Pauli ee2993abd0 Deprecate the low level RC2 functions
Use of the low level RC2 functions has been informally discouraged for a
long time. We now formally deprecate them.

Applications should instead use the EVP APIs, e.g. EVP_EncryptInit_ex,
EVP_EncryptUpdate, EVP_EncryptFinal_ex, and the equivalently named decrypt
functions.
