Wrappers for other languages can't access constants defined by C
preprocessor macros, so they must be exposed as functions. This was
already done for the "default" implementation of each operation, but
this commit adds functions for (almost) all of the underlying
primitives.
A few are currently excluded due to problems with the automated script
used to generated this commit. They are:
* crypto_onetimeauth_poly1305
* crypto_generichash_blake2b
* crypto_verify16
* crypto_verify32
They are identical for all implementations of a given primitive and
it's bound to always be the case.
We will eventually pick suitable implementations at run-time, so
these won't make any sense.
Remove implementation names/versions macros as well.
These should be functions, not macros.
