b2f5899ec2 avcodec/utvideo: Split UTvideoContext into decoder and encoder contexts
In particular the encoder used only a small part of the context:
The new encoder context is only 128B here. It used to be 32992.

0cfc7418bb avcodec/ffv1dec: Fix data races emanating from copying whole context
When using frame threading, the FFV1 decoder's update_thread_context()
function copies the whole context and afterwards restores some allocated
fields with backups made earlier. Among these fields are the
ThreadFrames and the source context's ThreadFrames can change
concurrently without any synchronization, leading to data races which
are undefined behaviour even if they don't lead to problems in
practice (as the destination's own ThreadFrames are restored directly
thereafter).

Fix this by only copying the actually needed fields.

2cb2465cc7 avdevice/lavfi: Fix double-free on error
After the AVFrame has been wrapped into a buffer,
it is owned by the buffer and must not be freed manually
any more. Yet this happens on subsequent errors.

This bug was introduced in 6ca43a9675.

00ba78cd6f avcodec/snow: Move decoder parts out of ff_snow_common_init_after_header
They are not common.

Furthermore, this file is pulled in when linking checkasm and
up until now, the calls to ff_get_buffer() and av_codec_is_decoder()
caused all of libavcodec to be pulled in as well. Besides being
bad size-wise this also has the downside that it pulls in
avpriv_(cga|vga16)_font from libavutil which are marked as
being imported from another library when building libavcodec
as a DLL; this breaks checkasm because it links both lavc and lavu
statically.

418332e01c avcodec/snow: Split ff_snow_get_buffer()
The part of said function that is common to both encoder and decoder
is negligible since c954cf1e1b
and more than offset by the costs of "Am I an encoder?" checks.

So move allocating the frames to the encoder and decoder directly.
Also rename ff_snow_frame_start() to ff_snow_frames_prepare(),
because a frame without a buffer has not been properly started.

97cd698ee4 avfilter/bwdifdsp: Avoid including ff_bwdif_filter_line3_c()
This function is used by the AARCH64 code to filter a few
remaining lines in case the dimensions are not suitably
aligned; it is furthermore also used by checkasm to actually
test the AARCH64 code against. But it is normally not used
and this patch therefore moves it in bwdifdsp.h as a static
inline function so that it can be avoided if possible
or inlined where necessary.
