The :c:type:`foo` only works properly with structs before
Sphinx 3.x.
On Sphinx 3.x, structs should now be declared using the
.. c:struct, and referenced via :c:struct tag.
As we now have the automarkup.py macro, that automatically
convert:
struct foo
into cross-references, let's get rid of that, solving
several warnings when building docs with Sphinx 3.x.

convert them into cross-references.
