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.

Copied and adopted from musl implementation.
 * converted all 'long double' to 'double'
 * removed %m support

method 0 (inflate/deflate) is the only specified in the specification and the only supported

After adding field type management to the common yadif logic, we can
remove the duplicate copy of that logic from bwdif.

The bwdif filter can use common yadif frame management if we track
when a field is the first or last field in a sequence. While this
information is not used by yadif, the added benefit of removing the
duplicated frame management logic makes it worth tracking this state
in the common code.
