This lets applications set the desired GPS update rate to reduce power usage

Set the AO_GPS_COURSE_VALID bit to signal that this part of the GPS
data is valid.

This was overwriting memory past the end of the ao_gps_tracking_data
array, which isn't a good idea.

Create a new global, ao_gps_new, which indicates new GPS position and
satellite data.
Use ao_gps_new as the new sleep/wakeup address.
Merge the separate gps position/satellite logging tasks into a single
function which waits for new data and writes out the changed values.

One case was using hex values instead of the #define equivalents.

The Max-7 parts just aren't happy switching baud rates, managing only
about half the time. Someday I'll figure out why, but until then, make
things work by just leaving the chips at 9600 baud

The new max 7 parts seem to be unhappy about switching baud rates, so
I've added a pile of debugging to help out. Some day, I'll figure out
how to make them work, this code is being left in place to help with that.

Provides a configuration option to set the ublox serial baud rate to
something other than 57600 baud

This caused the u-blox driver to use serial port 1 instead of the
project-specified serial port.

Take the gps_dump function from ao_gps_skytraq.c and move it to a new
file so it can be shared with the u-blox driver. That affects every
skytraq and u-blox user as they need to include the new file.

Airborne mode, < 4g (as good as it gets)
Only use 3D fixes (2D isn't very useful)
