wm4 14541ae258 Add checks for HAVE_GPL to various GPL-only source files
This should actually cover all of them, if you take into account that
some unchanged GPL source files include header files with such checks.
Also this was done already for the libaf derived code.

This is only for "safety" and to avoid misunderstandings.
