2021-02-20all: go fmt std cmd (but revert vendor)Russ Cox
Make all our package sources use Go 1.17 gofmt format (adding //go:build lines). Part of //go:build change (#41184).

2019-10-21runtime: add netpollBreakIan Lance Taylor
The new netpollBreak function can be used to interrupt a blocking netpoll. This function is not currently used; it will be used by later CLs.

2019-10-20runtime: define nonblockingPipeIan Lance Taylor
This requires defining pipe, pipe2, and setNonblock for various platforms. The new function is currently only used on AIX. It will be used by later CLs in this series.

2017-10-20runtime: for kqueue treat EVFILT_READ with EV_EOF as permitting a writeIan Lance Taylor
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.

2016-09-26runtime: unify handling of alternate signal stackIan Lance Taylor
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.
