* configure.in:
	Set DBUS_GLIB_THREADS_LIBS for apps using gthread-2.0

	* dbus/dbus-connection.c:
	* dbus/dbus-connection.h:
	Fix _dbus_connection_acquire_io_path and _dbus_connection_acquire_dispatch.
	Add dbus_connection_set_wakeup_main_function and use it when queueing
	incoming and outgoing messages.


	* dbus/dbus-dataslot.c:
	Threadsafe usage of DBusDataSlotAllocator

	* dbus/dbus-message.c: (dbus_message_get_args_iter):
	dbus_new can fail.

	* dbus/dbus-server-unix.c:
	Add todo comment

	* glib/dbus-gmain.c:
	Implement the new wakeup functions for glib.

	* glib/Makefile.am:
	* glib/test-thread-client.c:
	* glib/test-thread-server.c:
	* glib/test-thread.h:
	Initial cut at some thread test code. Not really done yet.
