Tidy up some memory copying cruft:
...
bcopy.S is no longer needed
memmove and memcpy were both stacking r0 and unstacking it to keep the return value, so push this down into _memcpy.
rename _memcpy.S to memcpy.S.
memmove.S is now just a placeholder otherwise the make system automagically adds a memmove.c file to libkern.
memmove is just another entry point for memcpy.

Move the bswap functions from libutil to libc (this bups the
...
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.
