This doesn't compile :-(

The thing is that `asan_interface_internal.h` defines pretty much the same set of functions that I do here using the `INTERFACE_FUNCTION` macro. For editing simplicity reasons, the `INTERFACE_FUNCTION` macro doesn't know the argument types of the function, so we end up with conflicts between two declarations:
asan_dll_thunk.cc(238) : error C2733: '__asan_memcpy' : second C linkage of overloaded function not allowed
asan_interface_internal.h(156) : see declaration of '__asan_memcpy'
asan_dll_thunk.cc(238) : error C2440: 'type cast' : cannot convert from 'overloaded-function' to '__sanitizer::uptr'
Context does not allow for disambiguation of overloaded function
This is basically the reason why I haven't just used `__asan_init` in the first place...
Can we move declarations/definitions between headers somehow or have a minimalistic declaration-only new header for `__asan_init`?

Suggestion: can probably use the `#` macro operator here?
