Incorrect parsing of these bits meant that we were incorrectly parsing
the VP9 uncompressed bitstream header for some profiles, as the header
is of variable length and format depending on the profile. Amongst
various unintended effects, this caused the width and height from the SS
to be incorrectly parsed and set in the caps.

On macOS, you always get your own 'timeline' for the AudioUnit session, so timestamps start from 0.
On iOS however, AudioUnit seems to give you a 'shared' timeline so timestamps start at a later, non-0 point in time.
Simply offsetting seems to do the trick.
This was causing osxaudiosrc to not output any sound on iOS.

At some point in iOS 17, this call started waiting for the first render callback (io_proc) to finish.
In our case, that callback also takes the ringbuf object lock by calling gst_audio_ring_buffer_set_timestamp(),
which results in a deadlock.

A correctly configured AVAudioSession is needed on iOS to:
- allow the application to capture microphone audio (in some cases)
- avoid playback being silenced in silent mode
Without this, initializing AudioUnit for capture can fail on iOS >=17 (from my testing).
Since AVAudioSession has a lot of settings, in most cases its setup should be handled by the user/app.
However, just to have a basic default scenario covered, let's configure the bare minimum ourselves,
and allow anyone to disable that behaviour by setting configure-session=false on src/sink.

For some frames with decode-only flag, the v4l2 decoder will not
put them in output list. The corresponding decode-only frames will
be still kept in input list, which may cause potential performance
issue when the input list is full. So release the decode-only frames
according to the decode-only flag after they are processed by decoder
driver.

The matrix multiplication makes some assumption about the element
values to simplify the math with fixpoint values. If this is allowed
for the given matrices is now checked first.
Then the debug output for matrix and a comment have been fixed.

If a new fragment is added with a valid duration but no offset then the start
offset is set later based on the end offset of the previous fragment. At that
point the end offset of this fragment can also be calculated and not doing so
would give the next fragment the same start offset.

Allow sample rate, number of channels and bps to change and in that case update
the caps accordingly.
Also move (non-fatal) validity checks and storing of the header values outside
the actual parsing once we actually know that a valid frame is available.
And also don't warn on the last frame with fixed block size blocking strategy
that the block size has changed: the last frame is allowed to be smaller.

While this specific case is also caught when initializing co_chunk, the error
is ignored in various places and calling into the function would lead to out of
bounds reads if the error message doesn't cause the pipeline to be shut down
fast enough.
To avoid this, no matter what, make sure enough offsets are available when
parsing them. While this is potentially slower, the same is already done in the
non-chunks_are_samples case.
Thanks to Antonio Morales for finding and reporting the issue.
