2576 - distinguish allocated addresses from others
This is the one major refinement on the C programming model I'm planning to introduce in mu. Instead of Rust's menagerie of pointer types and static checking, I want to introduce just one new type, and use it to perform ref-counting at runtime. So far all we're doing is updating new's interface. The actual ref-counting implementation is next. One implication: I might sometimes need duplicate implementations for a recipe with allocated vs vanilla addresses of the same type. So far it seems I can get away with just always passing in allocated addresses; the situations when you want to pass an unallocated address to a recipe should be few and far between.
