	* 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
