	pread_chk, pread64_chk, recv_chk, recvfrom_chk, readlink_chk,
	getwd_chk, and getcwd_chk.  Plus appropriate CFLAGS definitions.

	* socket/Makefile (headers): Add bits/socket2.h.

	* string/bits/string3.h: Extend memset macro to check for zero 3rd
	parameter and use __memset_zero_constant_len_parameter in that case.
	* sysdeps/generic/memset_chk.c: Add
	__memset_zero_constant_len_parameter alias and linker warning.
	* debug/Versions: Add __memset_zero_constant_len_parameter to libc
	with version GLIBC_2.4.

	* sysdeps/generic/bits/types.h: Don't unnecessarily use __extension__
	in __STD_TYPE definition.

	* malloc/malloc.c (malloc_printerr): If MALLOC_CHECK_={5,7}, print
	the error message rather than program name.
