OpenSSL 0.9.6g in Debian/unstable stopped working with pgcrypto. This

is pgcrypto bug as it assumed too much about inner workings of OpenSSL.

Following patch stops pgcrypto using EVP* functions for ciphers and lets
it manage ciphers itself.

This patch supports Blowfish, DES and CAST5 algorithms.
