203e13d97d Always include <sys/cdefs.h>.
I made a mistake caught by code review earlier, so let's try to be
safer by default.

This patch also moves all our "forwarding" headers to the guardless
just-include-the-other-thing style that we usually use. (Where we
have a comment explaining where the header comes from, I've kept
that.)

bf4c32df6b Remove swap16/swap32/swap64 header pollution.
This seems to be obsolete BSD stuff, and the only references to it in the
tree are people #undef'ing it.

3cf53d1a78 Fixes for the ARM-specific bswap_16, bswap_32, and bswap_64.
1. Make the feature test work by excluding known-deficient processors, so
we don't have to maintain a complete list of all the processors that support
REV and REV16.

2. Don't abuse 'register' to get an effect similar to GCC's +l constraint,
but which was unnecessarily restrictive.

3. Fix __swap64md so _x isn't clobbered, breaking 64-bit swaps.

4. Make <byteswap.h> (which declars bswap_16 and friends) use <endian.h>
rather than <sys/endian.h>, so we get the machine-dependent implementations.
