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.

bswap: change ME to NE in macro names

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).
