* include/freetype/internal/services/svpscmap.h, src/cff/cffcmap.c,
src/psaux/t1cmap.c, src/psnames/psmodule.c: Fix for the memory
leak described in bug #16759.
Fix memory leak described in Savannah bug #16759.
We change 'ps_unicodes_init' so that it also takes a 'free_glyph_name'
callback to release the glyph names returned by 'get_glyph_name'
