subrepo: handle svn tracked/unknown directory collisions

This happens more often than expected. Say you have an svn subrepository with
python code. Python would have generated unknown .pyc files. Now, you rebase
this setup on a revision where a directory containing python code does not
exist. Subversion is first asked to remove this directory when updating, but
will not because it contains untracked items. Then it will have to bring back
the directory after the merge but will fail because it now collides with an
untracked directory.

Using --force is not very elegant and only works with svn >= 1.5 but the only
alternative I can think of is to write our own purge command for subversion.

  $ "$TESTDIR/hghave" svn || exit 80

  $ fix_path()
  > {
  >     tr '\\' /
  > }

SVN wants all paths to start with a slash. Unfortunately, Windows ones
don't. Handle that.

  $ escapedwd=`pwd | fix_path`
  $ expr "$escapedwd" : '\/' > /dev/null || escapedwd="/$escapedwd"
  $ escapedwd=`python -c "import urllib, sys; sys.stdout.write(urllib.quote(sys.argv[1]))" "$escapedwd"`
