priseborough 04036d7777 AP_NavEKF : Updated GPS glitch protection logic
This adds new functionality to the detection and compensation of GPS
glitches:

1) A maximum allowable innovation is calculated using the GPS noise
parameter multiplied by the gate, with an additional component allowing
for growth in position uncertainty due to acceleration error since
the last valid measurement
2) Includes per vehicle type values for the acceleration error limit
3) If the innovation length exceeds the maximum allowable, no fusion occurs
4) If no fusion has occurred for long enough such that the position uncertainty
exceeds the maximum set by a per vehicle parameter or a maximum time, an offset
is applied to the GPS data to so that it matches the value predicted by the filter
5) The offset is never allowed to be bigger than 100m
6) The offset is decayed to zero at a rate of 1.0 m/s to allow GPS jumps to
be accommodated gradually
7) The default velocity innovation gate has been tightened up for copter and rover
8) The variance data logging output has been updated to make it more useful

Andrew Tridgell 368daf89f1 AP_GPS: new GPS API
This is a complete rewrite of the GPS driver structure, with a static
main driver and separate backend drivers. This will allow proper
support for multiple GPSes, and will allow parameters to be set on the
GPS object

Andrew Tridgell 2dd92832dc AP_GPS: support multiple AP_GPS_Auto drivers
move all static variables into a dynamically allocated structure in
the AUTO driver which gets freed when we have found a GPS type

Andrew Tridgell 3c4389180e AP_GPS: removed GPS_406 driver
this driver was untested and badly structured. If we want to support
the 406 we can revive it and do it properly
