[BUG?] svn_fs__dag_remove_node does not cleanup all references to the deleted node

When a node-rev is deleted from the fs (because it was added then deleted in
the same revision), svn_fs__dag_remove_node can leave behind references to
it in the copies and changes tables.

I haven't observed this causing any actual problems, except that if in the
future there is a tool which verifies the consistency of svn repositories,
it will find 'corruption'.

I think what needs to happen is:

* Scan the txn containing the node-rev for copies. Check each copy, if it
refers to the node-rev being removed, delete it from the copies table and
txn record.
* Scan the changes table and delete any change-records referring to the
node-rev being removed.

Comments?

Max.
