    Make plugin build compatible with Firefox 3.1 renaming of npupp.h
    
    Checks which header to include, the older npupp.h or the newer npfunctions.h,
    falls back to the ancient copy included from the Netscape SDK if neither are
    found in either the default path or the pkg-config provided paths.
