check if SIGINT handler is callable before triggering it...

check if SIGINT handler is callable before triggering it an apparent Python bug can cause `int not callable` when SIGINT handler is SIG_IGN It's a bit baffling that this behavior appears to be dependent on pyzmq version in IPython's own use, but the bug can be reproduced in a tiny amount of pure Python without zmq or IPython.
