Fixes several notable mistakes and missing information
regarding the API documentation (*.rst).
This will allow API stub generators like bpystubgen or
fake-bpy-module to produce more accurate result.

Refactor and improve waveform drawing.
Drawing now can use line strips to draw waveforms instead of only
triangle strips. This makes us able to properly visualize thin waveforms
as they would not be visible before. We now also draw the RMS value of
the waveform.
The waveform drawing is now also properly aligned to the screen pixels
to avoid flickering when transforming the strip.

The duration and start time for audio strips were not correctly read in
audaspace.
Some video files have a "lead in" section of audio that plays before the
video starts playing back. Before this patch, we would play this lead in
audio at the same time as the video started and thus the audio would not
be in sync anymore.
Now the lead in audio is cut off and the duration should be correctly
calculated with this in mind.
If the audio starts after the video, the audio strip is shifted to
account for this, but it will also lead to cut off audio which might not
be wanted. However we don't have a simple way to solve this at this
point.

The issue was that sounds were always faded from 0 volume when they
started and depending on the currently used buffer size, the fading took
longer or shorter.
The solution stores whether the sound has ever been played back and
consequently does not fade when starting to play back.

Issues were:
* Abusing of `WITH_PYTHON_INSTALL_NUMPY` by both Audaspace and
Mantaflow.
- `PYTHON_INSTALL` options only decide whether we copy python (and
some extra modules) in our Blender installation. On linux it
makes much more sense to use global python installation.
- Now we have instead a proper `WITH_PYTHON_NUMPY`
* Bad assumptions regarding path of headers relative to path of python
module.
- In current Debian testing, modules are under `python3.9`
directory, while headers are under `python3` directory.
- Now we properly `find_path` for headers as well, modifying
`find_python_package` to take an optional argument for headers.
Note that the required changes done to `extern` libraries are in
blender-specific files that do not exist upstream.

Porting bug fix from audaspace upstream.
|

Due to some floating point errors the last frame of a VSE audio strip can
cause integer overflow and crash Blender. This overflow was caused by a
cast from `int64_t` to `int` without prior check. The crash is fixed by
keeping the variable as `int64_t` for as long as possible.
