Similarly to 'utils', I've moved all the stuff in the crypto build-time library into a source directory of its own, and while I'm at it, split up the monolithic sshauxcrypt.c into its various unrelated parts. This is also an opportunity to remove the annoying 'ssh' prefix from the front of the file names, and give several of them less cryptic names.
