Ganesh Ajjanagadde 1bb7db217d avutil/crc: avoid needless space wastage of hardcoded crc table
There was no reason AFAIK for making AV_CRC_24_IEEE 12. This simply
resulted in wasted space under --enable-hardcoded-tables:
dynamic: 1318672 libavutil/libavutil.so.55
old    : 1330680 libavutil/libavutil.so.55
new    : 1326488 libavutil/libavutil.so.55

Minor version number is bumped, with ifdefry due to API breakage.

Måns Rullgård 2ed6f39944 Replace many includes of libavutil/common.h with what is actually needed
This reduces the number of false dependencies on header files and
speeds up compilation.

Stefano Sabatini 987903826b Globally rename the header inclusion guard names.
Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.'  to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".
