Jeremy Compostella 5b8987ae46 libpayload: Support unaligned pointer for memcpy, memmove and memcmp
The memcpy(), memmove() and memcmp() functions use word by word
operations regardless of the pointer alignment.  Depending on the
platform, this could lead to a crash.

This patch makes the memcpy(), memmove() or memcmp() operate byte per
byte if they are supplied with unaligned pointers.
