	* dbus/dbus-connection.c (_dbus_connection_close_if_only_one_ref):
	Add a hack to make DBusNewConnectionFunction work right.

	* dbus/dbus-server-socket.c (handle_new_client_fd_and_unlock): use
	the hack here. Also, fix the todo about refcount leak.

	* dbus/dbus-server-debug-pipe.c (_dbus_transport_debug_pipe_new):
	and use the hack here

        * dbus/dbus-connection.c: Kill the "shared" flag vs. the
	"shareable" flag; this was completely broken, since it meant
	dbus_connection_open() returned a connection of unknown
	shared-ness. Now, we always hold a ref on anything opened
	as shareable.

	Move the call to notify dbus-bus.c into
	connection_forget_shared_unlocked, so libdbus consistently forgets
	all its knowledge of a connection at once. This exposed numerous
	places where things were totally broken if we dropped a ref inside
	get_dispatch_status_unlocked where
	connection_forget_shared_unlocked was previously, so move
	connection_forget_shared_unlocked into
	_dbus_connection_update_dispatch_status_and_unlock. Also move the
	exit_on_disconnect here.

	(shared_connections_shutdown): this assumed weak refs to the
	shared connections; since we have strong refs now, the assertion
	was failing and stuff was left in the hash. Fix it to close
	still-open shared connections.

	* bus/dispatch.c: fixup to use dbus_connection_open_private on the
	debug pipe connections

	* dbus/dbus-connection.c (dbus_connection_dispatch): only notify
	dbus-bus.c if the closed connection is in fact shared
	(_dbus_connection_close_possibly_shared): rename from
	_dbus_connection_close_internal
	(dbus_connection_close, dbus_connection_open,
	dbus_connection_open_private): Improve docs to explain the deal
	with when you should close or unref or both

	* dbus/dbus-bus.c
	(_dbus_bus_notify_shared_connection_disconnected_unlocked): rename
	from _dbus_bus_check_connection_and_unref_unlocked and modify to
	loop over all connections

	* test/test-utils.c (test_connection_shutdown): don't try to close
	shared connections.

	* test/name-test/test-threads-init.c (main): fix warnings in here

	* dbus/dbus-sysdeps.c (_dbus_abort): support DBUS_BLOCK_ON_ABORT
	env variable to cause blocking waiting for gdb; drop
	DBUS_PRINT_BACKTRACE and just call _dbus_print_backtrace()
	unconditionally.

	* configure.in: add -export-dynamic to libtool flags if assertions enabled
	so _dbus_print_backtrace works.

	* dbus/dbus-sysdeps-unix.c (_dbus_print_backtrace): use fprintf
	instead of _dbus_verbose to print the backtrace, and diagnose lack
	of -rdynamic/-export-dynamic
