templates: define a {onelinesummary} keyword

It is sometimes useful to be able to use the configured
`command-template.oneline-summary` in higher-level templates. For
example, I would like to use it in an internal template that lists
commits in a "review unit" (kind of a pull request). This patch adds
support for that.

We may want to define a way of formatting a context using a
command-specific override (from
`command-templates.oneline-summary.<command>`), but that will have to
be a template function instead. I don't plan to do that, but I'm
mentioning it now in case reviewers would prefer that we use a no-arg
function (i.e. `{onelinesummary()}`) already today to prepare for
that.
