3941eb7dbd audioconvert: Add dithering-threshold property
By default, no dithering is applied if the target bit depth is above 20
bits. This new property allows to apply dithering nonetheless in these
cases.

e119cdee3b audio-quantize: Switch dither PRNG from LCG to xorshift
While this is slightly more expensive (~48% slower per random number) it
does not cause any measurable difference when running through a complete
audio conversion pipeline.

On the other hand its random numbers are of much higher quality and on
spectrograms for 32 bit to 24 bit conversion the difference is clearly
visible.

6bd1f2753a base: audioencoder: Keep serialize event behind buffers
If a serialized event arrives behind a buffer, it should not be send before
it. This fixes the pending event handling so that only early pending events,
the one that arrrived or was generated while the adapter was empty get send
before pushing buffer. All other events are not pushed after.

This issue lead the latency tracer to think our audio encoder did not have any
latency. This was testing with opusenc in a live pipeline.

830d1595b9 VideoInfo, AudioInfo: fix usage with python bindings
* Expose an actual constructor from caps

* Error out in overrides for code that was using the "manual
  allocation" pattern which only worked by chance. Direct
  the script writer to the new_from_caps constructor instead.

554a2a5145 audio-converter: Fix resampling when there's nothing to output
Sometimes we can't output anything because we don't have enough
incoming frames. In that case, the resampler was trying to call
do_quantize() and do_resample() in a loop forever because there would
never be samples to output (so chain->samples would always be NULL).

Fix this by not calling chain->make_func() in a loop -- seems
completely unnecessary since calling it over and over won't change
anything if the make_func() can't output samples.

Also add some checks for the input and / or output being NULL when
doing conversion or quantization. This will happen when we have
nothing to output.

We can't bail early, because we need resampler->samples_avail to be
updated in gst_audio_resampler_resample(), so we must call that and
no-op everything along the way.

5d3009b7f8 audio-resampler: Fix segfault when we can't output any frames
Sometimes the resampler has enough space to store all the incoming
samples without outputting anything. When this happens,
gst_audio_resampler_get_out_frames() returns 0.

In that case, the resampler should consume samples and just return.
Otherwise, we get a segfault when gst_audio_resampler_resample() tries
to resample into a NULL 'out' pointer.

6e79932ad9 meson: List libraries and their corresponding gir definition
Introduces a `libraries` variable that contains all libraries in a
list with the following format:

``` meson
libraries = [
    [pkg_name, {
        'lib': library_object
        'gir': [ {full gir definition in a dict } ]
    ],
    ....
]
```

It therefore refactors the way we build the gir so that we can reuse the
same information to build them against 'gstreamer-full' in gst-build
when linking statically

4d3a200358 audio: Merge simd libs into the main one
Actually extract the .o objects from the convience libraries and put
them into the main one. Without this, they will just be referenced by
the .pc file, but it will be unusable because they are not installed.

43ed0df54c audio: make GST_AUDIO_INFO_IS_UNPOSITIONED return a boolean
Luckily this worked right since the flag we check is the
only flag and its vale is 1, but feels more correct to
actually check for non-zeroness.
