Implementing new pipe function to get around the limitation
that popen accepts a complete command. We need something which
accepts a program name, and a list of arguments, so that
we don't have to assemble together a correctly quoted string.
popen needs an alternative interface resembling execvp.
* eval.c (eval_init): New intrinsic registered, open-pipe-args.
* stream.c (struct stdio_handle): New member, pid.
(stdio_stream_print): Print the pid, if it is nonzero.
(pipevp_close): New close function.
(pipe_close): If h->pid is nonzero, it's a new-style pipe, which
must be closed with pipev_close.
(make_stdio_stream, make_pipe_stream): Initialize new stdio_handle
member to zero.
(make_pipevp_stream): New static function.
(open_pipevp): New function.
* stream.h (open_pipevp): Declared.
* txr.1: open-pipe-args added to stub section heading.
