security: add a secctx_to_secid() hook
Add a secctx_to_secid() LSM hook to go along with the existing secid_to_secctx() LSM hook. This patch also includes the SELinux implementation for this hook. Signed-off-by: Paul Moore <paul.moore@hp.com> Acked-by: Stephen Smalley <sds@tycho.nsa.gov> Signed-off-by: James Morris <jmorris@namei.org>
