4554ec42da nova: make write-combined unit test more robust
- touch all memory before time measurements, to reduce lazy paging jitter
- diff of 100us between 2 memset runs are now considered a failure (before 10us)
- add refrence measurements of same region size which is not write-combined
- make the output easier parse able of write-combined test

09461c51bd capture_session: capture stop/wakeup protocol
With this change, a client (i.e., display driver) can register
a wakeup signal handler to be notified on the arrival of new data to
capture. The signal is delivered only when the client has stopped
capturing. The client propagates this condition to the server using
the new 'capture_stopped' RPC call.

This change in principle enables a display driver to suspend its
periodic mode of operation after a few frames without capturing any
new data. As the first driver, the fb_sdl driver has been adapted to
the new protocol. This change not only eliminates the driver's CPU
load when idle, it also reduces the latency of sporadic output
because the response to such GUI updates is no longer bound by a
fixed periodic interval.

2d3c2fc258 fb_sdl: move SDL event loop to dedicated thread
This patch is a preparatory step for relaxing the strictly periodic
operation of fb_sdl. With the new design, the SDL event loop can block
for events while Genode's main entrypoint stays receptive for I/O.
The main entrypoint can interact with the SDL thread by injecting
SDL user events.

The patch also replaces the full-screen clearing and update of the
SDL window by an update of the captured bounding box only. This reduces
the CPU load of fb_sdl when idle. When updating a small part of the
screen (e.g., when moving the mouse only), the load is still rather
heavy though.

6d68d3297d capture_session: propagate physical size in mm
This patch adds the physical screen size as argument to the
Capture::Session::buffer RPC function, which allows drivers to
propagate DPI information to the GUI server. While changing the
the interface, the patch replaces the former use of C++ exceptions
by a result type. The 'Buffer_result' is handled transparently by the
Capture::Connection. The client.h code is now integrated in
connection.h.

d4e4b8bf60 driver/wifi: rework CTRL interface manager
This commit streamlines the interaction between the Wifi::Manager
and the wpa_supplicant's CTRL interface.

As user-facing changes it alters some default settings and introduces
new features:

* Every configured network now needs to explicitly have its
  'auto_connect' (to be considered an option for joining) attribute
  set to 'true' whereas this was previously the default value if the
  attribute was not set at all.

* The 'log_level' attribute is added and configures the supplicant's
  verbosity. Valid values correspond to levels used by the supplicant
  and are as follows 'excessive', 'msgdump', 'debug', 'info', 'warning'
  and 'error'. The default value is 'error' and configures the least
  amount of verbosity.

* The 'bgscan' attribute may be used to configure the way the
  supplicant performs background-scanning to steer or rather optimize
  roaming decision within the same network. The default value is set
  to 'simple:30:-70:600'. It can be disabled by specifying an empty
  value, e.g. 'bgscan=""'.

* The 'verbose_state' attribute was removed alltogether and similar
  functionality is now coverted by 'verbose' attribute.

Implementation-wise the internals changed significantly and are
outlined in the following paragraphs.

Formerly the interaction between the manager and the supplicant
was handled in an apparent way where the internal state of each
interaction was in plain sight. This made the flow cumbersome to
follow and therefor each interaction is now confined to its own
'Action' object that encapsulates the ping-pong of commands and
responses between the manager and the supplicant. All actions are
processed in an sequential way and thus there is no longer any
need to defer pending actions depending on the interal state of
the current interaction. Configuration changes as well as events
issued by the supplicant where new actions can be created are
handled in this fashion. Of note are both signal-handlers,
'_handle_cmds' and '_handle_events' respectively.

The state report, which provides the information about the current
state of connectivity to a given wireless network, was dealt with
in the same vein and its handling was spread across the manager
implementation. Again, to make it easier to follow, the generation
of the state report is now purely driven by the 'Join_state' object.
This object encapsulates the state of connectivity and is normally
updated by events issued from the supplicant (see '_handle_events').
It is also incorporated when handling command responses (see
'_handle_cmds').

Handling of timed-actions, like scan and signal quality
update requests, was done by setting a timeout at the Timer session
directly and thus only one timed-action could be pending at any time.
This excluded dealing with timed-actions like connected-scanning
and signal quality polling concurrently. This was changed and now
a One_shot_timeout is used to programm each concurrent timed-action.

For implementing the communication channel for the CTRL interface the
manager and supplicant use a shared memory buffer, the Msg_buffer.
Since the CTRL interface for Genode was implemented using C, some
shenanigans were performed to access the memory buffer. Now the
CTRL interface implementation uses C++ and only exports the functions
required by the supplicant as C. This simplifies the usage of the
Msg_buffer and allows for removing the global functions needed for
synchronizing the Msg_buffer access as those are now part of the
object itself via the 'Notify_interface'.

42dae6e570 lib/wifi: make errno conversion function public
The 'convert_errno_from_linux' function was already used internally to

It will now also be used to convert the error values included in

ones.

a9b2d9bdc6 gui_session: adjust session quota for wm scenarios
The current default session RAM quota of 36 KiB reflects the needs of
the nitpicker GUI server. However, in most commonly used scenarios, a
GUI client connects to nitpicker indirectly via the wm. The low value
worked so far because the wm did not account RAM and cap usage per
client so far but paid out of its own pocket and faithfully forwarded
all resource upgrades to nitpicker.

When adding resource accounting to the wm, the old default value has the
effect that a new client has to repeatedly attempt the session creation -
each time offering sligthly more session quota - until both nitpicker and
the wm are satisfied.

By roughly doubling the default to 80 KiB, a wm client immediately
succeeds with opening a GUI session without repeated attempts.
By specifying a custom 'cap_quota' amount to the 'Genode::Connection',
the Gui::Connection now donates enough caps for both the wm and
nitpicker.

034de3b1b1 base/connection.h: allow customized cap-quota arg
By default, a 'Connection' donates an amount of caps as declared in
SESSION_TYPE::CAP_QUOTA to the server at session-creation time.

In some situations, however, a client may deliberately want to donate a
larger amount. For example, when opening a GUI session at the wm, the
total amount of needed caps is the sum of those consumed by the wm plus
those consumed by nitpicker. Using this knowledge, the Gui::Connection
may specify a sufficient amount to avoid iterative session-creation
retries. The new 'Connection' constructor accommodates this use case by
accepting an explicit 'cap_quota' argument.

e8e499ae9e nitpicker: account input and framebuffer caps
This patch deduces the caps needed for the framebuffer and input RPC
objects from the resources accounted locally within the session. It also
takes precautions for the situation where a client offers too little
resources, prompting the mid-way cancelling of the 'Session_component'
creation. With the patch, the 'ep.manage' operations are rolled back
by the corresponding 'ep.dissolve' operations.

dd13a976af wm: alloc real view IDs locally
Don't use client-provided view IDs as IDs for the wrapped nitpicker
views. There is no 1:1 relation of IDs and physical views. So if a wm
client re-uses an ID, the physical view is expected to stay in tact.
If the corresponding view object within the wm is not destroyed, however,
its ID remains allocated, which may then conflict the ID of a new view
if the ID is reused by the client. This scenario resulted in the
following error:

  Error: Uncaught exception of type 'Genode::Id_space<Gui::View_ref>::Conflicting_id'

This patch handles the situation by keeping the allocator of physical
views (_real_view) decoupled from the client's ID allocator.
