[PATCH 13/13] cobalt/assert: pipeline: add TODO() marker

From: Philippe Gerum <rpm at xenomai.org>

As its name suggests, TODO() can be added to the code in order to
highlight a place where some implementation bits are known to be
missing. Turning on CONFIG_XENO_TODO reveals the places where such
markers might linger by triggering a build time assertion, so that
they don't go unnoticed.

We may drop this helper when the port to Dovetail is complete.
