[PATCH 1/4] Installed-header compilation hygiene, 1/4 (easy changes).


These changes are straightforward, if tedious.  One of them deserves
special mention: it appears to me that grp-merge.h should not be
installed; it uses 'internal_function' and it only defines symbols
that are implementation-namespace and GLIBC_PRIVATE.  If I'm wrong,
some other changes to that header will be necessary.

zw

	BZ #20366, 1/4 (easy changes)

	* gmon/sys/gmon.h, inet/protocols/routed.h, inet/protocols/talkd.h
	* inet/protocols/timed.h, io/fts.h, resolv/arpa/nameser.h
	* resolv/resolv.h, sunrpc/rpc/rpc_des.h:
	Replace u_long with unsigned long, u_short with unsigned short,
	u_int with unsigned int, u_char with unsigned char, u_int8_t with
	uint8_t, u_int16_t with uint16_t, and u_int32_t with uint32_t.
	Include <stdint.h> if necessary.

	* grp/Makefile: Don't install grp-merge.h.
	* resolv/arpa/nameser_compat.h: Use __-prefixed byte order macros.
	* nis/rpcsvc/nislib.h: Include <rpcsvc/nis.h>.
	* sysvipc/sys/ipc.h: Remove unnecessary #warning.

	* sysdeps/unix/sysv/linux/netrose/rose.h: Include sys/socket.h
	and netax25/ax25.h.
	* sysdeps/unix/sysv/linux/sys/quota.h: Use __caddr_t instead of
	caddr_t in a function prototype.
	* sysdeps/unix/sysv/linux/sys/timerfd.h: Use __clockid_t instead of
	clockid_t in a function prototype.
