpicker request an "Input" session. This dissolves
the dependency of nitpicker from input drivers.

c81af531a3 Turn framebuffer drivers into capture clients
This patch replaces the use of the "Framebuffer" session interface by
the new "Capture" session interface in all framebuffer drivers. Thanks
to this change, those drivers have become mere clients of the nitpicker
GUI server now, and are no longer critical for the liveliness of the GUI
server.

The patch touches the following areas:

- The actual driver components. The new versions of all drivers have
  been tested on the respective hardware. Generally, the drivers
  have become simpler.

- The drivers_interactive packages for various boards. The drivers
  subsystem no longer provides a "Framebuffer" service but needs a
  valid route to the "Capture" service provided by nitpicker.

- The driver manager of Sculpt OS.

- This patch changes the role of the test-framebuffer component from a
  framebuffer client to a capture server so that drivers (capture clients)
  can be directly connected to the test component without the nitpicker
  server.

- Framebuffer driver no longer support the unbuffered mode.

- The fb_bench.run script is no longer very meaningful because it
  interplays solely with nitpicker, not with the driver directly.

- All run scripts for graphical scenarios and the related depot
  archives got adapted to the change.

Until now, Genode's framebuffer session interface was based on the

XRGB where the X part is ignored. It adapts all graphical applications

The patch also adjusts the users of the drivers_interactive packages,
assigning 64 MiB RAM and 1500 caps to the drivers subsystem, which is
sufficient for covering high resolutions at 32 bits per pixel and to
accommodate multi-component USB HID input stacks.

42fddf8390 Cleanup shared-object support mechanics
The former ldso-startup static library (now called ldso_so_support) is
used to spice each shared object/library with local support code for the
dynamic linker (execution of static constructors and ARM-EABI).
Therefore, the library must be statically linked to each dynamic
library.

As a result recipes for dynamic libraries must always depend on the "so"
API, which makes ldso_so_support.mk and so_support.c available
independent of "base". Additionally, ldso_so_support is also provided in
the libc API to cut the dependency early for libc/posix libraries.

accurate capability accounting in core's CPU, TRACE, and RM services.
In particular, the dataspace capabilities needed for core-internal
allocations via the 'Sliced_heap' are accounted to the client now.
The same goes for nitpicker and nic_dump as other former users of the
allocator guard. Hence, the patch also touches code at the client and
server sides related to these services.

The only remaining user of the 'Allocator_guard' is the Intel GPU
driver. As the adaptation of this component would be too invasive
without testing, this patch leaves this component unchanged by keeping a
copy of the 'allocator_guard.h' locally at the component.

4ab990ad5b libc: provide C++ runtime symbols in ABI
This commit puts all C++ runtime/support symbols of ld.lib.so in a
dedicated section of base/lib/symbols/ld and mirrors the section to
libports/lib/symbols/libc. So, the libc ABI resolves potential C++
runtime dependencies of base-ABI-agnostic components at link time. The
runtime resolution is done by the linker by symbol lookup in ld.lib.so.

The libc monitor facility enables the execution of monitor jobs by the

current suspend/resume_all mechanism the main thread iterates over all

conditions by themselves. Threads are only woken up if the completion
condition was met.

cd92b32622 libc: close all open FDs on exit
This is important to issue sync requests for written-to files.

As the closing must be performed by an atexit handler, it happens at a
time _after_ libc plugins are destructed. Consequently an FD allocated
by such a plugin results in a close error, which in turn, does not
destruct the FD. We ultimatedly end up in an infinte loop of
re-attempting the close. For this reason, the patch changes 'close' to
be robust against this special case.

This is generally not a problem because libc plugins are phased out.
However, at present, the libc_noux plugin is still important. With the
changed 'close' in place, there occurred an error message "Error: close:
close not implemented" at the exit of each noux program. This patch
removes the error printing from the libc plugin mechansim to avoid this
noise. The error messages are not important anyway because the
deprecation of the libc plugin interface.

b7fbe65ff2 libc: fork/execve improvements
- Close FDs marked with the close-on-execve flag
  (needed for 'make', which sets the flag for the pipe-in
  FD of forked children)
- Update binary name on execve to use as ROM for subsequent fork
- Enable vfork as an alias for fork (needed by make)
- Purge line buffers for output streams during execve because they
  may be allocated at the allocation heap, which does not survive
  the execve call.
- Consider short-lived processes that may exit while the parent still
  blocks in the fork call.

With these changes, the website generator of genodians.org works without
the need for the Noux runtime.

c51b4b5742 New VFS plugin for emulating POSIX pipes
Add a new plugin for creating pipes between pairs of VFS handles. It is
intended to replace the libc_pipe plugin, one of the last remaining libc
plugins.

