Move `cff_random' into `psaux' service. NOTE: Does not compile! Minor fix to allow both `cff' and `psaux' to use `cff_random'. * src/cff/cffload.c (cff_random): Move to... * src/psaux/psobjs.c: Here. * src/cff/cffload.h: Move corresponding declaration to `src/psaux/psobjs.h'. * include/freetype/internal/psaux.h (PSAux_ServiceRec): Register the function here... * src/psaux/psauxmod.c: And here. * src/cff/cffload.c, src/psaux/cf2intrp.c: Update code.
