along with this move, made a few api cleanups:

* unified all code that's looking up hashes
  to use new passlib.crypto.lookup_hash() wrapper, which takes
  care of hash name normalization, loading fallback implementations,
  and alg metadata inspection, all hidden behind a memoized function.

* deprecated pbkdf2() in favor of pbkdf2_hmac() -- only real use,
  and new signature matches stdlib function.  additionally,
  this version is a bit faster, due to some assumptions that
  can be made due to the PRF always being HMAC based.

* added compile_hmac() helper which does an even more efficient
  job of pre-compiling a keyed HMAC function; this helped speed up pbkdf2 a bit more.
