[PATCH] pam authentication

I've made a patch to improve kannel's pam authentication:

1. It doesn't disable regular authentication, pam is only tried after  
checking regular sendsms-user's.
2. It allows for many pam configurations with different settings to  
coexist.
3. Logging reflects the pam configuration _and_ user (this required  
some additions to urltrans.c).

Having pam authentication allows kannel to authenticate using any pam- 
compatible module (passwd, ldap, radius, etc).

Another nice side effect is that new users could be added and  
passwords changed without needing to restart the service.

I'm working on the userguide patch as well.
