Merge branch 'master' into common-crypto-backend

* master:
  Use pytest.fixture for backends
  drop to >= 0.8 to make pypy happy
  change to anonymous enum
  require cffi >= 0.8.1
  remove extraneous spaces
  add hmac to commoncrypto binding
  bytes byte back
  add check to confirm we've loaded error strings
  Bind all the PEM errors
  Spelling!
  oops, bytes plz
  don't leak a context in the test
  add tests to the openssl backend to verify that we've registered
  Nonsense I think we need.
  This is a dep
  init the ssl library in the backend
  Actuall install a thing
  Try to run the spellchecker on travis
  Use a normal quote here, not sure where the smart quote came from
  Expose ERR_load_SSL_strings
