WWAN fixes branch merged: autoconnect, rfkill cleanups, and low-power state

[Dan Williams <dcbw redhat com>]

Hi,

I've merged the dcbw/wwan-fixes branch, which adds some long-requested
behavior like WWAN autoconnect, better rfkill handling for multiple
modems, and sets modems to low-power state when they are disabled with
"nmcli radio wwan off".  I know people have been interested in these in
the past, so any further testing of these features would be appreciated.

Relevant upstream bug reports solved are:
