As discussed, the old method of was going to have issues, and was not
going to help in the case of the structs containing pointers. I think we
are just going to have to be careful, as guarenteeing the internal
pointers are const is going to be very difficult.
As discussed, we don't really need the error checking specifically, as
we are just going to throw exceptions anyway, so this will make sure you
can check for 0 and be sure you catch any handle errors.
Handles will be replacing opaque pointers in the HAL for better compatibility and easier error checking. This commits adds the initial resource manangement and definition for handles.
