Comment (by warner):

 I've got a cleaned up branch at
 https://github.com/warner/pycryptopp/tree/42-hkdf . It incorporates all
 these patches (including the .digest_size one), plus some necessary fixes.
 The result almost works: the (only?) remaining problem is that
 pycryptopp's SHA256 objects do not have a {{{.copy()}}} method (unlike
 {{{hashlib.SHA256}}}), and the stdlib HMAC code depends upon one. Not sure
 how to add this, it might need some C++ object-copying that's beyond my
 current comfort level.
