doc: add return types for function-like macros

Browse Source 
The Sphinx-3.0 c:function:: directive requires the return type.

Sphinx-3.0 also adds function-like macro support to the c:macro::
directive, which Sphinx-1.x and Sphinx-2.x do not support, but it
is probably a good idea to keep compatibility with slightly older
Sphinx for now.
