13 daysall: add export linknames for assembly symbols accessed from other packageCherry Mui
For Go symbols accessed from other package via linkname or assembly, we have an export linkname from the definition side. We currently don't always have the linkname directive for assembly functions, for which external accesses are allowed. We may want to tighten up the restriction. So add export linknames for the ones that are needed.

2021-12-09syscall: avoid writing to p when Pipe(p) failsRuss Cox
Generally speaking Go functions make no guarantees about what has happened to result parameters on error, and Pipe is no exception: callers should avoid looking at p if Pipe returns an error. However, we had a bug in which ForkExec was using the content of p after a failed Pipe, and others may too. As a robustness fix, make Pipe avoid writing to p on failure.

Use the libc fcntl (via syscall.fcntl) on aix and solaris like it is already done for darwin. For the syscall-based fcntl implementation use FcntlSyscall from internal/syscall/unix in order to get fcntl64 on 32-bit Linux systems. On aix, fcntl with F_DUPFD_CLOEXEC is not supported. Thus, defined F_DUPFD_CLOEXEC = 0 in the syscall package and check its value before calling fcntl(fd, syscall.F_DUPFD_CLOEXEC, 0). On js/wasm, fcntl is not supported thus let its implementation return ENOSYS directly.
