Cleanups/random changes in the stream cipher code:

Remove encrypt, decrypt - replace by cipher() and cipher1()

Remove seek() - not well supported/tested, I want to redo with a new interface
once CTR and OFB modes become stream ciphers.

Rename resync to set_iv()

Remove StreamCipher::IV_LENGTH and add StreamCipher::valid_iv_length() to
allow multiple IV lengths (as for instance Turing allows, as would Salsa20
if XSalsa20 were supported).
