Allow use of the POP3 APOP authentication command.

Note that this command requires that SASL is compiled with APOP support,
that the plaintext passwords are available in a SASL auxprop backend (e.g.,
sasldb), and that the system can provide enough entropy (e.g., from
/dev/urandom) to create a challenge in the banner.
