Tackle the endian.h mess. Make it so that:
* you can #include <sys/endian.h> instead of <machine/endian.h>,
and ditto <endian.h> (fixes code that pulls in <sys/endian.h> first)

* those will always export the symbols that POSIX specified for
<endian.h>, including the new {be,le}{16,32,64}toh() set. c.f.

if __BSD_VISIBLE then you also get the symbols that our <machine/endian.h>
currently exports (ntohs, NTOHS, dlg's bemtoh*, etc)

* when doing POSIX compiles (not __BSD_VISIBLE), then <netinet/in.h> and
<arpa/inet.h> will *stop* exporting the extra symbols like BYTE_ORDER
and betoh*

guenther spotted my bad copy and pasting.

fall back to htobe64 for htobem64 instead of htole64 on LE archs.

provide an MI api for doing byteswapping loads and stores. some
archs have instrutions that can do this, and the rest that dont get
to use wrappers around the byteswap(3) api.

provide an MI api for doing byteswapping loads and stores. some
archs have instrutions that can do this, and the rest that dont get
to use wrappers around the byteswap(3) api.

this provides MI backends for sparc64 and powerpc which get a big
benefit from this because byteswapping in registers is really hard
for them.

the intended use case is for reading and writing bits of dma memory
handed to and from hardware.

Include <sys/_types.h> to make this header a little bit more self-contained.

When converting endian to same-endian, the macros should cast to unsigned
so that signedness of the input is suppressed.

Adapt things to use __type_t instead of _BSD_TYPE_T_
Add new sys/_types.h header
Include machine/_types.h or sys/_types.h where applicable

Add a __statement macro to use with gcc statement expressions instead
of using __extension__ directly. This lets us define away the whole
thing when lint is in use.

First step in include files overhaul. Use __FOO_VISIBLE (as defined
in sys/cdefs.h) instead of _FOO_SOURCE. Also fix several namespace
pollution issues, including the byte order defines. OK deraad

New endian.h design. All architectures now use a common file for the bulk
part. Some ports can optimize the swap operations. This also means the
general API is extended with swap16, swap32, htobe1
