* watchquagga.c: (handle_read) Use new ERRNO_IO_RETRY macro.

	* watchquagga.c: (try_connect) Use new set_nonblocking function instead
	  of calling fcntl directly.

	* watchquagga.c: (run_job) Fix bug: delay.tv_sec was being used
	  without having been initialized when the "force" argument was true.
	  (try_restart) When phased restart is stopping the routing daemons,
	  it should tell run_job to update the restart interval.
	  (phase_check) In final step of phased restart when the routing
	  daemons are being started again, tell run_job not to update
	  the restart interval (this is now done when the daemons are
	  stopped).

	* watchquagga.c: In several places, cast pid_t to int for printf to
	  avoid complaints on Solaris 8.

	* watchquagga.c: Fix headers: get most stuff from zebra.h.

	* watchquagga.c: Add missing getopt.h include

	* watchquagga.c: Try for gcc 2.95 compatibility (avoid %z and a tricky
	  initialization).

	* watchquagga.c: Add -b option to circumvent difficulties passing
	  embedded spaces in command-line arguments.  This is an ugly hack,
	  we should probably use a config file instead.

	* watchquagga.c: Use new config.h define for DAEMON_VTY_DIR.
