Subject: * 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
