* bus/connection.c: implement routines for handling connections, first thing is keeping a list of owned services on each connection and setting up watches etc. * bus/services.c: implement a mapping from service names to lists of connections * dbus/dbus-hash.c: add DBUS_HASH_POINTER * dbus/dbus-threads.c (dbus_static_mutex_lock): add functions to use static mutexes for global data * dbus/dbus-connection.c (dbus_connection_set_data): add new collection of functions to set/get application-specific data on the DBusConnection.
