When stream time bases are very fine grained (e.g. nanoseconds), 32-bit
segment duration may overflow for even for rather small segment duration
(about 4 seconds long). Therefore we use 64-bit values for segment duration.
Now memcpy is avoided for NAL units that don't contain 0x03 escape
characters.
Improves performance of cbs_h2645_fragment_add_nals from 36940
decicycles to 6364 decicycles based on 8 runs with a 5.1 Mb/s H.264
sample (262144 runs each).

The file name template options now support a new "$ext$" placeholder,
which is replaced with a filename extension specific for the selected
file format. This is useful for the new "auto" format mode, when
different streams may use different file formats, and it is not
possible to specify the correct file name extension exactly.
Resolves warnings in the log about webm segments not having webm extensions.
This commit restores the ability to create DASH streams with codecs
that require different containers that was lost after commit
2efdbf7367. It adds a new "auto" value for
the dash_segment_type option and makes it the default. When in this mode,
the segment format will be chosen based on the codec used in the stream:
webm for Vorbis, Opus, VP8 or VP9, mp4 otherwise.
This commit adds configuration options to libvpxenc.c that can be used to
enable VP8 temporal scalability. It also adds a way to programmatically set the
per-frame encoding flags which can be used to control usage and updates of
reference frames while encoding with temporal scalability enabled.

The current wording regarding size and min_size is completely wrong and
ignores that min_size is indeed only a desired minimal size, not the
actually allocated size.

The SAR of the input could have a numerator or denominator greater than
2^16 which would then be truncated to a 16-bit integer when written to
the VUI parameters, giving a random result. Instead, reduce the SAR to
the nearest representable fraction.
Fixes#7502.
Now the fragment is uninitialized and the input packet freed in case of
errors.
