In all cases where the block size of the cipher is fixed, the key

parameters are as well. So make them template paramters.

The sole exception was AES, because you could either initialize AES
with a fixed key length, in which case it would only be that specific
key length, or not, in which case it would support any valid AES key
size. This is removed in this checkin; you have to specifically ask for
AES-128, AES-192, or AES-256, depending on which one you want.

This is probably actually a good thing, because every implementation
other than the base one (SSSE3, AES-NI, OpenSSL) did not support
"AES", only the versions with specific fixed key sizes. So forcing
the user to ask for the one they want ensures they get the ones
that are faster and/or safer.
