[conf] update settings_modules in confs
[jsbsim] fix IvyInit
[airborne] fix UpdateChecksum macro conflict
[state interface] update stateCalcPositionLla_i

Since LLA in float has bad precision, make this the last choice...
So we mostly first convert to ECEF and then use lla_of_ecef_i
which provides higher precision but is currently using the double function internally.

Also add mission conversions from ENU.
[tests] add first tests for state interface

and quiet some build output
