This now works to a certain extent. When an update attempts to apply
changes to a moved tree it causes a tree-conflict on the move source
just like 1.7. When resolving the tree-conflict the user can choose to
apply the changes to the move destination and this now updates the NODES
rows for the move destination and merges the changes in the working
files. This may in turn generate tree-conflicts in the move destination
for nested moves, deletes, obstructions. For nested moves the
tree-conflict can also be resolved by applying the changes to the move
destination.

Things that need more work:

  - tests.

  - handling deleting files/dirs from the working files, at present they
    are left unversioned.

  - handle an update that makes no text/property/tree changes in the
    move source, probably by creating a tree-conflict during the
    post-drive revision bump.

  - switch can cause the tree-conflicts on the move source, at present
    the new code hard-codes 'update'.

  - more tests (again).
