Initial revision
adding environment printing/testing program
continuing merge from jesup, several minor fixes
Fixed bswap_32, bswap_64 (#defines were a little off)
rationalizing header files
made parameter lists match
autoversioning added to documentation
autoconf fixes and minor code cleanup
renaming math.h to eliminate name collision
Add HAVE_INTTYPES_H
unsigned long -> uint32_t
Added inttypes.h
Fixed AC_CHECK_TYPES
unsigned long -> uint32_t
fixed #else's for WORDS_BIGENDIAN
16 -> sizeof(v128_t)
use inttypes.h if available

for no-long-long, extern the functions we'll need.  Define outside of the
tests for os-specific includes
int -> uint32_t
int -> uint32_t (twice)
lo32() -> low32()
restate comparison to avoid 32-bit overflow
lo32() -> low32() (typo)
