Separate the blocks to make the grouping easier to grasp,
add the file properly to the group and fix the file description
incorrectly used as filename, fixing the following doxy warning:
warning: the name 'Colorspace' supplied as the argument in
the \file statement is not an input file
Make it a bit easier to grasp the grouping when not
unnecessarily splitting comment blocks.
Additionally do not try to add lavu_video_stereo3d to itself, resolving
the following doxy warning:
warning: Refusing to add group lavu_video_stereo3d to itself
Make it a bit easier to grasp the grouping when not
unnecessarily splitting comment blocks.
Additionally do not try to add lavu_video_spherical to itself, resolving
the following doxy warning:
warning: Refusing to add group lavu_video_spherical to itself
Make it a bit easier to grasp the grouping when not
unnecessarily splitting comment blocks.
Additionally do not try to add lavu_video_display to itself, resolving
the following doxy warning:

This is more natural, because said context is only used
for the duration of one call to svq1_encode_frame().

The encoder uses ff_svq1_inter_mean_vlc + 256 and setting
hidden visibility allows to bake this "+ 256" into the
general offset of ff_svq1_inter_mean_vlc and the code
accessing it.
For certain arches, this is also required for the compiler
to not produce overtly pessimistic code that can't be fixed
up by the linker lateron.

Currently, SVQ1EncContext is defined in a header that is also
included by the arch-specific code that initializes the one
and only dsp function that this encoder uses directly.
But the arch-specific functions to set this dsp function
do not need anything from SVQ1EncContext. This commit therefore
adds a small SVQ1EncDSPContext whose only member is said
function pointer and renames svq1enc.h to svq1encdsp.h
to avoid exposing unnecessary internals to these init
functions (and the whole mpegvideo with it).

Bayer sources are read in groups of 2 lines (e.g. for a
BGGR flavor, the first row contains only B and G samples,
while the second row contains only G and R samples). They
need to be read as a whole.

This fixes a regression from commit 36117968ad.
wrapped_url_read() used to be able to return positive number from
ffurl_read(). It relies on the result to check if EOF is reached in
async_buffer_task().
But FIFO callbacks must return 0 on success. This should be handled
in ring_write() instead.
Test case:
ffmpeg -f lavfi -i testsrc -t 1 test.mp4
ffmpeg -i async:test.mp4

This simplifies the code as there is no other place the error buffer
is needed, so the av_err2str helper macro can be used.

av_err2str which is a wrapper for av_strerror already calls
strerror_r if available and if not has a fallback for the other
error codes that would be handled by that, so manually calling
strerror again if it fails is not necessary.

This filter currently keeps the input timebase, but produces CFR output.
It is thus simpler to use 1/output fps as the output timebase.
Also, set output frame durations.
