Previously the FSX/P3D driver tried to link a very specific SimConnect version
from the Windows Assembly cache. This caused issues with machines
which did not have this specific version of SimConnect in the assembly
cache since drivers refused to load without much information. Having a different
version of SimConnect in the assembly cache or even in the bin folder did
not help.
To fix this problem, SimConnect is now loaded and resolved manually at
runtime. This allows to try loading different versions from the assembly
cache or prefer to load the shipped one.
For this, the manifests are linked into the binary's resource section and
activated manually before loading. This has the positive effect, that
loading errors can be handled by code instead of raising a cryptic error and
aborting.
* base reange for request IDs
* all operations use offsets
* we can conclude what an id is used for (debugging)
plus
* minor Doxygen fixes
* some renamings
* Before this commit, only the true altitude was known for an aircraft situation. The pressure altitude was not available anywhere yet.
* This caused a wrong altitude in radar clients.
* We fix this reading the pressure altitude from the simulators and set it in the own aircraft situation.
* MS Flight Simulators have the pressure altitude in the APIs available.
* For X-Plane and emulated simulator, we need to calculate it from the pressure at sea level.
* Finally, we use the new available pressure altitude to send it to the FSD server.
