操作 

Second phase of EVP cipher overhaul.

Change functions like EVP_EncryptUpdate() so they now return a
value. These normally have software only implementations
which cannot fail so this was acceptable. However ciphers
can be implemented in hardware and these could return errors.

support added for variable key length ciphers via the
EVP_CIPHER_CTX_set_key_length() function. Other cipher specific
parameters will be added later via the new catchall 'ctrl' function.
New functionality allows removal of S/MIME code RC2 hack. Still needs
support in other library functions, also need to add return codes to
some EVP functions.
New functionality allows removal of S/MIME code RC2 hack.
Still needs support in other library functions, and allow parameter
setting for algorithms like RC2, RC5.
Change lots of functions like EVP_EncryptUpdate() to now return a
value: although software versions of the algorithms cannot fail
any installed hardware versions can.
