Purpose of commit: new feature

Commit summary:
---------------
Added libpammodutil and link it with every module as its built.
The issue here is that there is a lot of code that the various modules
use in common, and this staic library can be used to help make this code
more maintainable. I do not intend to make this library dynamic. Especially
right now, as I want to be free to chop and change the API and don't want
to deal with revision control and third party modules.

This checkin makes the pam_rhost_auth module make some use of this new
library. I don't intend to add support for any other module prior to
releasing 0.76.
