New macro ALIGNED_POINTER_LOAD.

To be used with ALIGNED_POINTER(p,t) instead of writing *(const t *)p
directly.  This way, on machines without strict alignment, we can use
memcpy to pacify sanitizers, while getting the same compiled code in
the end with a single (say) MOV instruction.

Fix byte order bug in murmurhash and pacify sanitizers.
add now required includes for memcpy prototypes analogue to other hash functions
(fix the build)
