Include <sys/endian.h> after defining whether where are little- or big-endian. i386, pc532 and vax still include <machine/byte_swap.h> and define macros for the {n,h}to{h,n}*() functions. mips also defines some endian-independent assembly-code aliases for unaligned memory accesses.

Cleanup and garbage collection; nothing significant. From magnum branch.

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.
