Come to think of it... yeah, why would 3rd party stuff try to link to kdepim libraries?
I can't know for sure.  But really they shouldn't be doing that.

So updated plan:
 - put the source into kdepimlibs/gpl.
 - make sure the doxygen main pages say GPL on them
 - clearly state in the kdepimlibs/README and kdepimlibs/POLICIES file
    that there is GPL code in here
 - install a _gpl suffix to the installed libs, i.e. libfoo_gpl.so

Unless there are objections, I'd like to go ahead with this new plan.
Probably start moving stuff for next Monday.
