Currently there are various circular dependencies between headers in core/. Let's get rid of these by making judicious use of forward declarations and moving includes into implementation files instead of having them in header files. Getting rid of circular header includes simplifies the code and makes various clang based tooling such as iwyu work much better on our code. The most important change is getting rid of the manager.h include in unit.h which is possible thanks to the previous commits. We also move the OOMPolicy and StatusType enums to unit.h to remove the need for other unit headers to include manager.h to get access to these enums.
