    * alloc.c (test_setjmp, mark_stack):
    * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
    (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
    (png_load, my_error_exit, jpeg_load):
    * process.c (send_process_trap, send_process):
    Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
    The underscored versions are up to 30x faster on some hosts.
    Formerly, the code used setjmp+longjmp sometimes and
    _setjmp+_longjmp at other times, with no particular reason to
    prefer setjmp+longjmp.
