Make __dtoul() actually DTRT. The calling convention was totally wrong, and

the `big' value should be 2^63, not 2^31.

Just use a store/load pair to get the pattern into the FP reg. This eliminates
...
a bunch of cruft and avoids using a v9a instruction.
In addition, eliminate 8 of the fmovda's, which we are not using the result of
anyway.
Net result is that this should be faster in all cases.

Add __msgctl13(), __semctl13(), and __shmctl13() (symbols are __RENAME()'d

Note that __semctl13() doesn't require the extra stub that the old
semctl()/__semctl() did, as the SUSv2 version takes variable arguments,
and thus does not require the extra indirection.

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.
