unbundle: free temporary objects after use
This reduces peak RSS for larger unbundle operations by ~30 Bytes per
changeset on AMD64. This can't be a direct delete for Python 2.7, so
reset the object instead and leave a comment.
The efilesset object can't be deleted as it is referenced by the local
onchangelog function and Python 2.7 rejects a delete on the existance of
a nested scope.
