hgweb: allow symbolic revisions with forward slashes in urls

It's possible to have a branch/tag/bookmark with all kinds of special
characters, such as {}/\!?. While not very conveniently, symbolic revisions
with such characters work from command line if user correctly quotes the
characters. These characters also work in hgweb, when they are properly
encoded, with one exception: '/' (forward slash, urlencoded as '%2F'), which
was getting decoded before hgweb could parse it as a part of PATH_INFO.
Because of that, hgweb was seeing it as any other forward slash, that is, as
just another url parts separator.

For example, if user wanted to see the content of dir/file at bookmark
'feature/eggs', url could be: '/file/feature%2Feggs/dir/file'. But hgweb tried
to find a revision 'feature' and get contents of 'eggs/dir/file'.

To fix this, let's assume forward slashes are doubly-urlencoded (%252F), so
CGI/WSGI server decodes it into %2F. Then we can decode %2F in the revision
part of the url into an actual '/' character.

Making hgweb produce such urls will be done in the next 2 patches.

This test file aims at test topological iteration and the various configuration it can has.

  $ cat >> $HGRCPATH << EOF
  > [ui]
  > logtemplate={rev}\n
  > EOF

On this simple example, all topological branch are displayed in turn until we
can finally display 0. this implies skipping from 8 to 3 and coming back to 7
later.
