avutil/crc: Dont limit CRC32 standard tables
...
Currently, standard tables like AV_CRC_32_IEEE and such are being generated (or
provided in case the user compiles with hardcoded tables) with only 257 elements.
We're missing a considerable boost in performance by not making them with a size
of 1024 elements instead.

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.

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).
