This function implements a fast memory copy function. It can deal with arbitrary lengths, with its pointers on arbitrary alignments. It attempts to optimize larger copies with more efficient copies, it uses byte copies for small moves, parts of larger copies, or the entire copy if the source and destination are misaligned with respect to each other.
Arbitrary overlapping copies are not supported.
