clang: mark inline functions unused and add warning options
clang, unlike gcc, will warn on inline functions which are
unused. This can happen if a function is either intended to be used in
the future, or it is only used under certain config options. Mark
those functions with the "unused" attribute; not only does it quiet
the warning, but it also documents it for the user.
Shuffle around the warning options in configure and add a few more
that are specific to clang.
