glibc: CVE-2015-1781: resolv/nss_dns/dns-host.c buffer overflow

Backport Arjun Shankar's patch for CVE-2015-1781:

A buffer overflow flaw was found in the way glibc's gethostbyname_r() and
other related functions computed the size of a buffer when passed a
misaligned buffer as input. An attacker able to make an application call
any of these functions with a misaligned buffer could use this flaw to
crash the application or, potentially, execute arbitrary code with the
permissions of the user running the application.
