This patch changes the way of how the client-selected sub directory is
communicated to the server. The former opaque session argument is now
passed as last label element, which allows for the flexible tweaking
of this argument by init's session-routing and label-rewriting
mechansims. In particular, it alleviates the need for creating chroot
component instances.
This change requires the following four adaptations at the
configuration level:
- Each file-system session request must now carry a path starting
with / as last session arguments. Hence, <vfs> <fs> nodes that
feature a 'label' attributes must extend the attribute value
with " -> /". For <fs> nodes with no label attribute, "/" is
used as last label argument by default.
- For matching session-routing rules at init's configuration,
the matching of full labels should be replaced by 'label_prefix'
matches, excluding the last (path) argument.
- Wherever a label of a file-system session is rewritten by using
init's 'label' attribute of a <parent> or <child> target node,
the new attribute 'identity' should be used instead. This replaces
the identity part of the label while preserving the client's
directory argument.
- Analogously to the matching of session-routing rules, server-side
policy-selection rules that formerly matched a concrete 'label'
must be changed to match a 'label_prefix' instead.
As a good practice, 'label_prefix' values should end with " ->" if
possible, which clearly delimits the identity part of the label
used by the matching.

This patch changes the window-layout format to support the rectangular
clipping of windows at screen boundaries. The new <boundary> node defines
the clipping boundary for the windows listed within the node. Boundaries
are expected to be disjoint. In the example below, the "vbox" window is
placed partially outside the screen area of "screen_2".
<window_layout>
<boundary name="screen_1" xpos="0" ypos="0" width="640" height="480">
<window id="1" title="launchpad" xpos="10" ypos="140" width="400" height=">
</boundary>
<boundary name="screen_2" xpos="640" ypos="0" width="800" height="600">
<window id="2" title="vbox" xpos="520" ypos="52" width="800" height="600">
<window id="3" title="terminal" xpos="650" ypos="72" width="500" height="400">
</boundary>
</window_layout>
The layouter uses boundaries to restrict the visiblilty of windows to
their respective target areas.
Until now, Sculpt relied on the fact that the window-layout ROM had the
same structure as the resize-request ROM. With the addition of the
<boundary> nodes, this is no longer the case. Therefore, the Sculpt
manager generates a dedicated resize-request ROM now.

This exposes makes the dialog API usable for users of Goa. It turns the
former static dialog library to a shared object and accompanied symbols
file, and adds depot recipes for the library and API.
Issue #5409
If the fb driver is configured to use discrete displays, sculpt now
automatically generates a panorama configuration for nitpicker that
shows all displays side by side. The effective nitpicker config is
now located at config/managed/nitpicker.
The automatism takes effect only when nitpicker's <capture> node
in config/nitpicker is empty. Hence, the managed panorama can be
overridden by a manually managed panorama.
Issue #5286
Increase the RAM quota of the top-level nitpicker instance to support
the flicker-free resizing of large buffers, e.g., when changing screen
resolutions. Otherwise, nitpicker warns as follows:
[init -> nitpicker] Warning: Gui (runtime -> wm -> wm -> decorator)
not enough RAM to preserve buffer content during resize

Instead of publishing the old audio mixer, refer to the recent
record_play_mixer providing the audio API that is used by almost
all components now.

This patch implements the following policy for applications requesting
exclusive input (relative motion): The pointer is grabbed as soon as the
user clicks inside the application window. It is forcibly ungrabbed on
any window-focus change or when tapping the KEY_SCREEN. An application
can always enable (transient) exclusive input during a key sequence,
e.g., when dragging the mouse while holding the mouse button. Transient
exclusive input is revoked when releasing the last button/key.
Fixes#5355
With this patch, the wm accounts RAM and caps consumed on behalf of its
clients to the respective client's session quota instead of paying out
of its own pocket. This should make the wm resilient against resource
exhaustion and lowers the quota requirements.

This patch enables basic use cases of the POSIX 'alarm' function, which
schedules the delivery of a SIGALRM signal after a specified amount of
seconds.

The original use cases of the loader have long been covered by the
dynamic init. The only substantial client of the loader remained to be
the qpluginwidget. However, the qpluginwidget was supported only by the
Arora web browser. But the blending of plugins with websites ultimately
remained a tech demo, and Arora has been replaced by Falkon.

- no need to explicitly switch off vga anymore
- use vPID for VMs which improves TLB usage if multiple vCPUs on same
pCPU is used, which happens to happen on Sculpt.
- support for mwait by nova kernel, which is off by default

- Avoid geometry animation at boot time
- Assign CPU quantum to higher prioritized GUI components
- Defer touch_keyboard start to reduce boot time
Issue #5174
During audio and video playback at a high rate by a VMM, nitpicker on the
boot CPU may interfere with the mixer clients, letting them not finish the
schedule RPC at the mixer in time. Moving nitpicker to the same CPU as
leitzentral mitigates the effect at moment.

The version in ui_report and ui_config were merely used for making test output
more readable. However, there are other ways to achieve this goal.
Ref #5190
* adds rekeying and resizing controls to config+report api of file vault
* moves common types of file vault to file_vault/include/file_vault/types.h
to be included by other components
* fixes wrong type of nr_of_clients fields in file_vault
* introduces the file_vault_gui component that is a minimal graphical front end
for the file vault based on the dialog lib and that uses the
config+report api of the file vault as back end

This commit adds missing routes to I2c for the framebuffer driver of the
MNT Reform. If build for this concrete board the Board_info::Soc variable
within the sculpt_manager is initialized according to the properties of
this device. The `update_soc` routine is called in the initialization of
the sculpt_manager, otherwise it won't be called at all, if no PCI devices
changes are detected. Missing driver binaries and device-tree-binaries are
add to the run-script.

This commits updates the contrib sources to version 8.7.1.
This version requires more random entropy as it queries OpenSSL
about the current random state and will bail if it is not sufficient.
Doubling the content of the '<inline>' VFS plugin as used in static
configurations seems satisfactory.
Furthermore DNS resolving needs a configured '<pipe>' plugin to work
properly.
Fixes#5184.
When the "system" ROM state turns to "suspend",
the S3 state information of the sleep_states ROM are determined and
are used to invoke the privileged Pd::system_control call.

This commit raise various quota to accommodate using a display
resolution of up to '3840x2160' in the static parts, e.g. the
leitzentrale, of Sculpt.
Issue #5174.
Since "sculpt: adjust nitpicker priority", the nitpicker GUI server no
longer runs at the highest priority, yet the runtime_view of the
leitzentrale UI continued to operate at the highest priority.
On slower machines, this results in a visible interference of the CPU-
heavy rendering of the runtime_view with the (now) lower-prioritized
nitpicker, in particular laggy pointer movements.
This commit subordinates the leitzentrale components below the priority
of nitpicker to prevent this interference.
It also simplifies the priority scheme at the static system init: The
timer has the highest priority whereas all other components use the
priority band -1.

The nightly Qemu tests that don't use KVM require more time for completing the
unlock-and-access phase of the test. If the lock phase starts to early, the
file access is interrupted and the output isn't as expected.
Furthermore, on FOC, the cap quota was insufficient.
