	* dbus/dbus-connection.c (dbus_connection_flush): don't spin on
	the connection if it's disconnected

	* bus/activation.c (bus_activation_service_created): use new
	transaction features to roll back removal of pending activation if
	we don't successfully create the service after all. Don't remove
	pending activation if the function fails.

	* dbus/dbus-list.c (_dbus_list_insert_before_link)
	(_dbus_list_insert_after_link): new code to facilitate
	services.c fixes

	* dbus/dbus-hash.c (_dbus_hash_table_insert_string_preallocated):
	new functionality, so we can preallocate the ability to insert
	into a hash table.

	* bus/connection.c (bus_transaction_add_cancel_hook): new function
	allowing us to put custom hooks in a transaction to be used for
	cancelling said transaction

	* doc/dbus-specification.sgml: add some discussion of secondary
	service owners, and disallow zero-length service names

	* bus/services.c (bus_registry_acquire_service): new function,
	splits out part of bus_driver_handle_acquire_service() and fixes
	a bug where we didn't remove the service doing the acquiring
	from the secondary queue if we failed to remove the current owner
	from the front of the queue.
