	17	Author : Michael Widenius;
	18	Defines: bmove512()
	19
	20	bmove512(dst, src, len) moves exactly "len" bytes from the source "src"
	21	to the destination "dst". "src" and "dst" must be alligned on long
	22	boundory and len must be a mutliple of 512 byte. If len is not a
	23	multiple of 512 byte len/512*512+1 bytes is copyed.
	24	bmove512 is moustly used to copy IO_BLOCKS. bmove512 should be the
	25	fastest way to move a mutiple of 512 byte.
