Implement cipher_auth_{en,de}crypt_ext()

Work in progress: next step is to test it!

Extract the part that is common with non-ext version to a new internal
function. (We can't just use the non-ext version for that, as it's going to be
deprecated.)

Currently the NIST_KW part is somewhat duplicated between the ext
and non-ext versions, but that's OK because it will soon be removed from the
non-ext version.
