I've merged this to git master, with the default multiplex setting set
to "request" by default in QMI modems. This means that if you start a
connection normally as you would, e.g. with NetworkManager, the setup
will now always attempt to setup a multiplexed link for the data
connection. This is really no "API break" in ModemManager, as the
connection manager must have always used the data port reported in the
bearer object (which is why NetworkManager works without further
changes there).

Please report failures if any, this change requires a lot of testing.
