[BZ #4381]

	* nss/nss_files/files-hosts.c (HOST_DB_LOOKUP): Ensure sufficient
	alignment of buffer and tmp_buffer.
	* nis/nss_nis/nis-hosts.c (internal_nis_gethostent_r,
	internal_gethostbyname2_r, _nss_nis_gethostbyaddr_r): Ensure sufficient
	alignment of buffer.
	* resolv/nss_dns/dns-hosts.c (getanswer_r): Likewise.  Handle buflen
	bigger than INT_MAX.
	* resolv/nss_dns/dns-network.c (getanswer_r): Likewise.  Add errnop and
	h_errnop arguments.  Fail if buflen is too small.
	(_nss_dns_getnetbyname_r, _nss_dns_getnetbyaddr_r): Adjust callers.
