There was some miss-match in the implementation. This makes it
concistent, though functionally it worked, except the video decoder
output-io-mode getter.
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.
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.
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.
_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.

- 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

ximage metadata can't be transformed or copied, but provide an empty
transformation function instead of NULL to allow unconditional calling
of metas' transform functions.

AudioUnitGetProperty would fail with kParamErr (-50) every time,
simply because size wasn't initialized.
Now it returns zero latency, but at least it doesn't fail.

This fixes wrong mapping for sRGB as in GStreamer sRGB correctly
apply to RGB formats, while in V4L2 it's an alias for sYCC. Also
add support for the new quantization (range), ycbcr_encoding (matrix)
and xfer_func (transfer) enumeration.
This is the latest from media tree. This should enable more development
of the v4l2 elements. This includes new flags requires to fix draining
path in decoder, colorimetry and much more.
The v4l2 device restarts the sequence counter in case of streamoff/streamon,
the GST offset values are supposed to increment strictly monotonic, so
adjust the sequence counter/offset values in case of caps
renegotiation.

In case of v4l2 driver filled offset/sequence values add frame
loss detection (and write a warning message).
Move offset meta data setting and frame loss checking after the
timestamp adjustment code to get proper timestamps for the
warning message.

If propose_allocation() had not been called yet, it was possible that the driver was not asked at all.
In buffer pool: Consider minimum number of buffers requested by driver when setting config.

Allow renegotiation to happen when buffers have returned after an allocation
query. As the allocation query is serialized, all buffers from the pool
should have returned and we can stop it to create a new one for the
new format
