/* Execute a command, optionally redirecting any of the three standard file
   descriptors to /dev/null.  Return its exit code.
   If it didn't terminate correctly, exit if exit_on_error is true, otherwise
   return 127.

   progname is the name of the program to be executed by the subprocess, used
   for error messages.
   prog_path is the file name of the program to be executed by the subprocess.
   If it contains no slashes, a search is conducted in $PATH.  An operating
   system dependent suffix is added, if necessary.
   prog_argv is the array of strings that the subprocess shall receive in
   argv[].  It is a NULL-terminated array.  prog_argv[0] should normally be
   identical to prog_path.

   dll_dirs is, on Windows platforms, a NULL-terminated list of directories
   that contain DLLs needed to execute the program, or NULL if none is needed.
   On other platforms, always pass NULL.

   If directory is not NULL, the command is executed in that directory.  If
   prog_path is a relative file name, it resolved before changing to that
   directory.  The current directory of the current process remains unchanged.

   If ignore_sigpipe is true, consider a subprocess termination due to SIGPIPE
   as equivalent to a success.  This is suitable for processes whose only
   purpose is to write to standard output.

   If slave_process is true, the child process will be terminated when its
   creator receives a catchable fatal signal.

   If termsigp is not NULL, *termsig will be set to the signal that terminated
   the subprocess (if supported by the platform: not on native Windows
   platforms), otherwise 0.

   It is recommended that no signal is blocked or ignored while execute()
   is called.  See spawn-pipe.h for the reason.  */
