85afad72ec audio-converter: small API tweaks 
Pass flags in _converter_new() so that we can configure ourselves
differently depending on some options.
SOURCE_WRITABLE -> IN_WRITABLE because the array is called 'in'

980163457e audio-convert: simplify API 
Simplify the API, we don't need the consumed and produced output
arguments. The caller needs to use the _get_in_frames/get_out_frames API
to check how much input is needed and how much output will be produced.

eb09889176 audioconvert: Pass pointer arrays instead of singleton pointers to gst_audio_converter_samples() 
In this specific case it wouldn't cause problems as we only ever access the
first array element, but let's make explicit what is happening here.

CID 1346530 and 1346529

f5a3f70571 audio: adapt API for non-interleaved formats

quantizer functions to support non-interleaved formats.

5e55968546 audio-convert: improve converter API 
Improve the converter API to allow for an max input and output number of
samples and return the number of consumed/produced samples.

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.

1635bc0a45 audioconvert: cleanups and add some docs 
Add docs for the internal audioconvert object before moving it to the
audio library.
Remove get_sizes and implement the trivial logic in the element.

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bcb8068e27 docs: remove outdated and pointless 'Last reviewed' lines from docs 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.

c286f8ffa2 audioconvert: Prefer output formats with the same depth or at least a higher depth

possible. Also ignore GST_AUDIO_FORMAT_FLAG_UNPACK when checking
equality on the flags.

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.
