For block and stream ciphers, don't set the size of the key vectors
until we are actually setting a key. This avoids the problem of
prototype objects consuming not just memory but the precious few bytes
of mlock'able memory that we're given by Linux.
Use clear_mem instead of a loop in BigInt::mask_bits
If OS2ECP encounters an invalid format type, include what type it was
in the exception message.
