* dbus/dbus-watch.c (_dbus_watch_new): handle failure to malloc
the watch
* dbus/dbus-server-debug-pipe.c (_dbus_transport_debug_pipe_new):
add some missing dbus_set_result
* bus/dispatch.c (bus_dispatch_add_connection): handle failure to
alloc the DBusMessageHandler
* dbus/dbus-transport.c (_dbus_transport_disconnect): don't ref
the transport here, since we call this from the finalizer; it
resulted in a double-finalize.
* dbus/dbus-transport.c (_dbus_transport_disconnect): fix a bug
where we tried to use transport->connection that was NULL,
happened when transport was disconnected early on due to OOM
* bus/*.c: adapt to handle OOM for watches/timeouts
* dbus/dbus-transport-unix.c: port to handle OOM during
watch handling
* dbus/dbus-auth.c (_dbus_auth_get_unused_bytes): return a
reference to unused bytes instead of a copy
* dbus/dbus-server.c (dbus_server_handle_watch): return FALSE for
out of memory
* dbus/dbus-connection.c (dbus_connection_handle_watch): return
FALSE on OOM
* dbus/dbus-timeout.c (dbus_timeout_handle): return FALSE for out
of memory
