* add new priority parameter to avahi_glib_poll_new()

* beef up AvahiPoll a little to contain real timeout events
* cleanups in avahi-client
	* drop glib dependency
	* port to AvahiPoll system
	* put some "const"s and "static"s in to make gcc shut up
	* change all uses of malloc/free to avahi_malloc/avahi_new/avahi_free
