lavf/dashdec: Add webm to the list of allowed extensions.
This is in coherence with dashenc, which can now generate segments with
webm file name extension by default. Dashdec should be able to handle
such streams by default as well.

16.48 speedup ratio. On x86, SSE2 is ~7. Curiously, the Power C version
takes as many cycles as the x86 SSE2 version, yikes it's fast.
Note that this function uses VSX instructions, but is not marked so.
This is because several existing functions also make that mistake.
I'll submit a patch moving them once this is reviewed.

The color fields were moved to another struct, and a way to propagate

lavf/dashenc: Fix segment duration overflow on fine time bases.
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.

lavf/dashenc: Add support for format-specific file extensions.
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.

lavf/dashenc: Add DASH segment type auto and make it the default
This commit restores the ability to create DASH streams with codecs
that require different containers that was lost after commit 2efdbf7367989cf9d296c25fa3d2aff8d6e25fdd. 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.
avutil/mem: Correct documentation of av_fast_*alloc(z)
The current wording regarding size and min_size is completely wrong and
