Change NMEA mode setting, thus major changes in gpsd_error_model().

The start of this overly large patch was to simply move the test
for MODE_2D/3D flipping, which only affect NMEA 183, back into
driver_nmea0813.c

But that was intertwined with how gpsd_error_model() computes
derived variables, which required major changes to how NMEA 183
mode_2D/3D are set.

This ultimatly led to major regression test results.  Almost all for
the better.

I tried to break it up, but moving from one paradigm to another
needed one big jump...
