Remove unused BUSmemcpy.c
BUSmemcpy.c provides xf86BusToMem and xf86MemToBus, which are are memcpy
wrappers written to avoid glibc's memcpy on Alpha. glibc'c memcpy on
Alpha has improved much since this was written, so it's no longer
needed. Neither function is used inside the xserver, and no module on
my machine uses either as well.

-/****************************************************************************
-
- For Alpha Linux, BusToMem() and MemToBus() can be simply memcpy(), BUT:
- we need to prevent unaligned operations when accessing DENSE space on the BUS,
- as the video memory is mmap'd that way. The below code does this.
-
-NOTE: we could simply use the "memcpy()" from LIBC here, but that, currently, is
- not as fast.
-
-Thanks to Linus Torvalds for contributing this code.

Simplify unaligned access code
All architectures should be able to use the same unaligned access code,
regardless of whether they need special unaligned access instructions.
Let's let gcc do the heavy lifting.
In the case that we're not using a gcc-compatible compiler, use memmove.
The xserver already requires pixman, so include pixman.h for its uint*_t
types.
