Folks who have been suffering from io_uring coredumping issues please
give this a spin. I have lightly tested this version and more heavily
tested an earlier version which had more dependencies.
Unless I have missed something in cleaning up the code this should
be a comprehensive fix to the coredumping issues when using io_uring.
But folks please test and verify this. It has taken me long enough to
get back to this point I don't properly remember how the reproducer I
have was supposed to fail. All I can say with certainty is set of
changes has what looks like a positive effect.

signal: Move stopping for the coredump from do_exit into get_signal
coredump: Allow coredumps to pipes to work with io_uring
