src: doc: Insert SYNOPSIS sections for man pages

In order to work with the post-processing logic in doxygen/Makefile.am,
SYNOPSIS sections must be inserted at the end of the module description
(text after \defgroup or \addtogroup)
(becomes Detailed Description in the man page).

Also a few minor updates including rename module uselessfns to do_not_use.
