Mark Wielaard e1e9a77564 Fix crash in linux [rt_]sigaction wrapper with bad old/new sigaction handler. ...

Since we try to modify the old/new sigaction handler before passing it
to the kernel we must make sure that (if they aren't NULL) it is safe
to use. If not we should bail out early with EFAULT.

Bug #369362
