This gets rid of the confusing and brittle g2Tmp static variable, replacing it with individual local variables instead.
This expresses its dual nature a bit more clearly than a void pointer.
It seems dangerous to pretend that the pointers to pointers inside sharedEntityMapper_t are all ordinary pointers. Instead, let's use a union type to clearly distinguish between ordinary native pointers and 32-bit pointers into QVM memory that need to be translated first. I chose to only use a single union-pointer-type, instead of one per pointed-to type, for simplicity. I added some light type annotations using no-op defines, but there's no actual type checking. I did all this in the pursuit of properly marking Vehicle_t as having different memory layouts in native and QVM. It is only used for null-checks at the moment, which is safe, but if somebody were to try to access its fields, they need to be aware of the type mismatch.
We need to use the gentityMapper instead, to properly handle QVM.
