Subtitles which contained styled UTF-8 subtitles (i.e. not just 7 bit
ASCII characters) were not handled correctly. The spec mandates that
styling start/end ranges are in "characters". It's not quite clear what
a "character" is supposed to be, but maybe they mean unicode codepoints.

FFmpeg's decoder treated the style ranges as byte idexes, which could
lead to UTF-8 sequences being broken, and the common code dropping the
whole subtitle line.

Change this and count the codepoint instead. This also means that even
if this is somehow wrong, the decoder won't break UTF-8 sequences
anymore. The sample which led me to investigate this now appears to work
correctly.

This is for applications which want to explicitly check for invalid
UTF-8 manually, and take actions that are better than dropping invalid
subtitles silently. (It's pretty much silent because sporadic avcodec
error messages are so common that you can't reasonably display them in a
prominent and meaningful way in a application GUI.)

Enables having proper bit rate values being written into the master
playlist in case of hard-constrained VBR where the maximum bit
rate utilized is known before hand.

Does the same thing as movenc.c, for example.

This reverts commit 7a02b364.

The packet fetched by ff_bsf_get_packet() and ff_bsf_get_packet_ref()
is now guaranteed to be reference counted.

Some bitstream filters may buffer said packet in their own contexts
for latter use. The documentation for av_bsf_send_packet() doesn't
forbid feeding it non-reference counted packets, which depending on
the way said packets were internally buffered by the bsf it may
result in the data described in them becoming invalid or unavailable
at any time.
This was the case with vp9_superframe after commit e1bc3f43, which
was then promptly fixed in 37f4a093 and 7a02b364. It is still the
case even today with vp9_reorder_raw.

With this change the bitstream filters will not have to worry how to
store or consume the packets fed to them.

It's been a noop for years, and it's been argued that in-band headers
should not be forcedly removed without the user's explicit request.

Also, as the FIXME line stated, this is a job for a bitstream filter
like extract_extradata, remove_extradata, dump_extradata, and
filter_units.

Also use that to support mapping VAAPI to Beignet.

The old vaAcquireBufferHandle() API works in fewer cases and provides
less information than the current vaExportSurfaceHandle(), but it exists
on older versions and is already used by the OpenCL code.

Behaves like the existing avgblur filter, except working on OpenCL
hardware frames. Takes exactly the same options.

Matching the previous commit.  This is not applied to the installed header
because it could incorrectly suppress the warning inside user programs.
