s/gnu-linux.h, s/hpux.h, s/iris3-5.h, s/iris3-6.h,

* s/gnu-linux.h:
(SIGPOLL, SIGURG): Do not undef.
(BROKEN_SIGPOLL, BROKEN_SIGURG): New macros.

* s/ptx4.h:
(SIGINFO): Do not undef.
(BROKEN_SIGINFO): New macros.

* s/aix3-1.h, s/bsd4-1.h, s/dgux.h, s/gnu-linux.h, s/hiuxmpp.h,
s/hpux.h, s/iris3-5.h, s/iris3-6.h, s/irix3-3.h, s/osf1.h, s/rtu.h,
s/sunos4-1.h, s/unipl5-0.h, s/unipl5-2.h, s/usg5-0.h, s/usg5-2-2.h,
s/usg5-2.h, s/usg5-3.h, s/xenix.h:
(open, close, read, write, INTERRUPTIBLE_OPEN,
INTERRUPTIBLE_CLOSE, INTERRUPTIBLE_IO): Remove.

* s/sol2-5.h (_LARGEFILE_SOURCE, _FILE_OFFSET_BITS): New macros.

	* s/usg5-3.h: Remove form feed.
	* s/template.h, m/template.h: Remove form feeds.

	* s/template.h: Mention that you should #define HAVE_TERMIO or
	HAVE_TERMIOS, but not both, and that HAVE_TERMIOS is preferred.
	* systty.h (EMACS_SET_TTY_PGRP): Don't assign the return value of
	tcsetpgrp to *pgid; it's just a status value.
	* config.h.in (HAVE_RANDOM): This shouldn't be defined on Linux
	systems using XFree386, and perhaps is inappropriate in general.
	* m/intel386.h: #undefine the integer size macros, since the Linux
	<values.h> file #defines them itself.
	* mem-limits.h (get_lim_data): Linux has the ulimit call; if it
	fails, fall back on ULIMIT_BREAK_VALUE.
	* process.c: Linux needs the WAITTYPE, etc. definitions.
	* unexec.c (hdr, ohdr): Linux has the ordinary `struct exec' type;
	no need to use SYSV names.
	* s/linux.h: New file.

	INTERRUPT_INPUT macros.

	':' elsewhere, just have it default to ':' if not #defined, and
	#define it to be ',' in s/vms.h; OS/2 will need it to be ';'.
	* s/vms.h (SEPCHAR): #define this to be ','.
	* s/template.h (SEPCHAR): Mention this.

	`configure' should be updated whenever support for a configuration
	is added or improved.
