lavfi: Add support for increasing hardware frame pool sizes
Merged-by: Mark Thompson <sw@jkqxz.net>
These filters do not directly know whether the API they are using will
support dynamic frame pools, so this is somewhat tricky. If the user
sets extra_hw_frames, we assume that they are aware of the problem and
set a fixed size based on that. If not, most cases use dynamic sizing
just like they did previously. The hardware-reverse-mapping case for
hwmap previously had a large fixed size (64) here, primarily as a hack
for QSV use - this is removed and extra_hw_frames will need to be set
for QSV to work since it requires fixed-size pools (as the other cases
do, and which didn't work before).
Previously if ff_outlink_frame_wanted() returned 0 it could dereference a null pointer when trying to read nb_samples.

This is done mainly in preparation for the SIMD patches.
- for the 8-bit input, decrease the blend factor precision to 7-bit.
- for the 16-bit input, increase the blend factor precision to 15-bit.
- make sure the blend functions are not called with 0 or maximum blending
factors, because we don't want the signed factor integers to overflow.
Fate test changes are due to different rounding.

Fix the green output issue when use procamp_vaapi without any
arguments, now if use procamp_vaapi without any arguments, will use
the default value to setting procamp_vaapi.

Add ProcAmp(color balance) vaapi video filter, use the option
like -vf "procamp_vaapi=b=10:h=120:c=2.8:s=3.7" to set
brightness/hue/contrast/saturation.

When enabled, text, including effects like shadow or box, will be
completely bound within the video frame.
Default value changed to false to keep continuity of behaviour.
Fixes#6960.

libvidstab introduced this variable only for packed formats but in
vf_vidstab*.c, it's checked for all inputs. So the filter errors out for YUV422/444P streams.

The framerate filter was quite convoluted with some filter_frame /
request_frame logic bugs. It seemed easier to rewrite the whole filter_frame /
request_frame part and also the frame interpolation ratio calculation part in
one step.
Notable changes:
- The filter now only stores 2 frames instead of 3
- filter_frame outputs all the frames it can to be able to handle consecutive
filter_frame calls which previously caused early drops of buffered frames.
- because of this, request_frame is largely simplified and it only outputs
frames on flush. Previously consecuitve request_frame calls could cause the
filter to think it is in flush mode filling its buffer with the same frames
causing a "ghost" effect on the output.
- PTS discontinuities are handled better
- frames with unknown PTS values are now dropped
Fixes ticket #4870.
Probably fixes ticket #5493.
