7b17615da8 v4l2: Set O_CLOEXEC on the device fd
This is needed to make sure that child processes don't inherit the video
device fd which can cause problems with some drivers.

040467d118 ximagesrc: Gather and coalesce all damaged areas before retrieving.
These days the xserver seems to give us the same damage regions
over and over for entire windows, and we retrieve them multiple
times, which gives time for more damage to appear. Instead, just
quickly gather all damaged areas into a region list and copy
out once.

8f0f976375 osxaudio: Avoid making a duplicate structure in caps for mono/stereo case
For 1ch or 2ch devices, we just need to set the caps to allow both
options since CoreAudio will up/downmix appropriately.

Also fixes the condition for the 2ch case to be exact, rather than at
least 2 channels since the downmix will not take place in the >stereo
case.

691ecebe22 osxaudio: Don't set the format on an initialized AudioUnit
We need to initialize the AudioUnit early to be able to probe the
underlying device, but according to the AudioUnitInitialize() and
AudioUnitUninitialize() documentation, format changes should be done
while the AudioUnit is uninitialized. So we explicitly uninitialize the
AudioUnit during a format change and reinitialize it when we're done.

f107f7306b osxaudio: Fix lockup in _audio_unit_property_listener
_audio_unit_property_listener is called either from a Core Audio thread
or as a result of a Core Audio API (e.g. AudioUnitInitialize)
from our own thread. In the latter case, osxbuf can be already locked
(GStreamer's mutex is not recursive).

We introduce the flag cached_caps_valid and use it instead of nullifying
cached_caps when we cannot lock on osxbuf.

0e5d698c6f osxaudio: Overhaul of probing caps
- Probing caps is unified between source and sink
- Hardware stream format is now reported as preferred capabilities
  (dynamically updated when hardware configuration changes)
- Get hardware channel layout from Remote IO just like from HAL
- More comprehensive mapping between AudioChannelLabel and
  GstAudioChannelPosition
- Support for unpositioned channel layouts
- Announce stereo-mono upmixing/downmixing in caps
