Subject: Make map_pointer<T> typesafe

Instead of just using uint32_t, which would allow you to
assign e.g. a map_pointer<Version> to a map_pointer<Package>,
use our own smarter struct that has strict type checking.

We allow creating a map_pointer from a nullptr, and we allow
comparing map_pointer to nullptr, which also deals with comparisons
against 0 which are often used, as 0 will be implictly converted
to nullptr.
