largefiles: link the core dirstate._changing context to the lfdirstate one
This will be much cleaner and safer to make sure the two dirstates are in sync.
This way, the large-files dirstate will simply inherit the state of the main
dirstate, so if the core code does the right thing, the large-files code should
be right too.
