Roman 5036967343 barometer does not special height sensor offset because a barometer 
offset from the local origin is calculated if the primary source for
height is not baro

Roman c5d464b821 make range sensor height offset computation more robust 
- when switching to range finder use the current terrain estimate as
height sensor offset, otherwise spikes in the range measurements could lead
to a wrong offset

Roman 182ea43445 fixed baro offset calculation 
- do not subtract the height sensor offset variable when computing the
baro offset from the local origin. The baro height offset is calculated
when baro is not fused and so the height sensor offset used in that case
is associated to another sensor and has nothing to do with the baro.

Roman 3778f0921a ekf: enable range finder to be used for estimating height even if it's not 
the primary height source

- moved height control into single function in order to decide which sensor
should be used for estimating height
- under certain conditions allow to use the range finder to estimate height
even if it's not the primary height source
- fixed a bug where the delta time for the baro offset calculation was always
zero
- use methods to set height control flags to reduce code duplication and
to prevent bugs
