ff6d1a2a25 audio-converter: add output size argument 
Make it possible to have a different number of output samples than input
samples when we, for example, want to add resampling later.

c36ac3ce45 audioconvert: move audio quantize code to libs 
Move the audio quantize code from audioconvert to the audio library.
work on making an audio converter helper function similar to the video
converter.
Fold fastrandom directly into the quantizer, add some ORC code to
optimize this later.

a7789854d5 audio-channels: rename get_default_mask 
Rename _get_default_mask() to _get_fallback_mask() to make it more
clear that the function only provides a fallback if nothing else can be
done. Also clarify this in the documentation.

API: gst_audio_channel_get_fallback_mask()

010e35afa7 audioconvert: Also copy metas if their API has no tags attached to it 
This is the default basetransform behaviour, being more strict than that
is not really useful.

69f66aff9e Rename property enums from ARG_ to PROP_

bcb8068e27 docs: remove outdated and pointless 'Last reviewed' lines from docs 
They are very confusing for people, and more often than not
also just not very accurate. Seeing 'last reviewed: 2005' in
your docs is not very confidence-inspiring. Let's just remove
those comments.

f317061b9c audioconvert: simplify fixate_format function some more 
If we have no output format yet, any format will do. The
!out_info condition existed in every path, so just split
it our for clarity. KISS.

9e6021fe4b audioconvert: Always prefer the input format if possible 
Previously we could've chosen another format with the same
depth even if the input format was possible.

Also make sure to chose according to the order in the
caps.

dae848818d audio: rework audio caps. 
Rework the audio caps similar to the video caps. Remove
width/depth/endianness/signed fields and replace with a simple string
format and media type audio/x-raw.
Create a GstAudioInfo and some helper methods to parse caps.
Remove duplicate code from the ringbuffer and replace with audio info.
Use AudioInfo in the base audio filter class.
Port elements to new API.

d590bce5f7 audioconvert: Optimize transform_caps() 
If the second and next caps structures are a subset of the already existing
transformed caps we can safely skip them because we would transform them to
the same caps again.

This makes gst_pad_get_caps() on an audiotestsrc ! audioconvert !
audioconvert ! audioconvert ! fakesink pipeline about 1.7 times faster.

f514be993c audioconvert: cleanup helper code 
make_lossless_changes() returns the same structure that we're passing (probably
to enable chaining). Instead of reusing s and making it point to s2 as well,
keep using s2. Drop the assignment which in the 2nd case is a dead one anyway.
