What's required and not required to be defined is complicated. Write
tests to enshrine it:
endian.h and sys/endian.h:
[bl]e{16,32,64}toh
hto[bl]e{16,32,64}
byteswap.h:
{__,}bswap_{16,32,64}
sys/endian.h:
{__,}bswap{16,32,64}
_BYTE_ORDER
_BIG_ENDIAN
_LITTLE_ENDIAN
_PDP_ENDIAN
endian.h:
__BYTE_ORDER
__BIG_ENDIAN
__LITTLE_ENDIAN
__PDP_ENDIAN
__FLOAT_WORD_ORDER
We also ensure that the sys/endian.h conditions hold true when
we include both endian.h and sys/endian.h in either order.
NOT TESTED: deprecated symbols, internal to glibc symbols
