* add new function pa_check_in_group()

* abstract credential APis a little bit by introducing HAVE_CREDS and a structure pa_creds
* rework credential authentication
* fix module-volume-restore and friends for usage in system-wide instance
* remove loopback= argument from moulde-*-protocol-tcp since it is a superset of listen= and usually a bad idea anyway since the user shouldn't load the TCP module at all if he doesn't want remote access
* rename a few variables in the jack modules to make sure they don't conflict with symbols defined in the system headers
* add server address for system-wide daemons to the default server list for the the client libs
* update todo
