DBusConnection: Pass a pending call around more often

Browse source 
If a pending call is provided, _dbus_connection_do_iteration_unlocked
checks whether it has completed or has a reply ready as soon as it
acquires the I/O path. If that's the case, then the iteration
terminates without trying to carry out I/O, so that the pending call
can be dispatched immediately, without blocking until a timeout is
reached. This change is believed to be necessary, but not sufficient,
to resolve #102839.

Based on part of a patch from Michael Searle on
<https://bugs.freedesktop.org/show_bug.cgi?id=102839>.
