* dbus/dbus-threads.c (dbus_mutex_new, dbus_condvar_new): with
	DBUS_BUILD_TESTS, actually alloc/free a block of memory for
	the mutex, so we can check for proper memory management
	and OOM handling.

	* dbus/dbus-dataslot.c: remove the mutex from
	DBusDataSlotAllocator and lock it manually when using it,
	to simplify fitting it into the global slots framework.

	* dbus/dbus-threads.c (init_static_locks): rework how we're
	handling global locks so they are easily shut down.

	* bus/policy.c (bus_policy_append_rule): fix

	* bus/test-main.c (main): check for memleaks

	* dbus/dbus-test.c (dbus_internal_do_not_use_run_tests): make
	test suite check for memleaks

	* dbus/dbus-memory.c: add support in test mode for tracking
	number of outstanding blocks
