You should be able to use the PUTn type, like e.g. InvalidateFramebuffer. It
requires you to rename 'n' into 'count' in cmd_buffer_functions.txt, but then it
can autogen both client-side encoding and service side validation (as well as
tests).

Awesome. I'm a big fan of not writing boilerplate plumbing, and then getting it
wrong in the process.
