Nothing using the EVP_PKEY correctly, so we should revert to the EC_KEY
and ECDSA interfaces. Unfortunately, the SSL client certificate library
uses EC_KEY directly, so just having the EVP_PKEY interface doesn't
work.
Remove the EVP_PKEY interface entirely because it just adds complexity
since the EC_KEY path will do the same thing.

We need to add more methods to the keystore engine, so split out RSA so
it doesn't become too unwieldy.
This doesn't affect the size of the symbol table since the default
visibility for this module is "hidden."
