Add missing return statement
Update to work with latest Hare stdlib and Jinja

Changes include mostly:
 - *void -> *opaque
 - char -> types::c::char
 - jinja::contextfilter -> jinja::pass_context
 - avoid duplicate values (due to aliases) in switch statements

Disclaimer: I have no idea what I am doing :) but I did get the
vulkan-hello-world example to work and also the starfield GL example.
