workaround for GHOST glibc vulnerability CVE-2015-0235

[Constantine Shulyupin <const () makelinux com>]

CVE-2015-0235-workaround is a shared library wrapper with additional checks
for the vulnerable functions gethostbyname2_r and gethostbyname_r .

The proper solution for CVE-2015-0235 is to upgrade glibc to at least
glibc-2.18.

In some cases, an immediate glibc upgrade is not possible, for example in
custom production embedded systems, because such an upgrade requires a
validation of the whole system.

In such cases, this workaround provides a hot fix solution, which is easier
to validate.
