/* ------------------------------------------------------------------------------------------------------
Track memory ranges with macros for tools like Valgrind
address sanitizer, or other memory checkers.
The macros are set up such that the size passed to `mi_track_free_size`
matches the size of the allocation, or the newsize of a `mi_track_resize` (currently unused though).
The `size` is either byte precise (and what the user requested) if `MI_PADDING` is enabled,
or otherwise it is the full block size which may be larger than the original request.
