The type system should have never been relegated to libgobject: it's a low level API to register types at run time. Having GType inside libglib allows us to use the type system information everywhere: - generic but type safe storage data types - explicit memory management semantics for all data types - enumeration types for all flags Having the type system inside libglib also allows us to create new and better fundamental types in the future, like sum types, option types, tuples, and generic types. Moved: - gatomicarray - gboxed - genums - gtype - gtypeplugin - gvalue The move is mostly Git surgery, but given the amount of internal API surface, it results in a single commit to avoid breaking bisectability. We need to maintain `gobject/gvaluecollector.h` as a publicly installed header but, to avoid issues in case of excessive inclusions, we make it conflict with `glib/gvaluecollector.h`.
