extract_unsigned_integer and friends, not SWAP_TARGET_AND_HOST.
	* defs.h, findvar.c: Move SWAP_TARGET_AND_HOST back to findvar.c.
	Rename it to SWAP_FLOATING to make it clear it is no longer for
	integers.

1. These routines only handle byte-swapping, not conversion of
formats. So if host is IEEE floating and target is VAX floating,
