gcc-plugins: Add structleak for more stack initialization
This plugin detects any structures that contain __user attributes and
makes sure it is being fully initialized so that a specific class of
information exposure is eliminated. (This plugin was originally designed
to block the exposure of siginfo in CVE-2013-2141.)
Ported from grsecurity/PaX. This version adds a verbose option to the
plugin and the Kconfig.
