Subversion backend implementation

It is very important to distinguish the commit index and the commit id
which is assigned by Subversion. The first one is always handled as an
`int` by this implementation. The commit id assigned by Subversion on
the other side will always be a `str`.
There is a specific trap since the first commit will have the index
``0`` but the svn id will be ``"1"``.
