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.

Matching previous commit for H.264.

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.

These may be used by hwaccel decoders when the standard tables are not
otherwise available.  At the same time, clean up that code into an array
so it's a little less repetitive.

Supports both prefix and suffix SEI, decoding all of the common SEI
types and some more obscure ones.  Most of this is tested by the
existing tests in fate.

Fixes the following warning:
libavutil/avsscanf.c: In function 'decfloat':
libavutil/avsscanf.c:354:9: warning: ISO C90 forbids mixed declarations and code [-Wdeclaration-after-statement]
         int bitlim = bits-3*(int)(rp-9);
         ^~~

The header guards were unnecessarily non-standard and the c file
inclusion trick means the files dont't have standard licence
headers.
