We actually don't want a flexible array in this union, but rather a way
to access it byte by byte. This fixes the build for gcc >= 6

The new function can deal with a variable number of function parameters.
Additionally, I renamed the functions to norm(), because this is the
standard name used in several other projects.
this makes uBlox use the 3D velocity for ground course and speed,
ensuring we use a consistent value everywhere (so same vector in EKF
as in navigation)
Due to the way the headers are organized a single change in a
AP_GPS backend would trigger a rebuild for most of the files in the
project. Time could be saved by using ccache (since most of the things
didn't change) but we can do better, i.e. re-organize
the headers so we don't have to re-build everything.
This makes internal headers internal and then other libraries only
depend on the AP_GPS.h header.
ERB - Emlid Reach Binary protocol.
That driver designed for communication between Reach
and ArduPilot.
Provided opportunities:
- Detection of the driver
- Parsing of input messages: status of transmitter
and navigation information.
- Inject GPS messages from base
5hz update warnings are only valid if you have a fix, without a fix it adds load
to the GPS without any benefit. Our _5hz time messages are depenend upon GPS fix
time which isn't available yet
The ublox driver will now continuosly poll for the settings from the GPS and correct any that are found to be in correct.
This status is then reported to the arming library as an additional arming check, allowing the user to be sure that the
gps is correctly configured before using it. If a user has a GPS2 configured that is not present they will fail the arming
checks until after they have disabled the second GPS.
2 new parameters were introduced as well:
-GPS_AUTO_CONFIG: Will not request any configuration packets to attempt to change them. (If the packet is recieved then
a update will be sent to it, but in testing this scenario never occured. This is set to 1 or 0 to change the setting.
(Defaults to 1 enabling auto config)
-GPS_GNSS_MODE2: Behaves the same way as GPS_GNSS_MODE but only applies to the second GPS.
GPS drivers are now allowed 2 seconds of non responsiveness before being unloaded
when a NMEA sentence is corrupted we should discard it
completely. This change prevents us considering a set of sentences
that includes corrupted sentences from being seen as new data