In contrast to the libc_pipe plugin, this plugin defers cross-handle
notification until I/O signal handling rather than block and unblock
readers using a semaphore. This is a performance regression in the case
of multiple threads blocking on a pipe, but shall be an intermediate
mechanism pending renovations within the libc VFS and threading layers.
As a side effect, threads blocked on a pipe might not be resumed until
the main thread suspends and dispatches I/O signals.

The "test-libc_pipe" test has been adjusted to use the VFS pipe plugin
and tests both local pipes and pipes hosted remotely in the VFS server.

interface changes) by Norman Feske.

7ac32ea60c libc: support for ioctls via ioctl directory
This patch introduces a new scheme of handling ioctl operations that
maps ioctls to pseudo-file accesses, similar to how the libc maps socket
calls to socket-fs operations.

A device file can be accompanied with a (hidden) directory that is named
after the device file and hosts pseudo files for triggering the various
device operations. For example, for accessing a terminal, the directory
structure looks like this:

  /dev/terminal
  /dev/.terminal/info

The 'info' file contains device information in XML format. The type of
the XML node corresponds to the device type. E.g., If the libc receives
a 'TIOCGWINSZ' ioctl for /dev/terminal, it reads the content of
/dev/.terminal/info to obtain the terminal-size information. In this
case, the 'info' file looks as follows:

  <terminal rows="25" columns="80/>

Following this scheme, VFS plugins can support ioctl operations by
providing an ioctl directory in addition to the actual device file.

Internally, the mechanism uses the 'os/vfs.h' API to access pseudo
files. Hence, we need to propagate the Vfs::Env to 'vfs_plugin.cc' to
create an instance of a 'Directory' for the root for the VFS.

5ab1505d43 file system: enhanced file status info
This patch extends the 'File_system::Status',
'File_system::Directory_entry', and the related 'Vfs' types with
the following additional information:

- Distinction between continuous and transactional files (Node_type)
  (issue #3507)
- Readable, writeable, and executable attributes (Node_rwx),
  replacing the former 'mode' bits
  (issue #3030)

The types 'Node_rwx', 'Node_type' are defined twice,
once for the VFS (vfs/types.h) and once for the 'File_system'
session (file_system_session/file_system_session.h).
Similarly, there is a direct correspondance between
'Vfs::Directory_service::Dirent' and 'File_system::Directory_entry'.

This duplication of types follows the existing pattern of keeping the
VFS and file-system session independent from each other.

648bcd1505 libc: unify use of namespaces
This patch unifies the patterns of using the 'Genode' and 'Libc'
namespaces.

Types defined in the 'internal/' headers reside in the 'Libc'
namespace. The code in the headers does not need to use the
'Libc::' prefix.

Compilation units import the 'Libc' namespace after the definition of
local types. Local types reside in the 'Libc' namespace (and should
eventually move to an 'internal/' header).

Since the 'Libc' namespace imports the 'Genode' namespace, there is
no need to use the 'Genode::' prefix. Consequently, code in the
compilation units rarely need to qualify the 'Genode' or 'Libc'
namespaces.

There are a few cases where the 'Libc', the 'Genode', and the global
(libc) namespaces are ambigious. In these cases, an explicit
clarification is needed:

- 'Genode::Allocator' differs from 'Libc::Allocator'.
- 'Genode::Env' differs from 'Libc::Env'.
- Genode's string functions (strcmp, memcpy, strcpy) conflict
  with the names of the (global) libc functions.
- There exist both 'Genode::uint64_t' and the libc'c 'uint64_t'.

bf92232698 libc: split task.cc into multiple files
This patch is the first step of re-organizing the internal structure of
the libc. The original version involved many direct calls of global
functions (often with side effects) across compilation units, which
made the control flow (e.g., the initialization sequence) hard to
follow.

The new version replaces those ad-hoc interactions with dedicated
interfaces (like suspend.h, resume.h, select.h, current_time.h). The
underlying facilities are provided by the central Libc::Kernel and
selectively propagated to the various compilation units. The latter is
done by a sequence of 'init_*' calls, which eventually will be replaced
by constructor calls.

The addition of new headers increases the chance for name clashes with
existing (public) headers. To disambiguate libc-internal header files
from public headers, this patch moves the former into a new 'internal/'
subdirectory. This makes the include directives easier to follow and the
libc's source-tree structure more tidy.

There are still a few legacies left, which cannot easily be removed
right now (e.g., because noux relies on them). However, the patch moves
those bad apples to legacy.h and legacy.cc, which highlights the
deprecation of those functions.
