- Small change to search path order - local files not in .pk3s take precedence over files in pk3s. Should make life easier for modders/mappers wanting to override textures that are already contained in some older pk3
...
- Make VM loading more robust, change loading order: when vm_* == 0 first try loading DLL, then QVM in *each* search directory/path
- Fix FS_FileForHandle that would return a FILE pointer to invalid file handle 0

Use scaled indexing mode n=4 for addressing opStack, this way we can use the 8 bit offset value in %%bl to address an OPSTACK_SIZE of 1024 which was the old value.

Define stack sizes at central place

also reverts bug 4282 as stack is included in bss already so nothing that needs fixing

Throw an error if vm->callLevel is set and VM_Free is called.

- change long to intptr_t for 64bit windows compatability
...
- change vmMain arguments back to int. 64bit types are apparently not
needed there. Only the syscall function needs them.

appropriate for open source Q3

VC and OS X builds (easy to fix though)

VM_CallInterpreted hurts as VM_CallCompiled is only used on 32bit. Use
same arg types for consistency nevertheless.
