75af07495a Revert addition of '#undef av_always_inline' to config.h in the small case. 
Instead, #include config.h at the top of common.h so that av_always_inline
does not get doubly defined.

4b2be143cd Do not throw compiler error if asm code needs alignment, but we do not know 
how to do it for this compiler. This removes a dependency of config.h on the

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).

9f5ff83f2a PPC asm for AV_RL*() 
PPC is normally big endian but has special little endian load/store
instructions.  Using these avoids a separate byteswap.  This makes the
vorbis decoder about 5% faster.  Not much else uses little-endian
read/write extensively.

GCC generates horrible PPC code for the default AV_[RW]B64 (which uses
a packed struct), so we override it with a plain pointer cast.

3c55ce039d ARM asm for AV_RN*() 
ARMv6 and later support unaligned loads and stores for single
word/halfword but not double/multiple.  GCC is ignorant of this and
will always use bytewise accesses for unaligned data.  Casting to an
int32_t pointer is dangerous since a load/store double or multiple
instruction might be used (this happens with some code in FFmpeg).
Implementing the AV_[RW]* macros with inline asm using only supported
instructions gives fast and safe unaligned accesses.  ARM RVCT does
the right thing with generic code.

This gives an overall speedup of up to 10%.
