templater: use template context to render old-style list template

Prepares for dropping the 'templ' resource.

This means old-style list templates are processed by the same engine class
as the one for the list node. I think that's fine since templates for the
same list should be tightly coupled, and I believe the extension point for
the engine classes isn't actually used.

Now templatekw._showlist() is a compatibility wrapper for _showcompatlist(),
and will be deprecated soon. The function is still marked as private since
I plan to change the interface to get rid of closures capturing context and
mapping.
