Attempts to decrypt the encrypted application/pkcs7-mime part.
When non-null, session_key should be a null-terminated
string, such as the one returned by get_session_key from a previous
decryption. If the session_key is not valid, decryption will fail.
If result is non-null, then on a successful decrypt operation, it will be updated to point
to a newly-allocated DecryptResult with signature status information as well as a
list of recipients that the part was encrypted to.
