The reason for this choice is that in some language bindings we might
not have the SIG* symbols available, but there ought to still be a way
to send a default.  Hopefully people will read the docs :-)

I pushed it with s/signal/signum/.

Are we waiting on any other ABI breaks or would now be a good time to
do another 0.x release?
