Some debuggers/profilers use this metadata to determine which function a
given instruction is in; without it they get can confused by local labels
(if you haven't stripped those). On the other hand, some tools are still
confused even with this metadata. e.g. this fixes `gdb`, but not `perf`.
Currently only implemented for ELF.
This option is only used by mpegvideoenc.
It is a very codec-specific option, so deprecate the global variant.

The openh264 option is dropped altogether since it is just a fallback

Add an allowed value to the private options for frame_skip_cmp which
seems to have been forgotten, but perfectly working.
The libvpx frame dropping feature uses one of such option
(frame_skip_threshold) without the other three. For this reason rename
the option to something more consistent with the other libvpx variables.

The version structure in the main decoder context was not (and
apparently has never been) populated since it was added.
Still, having VC-2 break the existing Dirac Low Delay mode was odd and
easily avoidable had the specifications authors noticed/cared.

The parser scans for "BBCD" to appear in the bitstream which indicate a
parse info header and once that happens, checks if the parse offsets are
sane. Since random BBCD strings might appear in the bitstream the parser
will emit a pointless warning if that happens.
This commit improves parsing by checking for a valid parse code as well
as keeping the original checks for valid parse offsets. The warnings
were removed as they serve no real purpose.

The DSP lacked a function needed to convert signed to unsigned. This was
ignored when originally adding support and templating for bit depths
greater than 8. The 10 bit function was used for 12 bit pictures and
resulted in an improper conversion.

This is needed as near infinite values on the input side result in only some
output to be non finite.
Also it may still be insufficient if subsequent computations overflow

Updates libkvazaar to pass the exact frame rate to Kvazaar by setting

Match the use of AV_PIX_FMT_PAL8 for 1-bit QuickTime Animation in
lavc/qtrle. To reiterate, 1-bit video is not necessary black & white in
QuickTime, merely bi-level. The two colors can be any color. The palette,
either included in the sample description, or the default Macintosh
palette (black & white for 1-bit video) will be set in lavf/qtpalette.
See the QuickTime File Format Specification for details.
