2f76476549 lavfi: regroup formats lists in a single structure.
It will allow to refernce it as a whole without clunky macros.

Most of the changes have been automatically made with sed:

sed -i '
  s/-> *in_formats/->incfg.formats/g;
  s/-> *out_formats/->outcfg.formats/g;
  s/-> *in_channel_layouts/->incfg.channel_layouts/g;
  s/-> *out_channel_layouts/->outcfg.channel_layouts/g;
  s/-> *in_samplerates/->incfg.samplerates/g;
  s/-> *out_samplerates/->outcfg.samplerates/g;

c6bc18bc12 vf_hwupload/hwmap: Support setting a fixed pool size
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).

5514bab37a vf_hwmap: Pass mapping mode when deriving frames context on an existing device
To match creation on a newly-derived device.  (This was missed earlier
because the mode is only used in some cases.)

d81be0a60a vf_hwmap: Add reverse mapping for hardware frames
This is something of a hack.  It allocates a new hwframe context for
the target format, then maps it back to the source link and overwrites
the input link hw_frames_ctx so that the previous filter will receive
the frames we want from ff_get_video_buffer().  It may fail if
the previous filter imposes any additional constraints on the frames
it wants to use as output.

124e26971e lavfi: Hardware map filter
Takes a frame associated with a hardware context as input and maps it
to something else (another hardware frame or normal memory) for other
processing.  If the frame to map was originally in the target format
(but mapped to something else), the original frame is output.

Also supports mapping backwards, where only the output has a hardware
context.  The link immediately before will be supplied with mapped
hardware frames which it can write directly into, and this filter
then unmaps them back to the actual hardware frames.
