D680: scmutil: handle conflicting files and dirs in origbackuppath

[quark (Jun Wu)]

  If it's just file and directory conflict, maybe we can encode the path so it becomes impossible to have such conflict. See `_encodedir` in `store.py` for an example. It requires a suffix so partially reverts https://phab.mercurial-scm.org/D679 though.
