The general code for setting a timespec value sometimes used set_nsec and sometimes used a combination of set_sec and set_nsec. Standardize on a setNsec function that takes a number of nanoseconds and splits them up to set the tv_sec and tv_nsec fields. Consistently mark setNsec as go:nosplit, since it has to be that way on some systems including Darwin and GNU/Linux. Consistently use timediv on 32-bit systems to help stay within split-stack limits on processors that don't have a 64-bit division instruction.

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.

Change all Unix systems to use stackt for the alternate signal stack (some were using sigaltstackt). Add OS-specific setSignalstackSP function to handle different types for ss_sp field, and unify all OS-specific signalstack functions into one. Unify handling of alternate signal stack in OS-specific minit and sigtrampgo functions via new functions minitSignalstack and setGsignalStack.

The conversion was done with an automated tool and then modified only as necessary to make it compile and run. In a few cases, defs_$GOOS_$GOARCH.go already existed, so the target here is defs1_$GOOS_$GOARCH.go. [This CL is part of the removal of C code from package runtime. See golang.org/s/dev.cc for an overview.] LGTM=r R=r CC=austin, dvyukov, golang-codereviews, iant, khr https://golang.org/cl/171490043
