- remove unneeded header files and typedefs and rely on crypto_api.h - add defines to map types used to the crypto_api ones instead of typedefs. This prevents typedef name collisions in -portable. - remove CRYPTO_NAMESPACE entirely instead of making it a no-op - delete unused functions and make the remaining ones that aren't exported static. ok djm@ OpenBSD-Commit-ID: 7b9d0cf3acd5a3c1091da8afe00c904d38cf5783
