Now that core functionality is depending on autoconf's AC_C_BIGENDIAN to be

right, there seems precious little reason to have a pile of hand-maintained
endianness definitions in src/include/port/*.h.  Get rid of those, and make
the couple of places that used them depend on WORDS_BIGENDIAN instead.

* BYTE_ORDER NOTE:
*
* Please make sure that your system defines BYTE_ORDER. If your
* architecture is little-endian, make sure it also defines
* LITTLE_ENDIAN and that the two (BYTE_ORDER and LITTLE_ENDIAN) are
* equivilent.
*
* If your system does not define the above, then you can do so by
* hand like this:
*
* #define LITTLE_ENDIAN 1234
* #define BIG_ENDIAN 4321
*
* And for little-endian machines, add:
*
* #define BYTE_ORDER LITTLE_ENDIAN
*
* Or for big-endian machines:
*
* #define BYTE_ORDER BIG_ENDIAN
*
* The FreeBSD machine this was written on defines BYTE_ORDER
* appropriately by including <sys/types.h> (which in turn includes
* <machine/endian.h> where the appropriate definitions are actually
* made).
