formatter: support json formatting of long type

By luck, we appear to not pass any long instances into
the JSON formatter. I suspect this will change with all the
Python 3 porting work. Plus I have another series that will
convert some ints to longs that triggers this.

def sigshow(*args):
    sys.stderr.write("\n")
    traceback.print_stack(args[1], limit=10, file=sys.stderr)
    sys.stderr.write("----\n")

    signal.signal(signal.SIGQUIT, sigshow)
    try:
        signal.signal(signal.SIGINFO, sigshow)
