C++ type conversions

These functions expose allowable type conversions as C++ helper functions.

Summary

This avoids having to explicitly reinterpret_cast in most cases.

Note: These functions only change the type of a pointer; they do not change the reference count of the referenced objects.

Note: There is no runtime checking that casts are correct. Call ArTrackable_getType beforehand to figure out the correct cast.
