On FreeBSD, the game used to crash when loading the last level of RoE
(d3xp), while loading models/david/hell_h7.ma.
The problem could be reproduced on Linux whith #define USE_LIBC_MALLOC 1
and clang's AddressSanitizer.
Turns out that this file specifies a vertex transform for a non-existent
vertex (index 31, while we only have 0-30) and thus the bounds of
pMesh->vertexes[] are violated.
I added a check to ensure the index is within the bounds and a Warning
if it isn't.
It should work now. If however it turns out that more files have this
problem, maybe .ma is parsed incorrectly and we need a differently fix.
(Should) fix#138
Don't include the lazy precompiled.h everywhere, only what's
required for the compilation unit.
platform.h needs to be included instead to provide all essential
defines and types.
All includes use the relative path to the neo or the game
specific root.
Move all idlib related includes from idlib/Lib.h to precompiled.h.
precompiled.h still exists for the MFC stuff in tools/.
Add some missing header guards.
