566fb0edfc Allow unaligned load/store in QVM interpreter/x86 compiler 
constructions like (dataMask & ~3) was used to protect against out-of-bound load/store when address is 4-byte closer to dataMask
 but at the same time it effectively cut low address bits for ALL load/store operations which is totally wrong in terms of conformance to ALLOWED (i.e. generated by q3lcc from C sources) low-level operations like packed binary data parsing

c5af65fe5f Fix passing arg9 (qvm only), arg10, and arg11 to vmMain for native libs and non-i386 compiled or interpated qvms. (Currently they aren't use in vmMain in game, cgame, or ui.) 
Fix passing args[11] to args[15] from vm to engine on ppc64 and sparc64. Some of the args are used by game bot prediction syscalls. May have been causing bugs. Note: This was fixed for x86_64 in r2163.

4cfbbe506c when interacting with QVMs, Clang/LLVM requires the standard use of the va_*() macros instead of (fast) call hacks

af5020c57c - Don't try to load QVM/DLL files on pure servers 
- Fallback after failed DLL load will be VMI_COMPILED, not INTERPRETED

9219cde4e8 - 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

4c242115dc - 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.

ffdc69f138 * Deleted code/unix/vm_x86.c - wtf was that about anyway? 
* Removed HAVE_VM_NATIVE
* Removed DLL_ONLY
* Replace HAVE_VM_COMPILED with NO_VM_COMPILED -- this means the JIT compiler
  should be enabled on the OS X and VC builds now
* Remove the remainder of the freetype building stuff

f62601ac53 don't call VM_Compile if it's not supported so the VM_Compile symbol 
isn't needed

d5fbff3f44 revert int->long change as it breaks on 64bit. Actually only 
VM_CallInterpreted hurts as VM_CallCompiled is only used on 32bit. Use
same arg types for consistency nevertheless.
