Michael du Breuil 561acb372e AP_GPS: SBF send port enable string on start 
Also prohibts SBF, GSOF, NOVA drivers from getting config strings not
meant for them

Dr.-Ing. Amilcar Do Carmo Lucas d3a18e803e AP_GPS: Fix MAVLink message field SYSTEM_TIME.time_unix_usec when GPS_AUTO_SWITCH = blend 
The mavlink message field SYSTEM_TIME.time_unix_usec works fine with GPS_AUTO_SWITCH == 0 (no switch) or ==1 (usebest)
But when GPS_AUTO_SWITCH == 2 (blend) then state[GPS_BLENDED_INSTANCE].last_gps_time_ms gets initialized with 0 and never rewritten.

The consequence: SYSTEM_TIME.time_unix_usec gets stuck at zero.
The solution: Do not reset state[GPS_BLENDED_INSTANCE].last_gps_time_ms because it would overwrite the correct value already set on line 1149

Andrew Tridgell 82e7e44cc3 AP_GPS: fixed UAVCAN as 2nd GPS 
This fixes the issue here:

  https://discuss.ardupilot.org/t/ac3-6-dev-dual-gps-issues/19172

thanks to Francisco for spotting the issue

this is tested with UAVCAN as 2nd GPS, ublox as primary

Michael du Breuil c7a89d5aa0 AP_GPS: Set unknown DOP's to UINT16_MAX, rather then 9999 
This fixes the MAVLink reporting for unknown dops, and avoids the situation where a GPS driver could report a worse DOP then we could handle.

Also corrects an apparent error in the HIL_GPS MAVLink message, where we would always select the unknown dop value rather then provided DOP.

Dr.-Ing. Amilcar Do Carmo Lucas 2d5033b132 AP_GPS: Use SI units conventions in parameter units 
Follow the rules from:
http://physics.nist.gov/cuu/Units/units.html
http://physics.nist.gov/cuu/Units/outside.html
and
http://physics.nist.gov/cuu/Units/checklist.html
one further constrain is that only printable (7bit) ASCII characters are allowed
