Mans Rullgard 8b19ae0761 crc: fix signed overflow
This fixes a signed overflow from i << 24 when i == 255 by
making i unsigned.  The result of the shift is already
assigned to an variable of unsigned type.

Måns Rullgård e6b22522c9 bswap: change ME to NE in macro names
Other parts of FFmpeg use NE (native endian) rather than ME (machine).
This makes it consistent.

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.

Jeff Downs d468ff0fdf Fix cast of byte buffer to uint32 that was disregarding alignment
requirements.
Now calculates crc byte at a time until aligned, then continues with uint32
optimized calculation.
This fixes crashes during mlp decoding on sparc (at least, maybe others).
