  Hash : 2b637b8e
  Message : Update the sntrup761 creation script and generated code: - 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@
