Merged that branch to git master.

For the 3GPP vs 3GPP2 issue during runtime, we may end up needing a
SetCurrentCapabilities() method or so :/ And maybe force a reboot of the
module if current capabilities change, so that both the internal state
of the modem (e.g. exposed ifaces) and also the external state (e.g. NM)
get updated accordingly. We already do something very similar with the
Firmware interface and the E396, which allows firmware switching through
QMI.
