src/base/ftobjs.c, src/objs/fttype1.c, src/sfnt/ttcmap0.c,
    src/smooth/ftgrays.c: changed uses of "setjmp" and "longjmp"
    to "ft_setjmp" and "ft_lonjmp". Removed direct references to
    <stdio.h> and <setjmp.h> when appropriate, to eventually replace
    them with a FT_CONFIG_STANDARD_LIBRARY_H. Useful for the XFree86
    Font Server backend based on FT2.
