The check of vpx_rac_is_end check(s) are added originally from
1afd246960. It causes a regression
of some vp8 stream. b6b9ac5698 fixes
the regression by a sort of band-aid way. This fixes the wrongness
of the original commit. vpx_rac_is_end() should be called against
the bool decoder for the vp8 headr context, not one for each
coefficient. Reference is vp8_dixie_tokens_process_row() in token.c
in spec 20.16.

This previous expression multiplied a constant (outlink->h) that was
guaranteed to be 0 at this point, thus making it always a no-op.
Fix the calculation, and also properly reset the SAR to 1:1 as is now
necessary (the failure to do so previously hid this bug's existence).
As a result of a typo in the source code, this option was completely
non-functional. In order to fix it, without breaking the current default
behavior, explicitly change this default to 0.
This behavior is also consistent with how other scale filters behave by
default, so it's probably best to enshrine it anyways.
After commit c0b93, it's possible that `ff_vk_filter_config_input` never
gets called, leading to `s->vkctx.input_format` being left unset. This
broke the format auto-selection logic in `libplacebo_config_output`,
resulting in a default to yuv420p, instead of defaulting to the input
format as intended.

x265_sei is available since X265_BUILD 88. Bump required version
to 89 to fix the regression from commit 1f58503013, and remove a
conditional compilation.

svt-av1 v1.2.0 has deprecated vbv_bufsize in favor of using
- maximum_buffer_size_ms (--buf-sz)
- starting_buffer_level_ms (--buf-initial-sz)
- optimal_buffer_level_ms (--buf-optimal-sz)
and vbv_bufsize has not been in use since svt-av1 v0.8.6

compressed_ten_bit_format has been deprecated upstream and has no effect
and can be removed. Plus, technically it was never used in the first place
since it would require the app (ffmpeg) to set it and do additional
processing of the input frames.
Also simplify alloc_buffer by removing calculations relating to the
non-existant processing.

Profile can be derived from values codecpar pixel format only with software
formats. For hardware formats, we're forced to parse a frame header to get
the required information.

Drop the reference to directly committing code, because
- it is highly discouraged and very rarely done these days
- there is no good reason NOT to submit patches for review
Add a link to the development policy chapter.
Frame limiting is now handled using sync queues. This code prevents the
sync queue from triggering EOF, resulting in unnecessarily many frames
being decoded, filtered, and then discarded.

Specificaly, the of_add_attachments() call (which can add attachment
streams to the output) and the check whether the output file contains
any streams. They both logically belong in create_streams().
