Utilize the new IDetour::DetourSetup() code, IDetour::Attach and IDetour::Detach have been removed in favor of this (significantly reduces chance of user error). Since the template check happens in the idetour header, it is much more aggressive on type mismatches, such as a difference in parameter types, between the function and detour, will now raise a compile time error. As a result, some type mismatches have been fixed in this commit as well.
It was still crashing as the thisptr should actually be passed into the alloc callback. Changed and the function call is now identical to engine's impl. Tested in Debug, Profile and Release, Release has also been tested with LTCG.
Crash occurred as the arguments to the alloc/free callbacks would involve the 'this' pointer, and therefore, the registers would shift and misalign. The fix is to just make the functions static and call the pointers directly from the singleton exposed by the engine. Additional cleanup has been performed by adding typedefs for the function pointers.
Properly fix the aligned memalloc singleton in the SDK; the implementation now uses a callback based approach for calling the allocator and deallocator.
