Changes for correct pgrp behavior from Bob Glickstein

	<bobg@zindigo.z-code.com>:
	* m/iris4d.h (LIB_STANDARD): Do include -lbsd here.
	* s/irix4-0.h (USE_IRIX_BSDPGRP): #define this.
	(GETPGRP_NO_ARG): Don't #define this.
	* callproc.c [USE_IRIX_BSDPGRP] (Fcall_process): Call BSDsetpgrp
	instead of plain setpgrp.
	[USE_IRIX_BSDPGRP] (child_setup): Same.
	* emacs.c [GETPGRP_NO_ARG] (main, shut_down_emacs): CPP clauses
	deleted; this flag isn't needed anymore.
	[USE_IRIX_BSDPGRP] (main, shut_down_emacs): Call BSDsetpgrp and
	BSDgetpgrp instead of plain setpgrp and getpgrp.
	* process.c [USE_IRIX_BSDPGRP] (create_process): Don't call
	setpgrp before opening the tty.  Call BSDsetpgrp instead of
	setpgrp, after opening the tty.
	* sysdep.c [USE_IRIX_BSDPGRP] (sys_suspend,
	narrow_foreground_group, widen_foreground_group): Call BSDgetpgrp
	and BSDsetpgrp instead of getpgrp and setpgrp.
