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.

This can then be used by the pre-commit hook to avoid rebuilding
complete plugin caches to check a change, thus minimizing the potential
diff and making analysis of completely-unrelated cache diffs much less
likely.

Intead of passing around the output of the config generator program,
which consists of paths joined by a separator we can have the generator
simply produce an extra file containing those paths.
This commit only implements the new approach for the core plugins, as
this was needed to avoid spurious meson rebuilds when the pre-commit
hook regenerates the core plugins_cache.

A JSON configuration file is generated for core plugins, which maps
plugin names with sources to parse for docstrings.
The file is then opened by the configuration generator script, which
will now favor explicitly listed files to (usually wildcarded) paths
passed on its command line.

appsink was queuing the caps event both in its GstBaseSinkClass.set_caps()
and its GstBaseSinkClass.sink_event() implementation, but only signaling
new_event from `sink_event`.
This caused `new_event` callbacks to start lagging by one.

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.

Fix-up after commit e56b78417. Unclear how that could
ever have worked. Code only built because basically
everything was disabled due to the missing config.h
include.
- Include config.h so that HAVE_* defines are available.
- Fix missing variable declarations that somehow disappeared
when moving the stats gathering code block into a separate
function in a new file.
- Fix structure variable modified to match name in new function.
