* dbus/dbus-object-tree.c (handle_default_introspect_and_unlock):
	fix a double-unlock

	* dbus/dbus-connection.c
	(_dbus_connection_detach_pending_call_unlocked): add this

        Initial semi-correct pass through to fix thread locking; there are
	still some issues with the condition variable paths I'm pretty
	sure

	* dbus/dbus-server.c: add a mutex on DBusServer and appropriate
	lock/unlock calls

	* dbus/dbus-connection.c (_dbus_connection_do_iteration_unlocked):
	rename to add _unlocked
	(struct DBusConnection): move "dispatch_acquired" and
	"io_path_acquired" to use only one bit each.
	(CONNECTION_LOCK, CONNECTION_UNLOCK): add checks with !DBUS_DISABLE_CHECKS
	(dbus_connection_set_watch_functions): hacky fix to reentrancy
	(_dbus_connection_add_watch, _dbus_connection_remove_watch)
	(_dbus_connection_toggle_watch, _dbus_connection_add_timeout)
	(_dbus_connection_remove_timeout)
	(_dbus_connection_toggle_timeout): drop lock when calling out to
	user functions; done in a hacky/bad way.
	(_dbus_connection_send_and_unlock): add a missing unlock
	(_dbus_connection_block_for_reply): add a missing unlock

	* dbus/dbus-transport.c (_dbus_transport_get_is_authenticated):
	drop lock in a hacky probably unsafe way to call out to user
	function
