runtime: for kqueue treat EVFILT_READ with EV_EOF as permitting a write On systems that use kqueue, we always register descriptors for both EVFILT_READ and EVFILT_WRITE. On at least FreeBSD and OpenBSD, when the write end of a pipe is registered for EVFILT_READ and EVFILT_WRITE events, and the read end of the pipe is closed, kqueue reports an EVFILT_READ event with EV_EOF set, but does not report an EVFILT_WRITE event. Since the write to the pipe is waiting for an EVFILT_WRITE event, closing the read end of a pipe can cause the write end to hang rather than attempt another write which will fail with EPIPE. Fix this by treating EVFILT_READ with EV_EOF set as making both reads and writes ready to proceed. The real test for this is in CL 71770, which tests using various timeouts with pipes.

runtime: write sigsetstack for Darwin, fix sigaction arg It turns out that the second argument for sigaction on Darwin has a different type than the first argument. The second argument is the user visible sigaction struct, and does not have the sa_tramp field. I base this on http://www.opensource.apple.com/source/Libc/Libc-1081.1.3/sys/sigaction.c not to mention actual testing. While I was at it I removed a useless memclr in setsig, a relic of the C code. This CL is Darwin-specific changes. The tests for this CL are in https://golang.org/cl/17903 .

runtime: use uintXX instead of *byte for si_addr on Darwin Currently, Darwin's siginfo type uses *byte for the si_addr field. This results in unwanted write barriers in set_sigaddr. It's also pointless since it never points to anything real and the get/set methods return/take uintXX and cast it from/to the pointer. All other arches use a uint type for this field. Change Darwin to match. This simplifies the get/set methods and eliminates the unwanted write barriers.
