auth-provider: move auth provider logic into each class

Rather than make all of them rely on MMBaseModem for it. This
lets us disentangle dependencies for easier unit testing.

For interfaces, rather than casting directly to MMBaseModem
use intermediate interfaces (MMIfaceAuth and MMIfaceOpLock)
that tests can fake out.
