Support InputMode::kDevNull in Subprocess Subprocess always creates a pipe for stdin and passes it to the child process. This can sometimes be undesirable because (in a future commit) the child process might not have SELinux permissions to read from a pipe. This commit implements a new InputMode::kDevNull, which does not create a pipe for stdin. InputMode::kDevNull should always be used when args.input.empty(), but existing callers might be subtly relying on the pipe, so this commit doesn't change the default behavior. Tested: unit tests. **N.B.:** I haven't tested this on windows. Bug: 219393750 Change-Id: Ifd900f8be595439d12d6632c26426291c9064001
