Extend a bit 'NO_MAIN'/'NO_USER_REFCOUNT'/etc. flags to ID allocation itself.

No real reason we keep this only to copying, creating ID outside of
database is handy as well!

Also, add helpers to add/remove an ID from Main, and to set/clear its
'user refcounting' status. Those will be useful in future complex ID
manipulation cases (like static override...).

Some cosmetic renaming.
