Richard Levitte 6f4b766315 PROV: add RSA signature implementation
This includes legacy PSS controls to params conversion, and an attempt
to generalise the parameter names when they are suitable for more than
one operation.

Also added crypto/rsa/rsa_aid.c, containing proper AlgorithmIdentifiers
for known RSA+hash function combinations.
