[PATCH][RFC] Support saving the TODO list content in the session file (requires changes to core)

[naoliv]

It would be extremely welcome if we could save a session and also have the items in our TODO list included on it (so opening a session would restore the list, allowing us to fix/verify whatever was pending).

This really needs JOSM to add an interface for non-layer session exporters.

At this time, JOSM requires all session exporters to be dependent upon a layer.

I would welcome any way to save an unfinished todo list.

Eg working with the Tasking Manager, adding say 50 "Ready for validation" tasks to the todo list, then sanity checking them for missing buildings. Suppose when done 30 i have to stop, to proceed the following day. How nice would it be that i could somehow keep the remaining 20 unchecked tasks in the todo list for the next day.

In 18833/josm:

Fix #17052: Allow plugins to save state to session file

The primary feature request was for the TODO plugin to save the list elements for
a future session.

This allows plugins to register via ServiceLoader classes which need to be
called to save or restore their state.

In addition, this fixes an ordering issue with tests whereby the OsmApi cache
would be cleared, but the FakeOsmApi class would not recache itself when called.
