cmdutil: expand filename format string by templater (BC)

This is BC because '{}' could be a valid filename before, but I believe good
programmers wouldn't use such catastrophic output filenames. On the other
hand, '\' has to be escaped since it is a directory separator on Windows.
Thanks to Matt Harbison for spotting this weird issue.

This patch also adds cmdutil.rendertemplate(ctx, tmpl, props) as a simpler
way of expanding template against single changeset.

.. bc::

   '{' in output filename passed to archive/cat/export is taken as a start
   of a template expression.

Template fragments in file name:

  $ hg export -v -o '{node|shortest}.patch' tip
  exporting patch:
  197e.patch

Backslash should be preserved because it is a directory separator on Windows:

  $ mkdir out
  $ hg export -v -o 'out\{node|shortest}.patch' tip
  exporting patch:
  out\197e.patch

Still backslash is taken as an escape character in inner template strings:

  $ hg export -v -o '{"out\{foo}.patch"}' tip
  exporting patch:
  out{foo}.patch

  $ hg export -o '%x.patch' tip
