Get rid of the use of freetype internal headers in fcfreetype.c, since
    those headers will go away with freetype 2.2. Replace with public
    domain ftglue code from pango. Note that the patch removes some extra
    error checking in FT_Get_BDF_Property() and comments out the skipping
    of empty pcf fonts.
