Add error handling for outgoing WFC calls.
+ If POWER_OFF or OUT_OF_SERVICE is returned, show more specific
error messages based on WFC config and current wifi connectivity.
Assumes that IN_SERVICE will return if a call can be made,
regardless of the transport technology being used.
Assumes that OUT_OF_SERVICE will be returned if a call can not
be made and the radio is powered on.
Assumes that POWER_OFF will be returned if a call can not be
made and the radio is powered off.
