a9d497b52d Video capture PipeWire: fix thread and lock annotations
There are two threads involved here, the thread that calls the API
functions and the pipwire main loop. Using one race checker for both is
wrong and triggers aborts.

Use a different race checker for all variables that are used by the
pipewire main loop or guarded against concurrent access with the
thread_loop_lock.

In one case, two RTC_CHECK_RUNS_SERIALIZED() checks are needed, so
enhance the macro to generate unique variable names.

12c502428d Video capture PipeWire: clear notifier after use and upon destruction
Make sure the notifier is reset when tearing down the camera portal and also when we already called it. Destruction of camera portal will be mostly invoked by an object holding it and serving as an implementation of the notifier interface and in such case we have to make sure it will
not get called at this moment.

8b54e37cac DeviceInfoPipeWire: move include for PipeWireSession out of the header
Moving the header file and definitions for PipeWireSession to the source
file allows DeviceInfoPipeWire to be reimplemented or used in wrappers
without the consumer needing to add PipeWire includes and definitions.

dc4c019c62 Video Capture PipeWire: Implement camera rotation support
Support the Pipewire videotransform meta via the already existing shared
infrastructure. This is needed for mobile devices which often have a 90
degree rotated camera - which is likely the reason there is already
support in the shared code paths.

a717c7ada8 Video Capture PipeWire: Filter out non-camera nodes
This can be helpful in various situations, such as debugging with an
unrestricted Pipewire socket or for downstream projects like
B2G/Capyloon. Additionally it will help once we move from the camera
portal to the more generic device portal.

- capture_checker_: access in callbacks/on the capture thread while

- a Mutex if it is already protected by it

823c70209e In VideoCaptureV4L2 use requested/configured capability
VideoCaptureV4L2 has some members that are set in StartCapture during
configuration of the device, but later accessed both on the capture
thread and on the api thread (same as StartCapture) in
CaptureSettings(), which can be called at any time. This is safe because
they are written only on the api thread when the capture thread is not
running. However, there is no helper class that separates the read and
write modes to allow annotations and static analysis of the thread
access of these members.

This commit allows annotations to be added by making VideoCaptureV4L2
use:
- VideoCaptureImpl::_requestedCapability for storing those members
  requested through StartCapture(), to allow access on the api thread
  through CaptureSettings().
- A new member configured_capability_ to replace those members mentioned
  in the first paragraph above. Writes to it happen only in
  StartCapture() and StopCapture(), while reads happen exclusively on
  the capture thread in between.

56d126074e PipeWire video capture: split portal and PipeWire implementations
Allows to use camera portal separately in implementations where each
implementation needs to be called in different places.

This is targeted for Firefox support, where we need to ask for camera
access in the FF frontend code, otherwise making camera access requests
in the backend WebRTC code might result into presenting portal dialogs
asking for access from the javascript API.

f0be3bee1f Add pipewire/portal video capture support
This makes it possible to access cameras through xdg-desktop-portal and
pipewire.

For pipewire, a shared state is needed between the enumeration and the
creation of camera object. So a new API is needed with a shared options
object that holds the state and can be used to choose which backend to try.

a2d0a2ad99 Ignore v4l2 select() return when stopping capture
With some slightly broken webcams, it's possible that the select()
returns with a timeout or no event. In that case, the v4l2 thread
never returns. To fix this, just check if quit_ is set and exit
unconditionally in that case.

c89fdd716c Refactor the PlatformThread API.
PlatformThread's API is using old style function pointers, causes
casting, is unintuitive and forces artificial call sequences, and
is additionally possible to misuse in release mode.

Fix this by an API face lift:
1. The class is turned into a handle, which can be empty.
2. The only way of getting a non-empty PlatformThread is by calling
SpawnJoinable or SpawnDetached, clearly conveying the semantics to the
code reader.
3. Handles can be Finalized, which works differently for joinable and
detached threads:
  a) Handles for detached threads are simply closed where applicable.
  b) Joinable threads are joined before handles are closed.
4. The destructor finalizes handles. No explicit call is needed.

87f7090fd9 Replace more instances of rtc::RefCountedObject with make_ref_counted.
This is essentially replacing `new rtc::RefCountedObject` with
`rtc::make_ref_counted` in many files. In a couple of places I
made minor tweaks to make things compile such as adding parenthesis
when they were missing.

97c4458c8f PlatformThread: add support for detached threads.
The change introduces support for detachable PlatformThreads, for which
the Stop() call doesn't wait until the thread has finished executing.

The change also introduces rtc::ThreadAttributes that carries priority
and detachability thread attributes. It additionally refactors all
known use to use the new semantics.

3b68aa346a Move some RTC_LOG to RTC_DLOG.
Some locations in the WebRTC codebase RTC_LOG the value of the
__FUNCTION__ macro which probably is useful in debug mode. Moving
these instances to RTC_DLOG saves ~10 KiB on arm64.

5b5de21acc Replace RWLockWrapper --> Mutex in DeviceInfoImpl
Reader-writer locks helps performance only when there are many
concurrent readers, and I would expect that isn't the case for this
class. Using a plain mutex reduces complexity.

b64ecd9960 Check V4L2_CAP_VIDEO_CAPTURE when enumerating capture devices on Linux
The side effect of not filtering on V4L2_CAP_VIDEO_CAPTURE is that
every device is enumerated twice. Because we look up devices by name,
and the device that supports V4L2_CAP_VIDEO_CAPTURE seems to always
appear first in /dev/video, this does not seem to end up with us ever
choosing an inappropriate device. We might get away with just filtering
device names from the list, but if the order of devices ever changed in
/dev/video there could be problems.

9d8eaac4ee Delete unneeded direct includes of common_types.h
And delete corresponding dependencies on :webrtc_common. After this
change, common_types.h is included directly only from code in the
following directories:

api/
api/video/
api/video_codecs/
common_video/libyuv/include/
media/base/
modules/remote_bitrate_estimator/
modules/rtp_rtcp/source/
modules/video_coding/codecs/vp9/

There remains plenty of indirect dependencies on the types declared in
common_types.h, but the fewer direct dependencies should make it
easier to find the proper place for each type.
