we were getting some uninitialised variables. While it only showed up in
AP_SbusOut, it means we can't be sure it won't happen on other objects,
so safest to remove the approach
Thanks to assistance from Lucas, Peter and Francisco
previously the user would use the LOITER_UNLIMITED or LOITER_TIME mission commands to specify that the vehicle should remain active at the destination. This was cumbersome and not the best way to specify this behaviour because these two commands are valid for regular rovers that should not try to remain active at the destination.
AP_AHRS_NavEKF doesn't use the rangefinder, it just delegates the
calls to the right estimator.
For libraries/AP_AHRS/examples/AHRS_Test/AHRS_Test.cpp the initialization
order has also been modified to match the order on vehicles. It's more
correct since it passes a reference when EKF2/EKF3 are already
constructed, while thos constructors use a pointer. Ideally these
should be moved to an init() method though, or use a get_instance().
We should never include version.h or ap_version.h headers directly
on a header since this will trigger a complete rebuild of the
codebase when we commit to the repository. The ap_version.h header
is auto-generated containing information from the current commit.
If we include it in a header, every other file that ends up including
that header (directly or indirectly) will need to be rebuilt. No
ccache's cache beats having to do nothing when the header is just
not included.
version.h contains information that is kept on a struct inside
each vehicle. Rather than using the macros from each vehicle,
the getter should be preferred, which returns an AP_FWVersion
referente.
