Mostly a cleanup release. Cleanup old code, improve documentation,
improve GCC-cleanness, etc. Disable the crandom output buffer so that it won't return duplicate data across fork(). I should still stir in more entropy into the buffer at least when RDRAND is available, but this should prevent disasters for now. The Elligator code in the current version is incompatible with past versions due to a minor tweak. It wasn't being called by any of the API functions, though. Removing "magic" constants and type names. So for example p448_t is now field_t (though maybe it should really be felem_t?). This should enable other curves with the Goldilocks code in the not-too- distant future. Added CRANDOM_MIGHT_IS_MUST so that you don't have to -D a bunch of things on the command line. You can `make bat` to make an eBAT which probably doesn't work. I haven't implemented the improved nonce generation from the firstname.lastname@example.org thread yet.
