[PATCH] Name Service Switch (NSS) directory backend

[agx@…]

This implements a simple NSS based user and group lookup directory service (it basically uses what's returned by the python's pwd and grp modules).

You can set a prefix for groups and ranges for uids/gids to make sure system users/groups don't end up having calendars.

This directory service is not doing any authentication, simply use Kerberos.

twistedcaldav.directory.nss.NssDirectoryService has some documentation in the top of the file.
