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.

# Disable the $CAP wire protocol capability.

if test -z "$CAP"
then
    echo "CAP environment variable not set."
