Does not support PAM_CONV_AGAIN / PAM_INCOMPLETE

[ThomasHabets]

Original issue 276 created by cris.vanpelt on 2013-06-21T13:52:53.000Z:

Asynchronous calls to the libpam-google-authenticator module are not available.

Support for CONV_AGAIN/INCOMPLETE is missing entirely. This makes it more difficult to use the authenticator PAM module for asynchronous authentication. I have attached a small patch which adds this functionality. It may need to be revised for better integration with existing code.
