bookmark: make the search for divergent names more robust

We translate the "url we update from" and "the url in the config" into their
canonical representation. This is useful for urls that have multiple equivalent
forms:

  /foo/bar/ == file:/foo/bar/ == file:///foo/bar


eg: hg pull --config path.bar=/foo/bar/ file:/foo/bar

  $ hg init

  $ echo 123 > a
  $ hg add a
  $ hg commit -m "first" a

  $ mkdir sub
  $ echo 321 > sub/b
  $ hg add sub/b
  $ hg commit -m "second" sub/b

  $ cat sub/b
  321

  $ hg co 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

  $ cat sub/b 2>/dev/null || echo "sub/b not present"
  sub/b not present

  $ test -d sub || echo "sub not present"
  sub not present
