hgweb: expose list of per-repo labels to templates

hgweb currently offers limited functionality for "classifying"
repositories. This patch aims to change that.

The web.labels config option list is introduced. Its values
are exposed to the "index" and "summary" templates. Custom
templates can use template features like ifcontains() to e.g.
look for the presence of a specific label and engage specific
behavior. For example, a site operator may wish to assign a
"defunct" label to a repository so the repository is prominently
marked as dead in repository indexes.

  $ cat > abortcommit.py <<EOF
  > from mercurial import error
  > def hook(**args):
  >     raise error.Abort("no commits allowed")
  > def reposetup(ui, repo):
  >     repo.ui.setconfig("hooks", "pretxncommit.nocommits", hook)
  > EOF
  $ abspath=`pwd`/abortcommit.py

  $ cat <<EOF >> $HGRCPATH
  > [extensions]
  > mq =
  > abortcommit = $abspath
  > EOF

  $ hg init foo
  $ cd foo
  $ echo foo > foo
  $ hg add foo

mq may keep a reference to the repository so __del__ will not be
called and .hg/journal.dirstate will not be deleted:

  $ hg ci -m foo
  error: pretxncommit.nocommits hook failed: no commits allowed
  transaction abort!
  rollback completed
  abort: no commits allowed
  [255]
  $ hg ci -m foo
  error: pretxncommit.nocommits hook failed: no commits allowed
  transaction abort!
  rollback completed
  abort: no commits allowed
  [255]

  $ cd ..
