CFB support
This requires a bit of explanation. OpenSSL has methods that implement
standard CFB, 1-bit CFB (cfb1), and 8-bit CFB (cfb8). Unfortunately,
while old (read: 0.9.7) versions of OpenSSL appear to test these
variants, newer versions have a comment stating that cfb{1,8} are
unsupported. Accordingly, I've backed out any support for the variants
for now. We can add it back into the CFB class if and when we gain a
backend that supports arbitrary s for 1 <= s <= block_size
