module/keyring: add linux keyring module 



This module uses the keyutils library to fetch keys managed by the Linux
kernel keyring.  The keys are created implicitly in the probe_key()
callback.  For now, they need to be attached to the kernel's keyring
before requesting them.  The following patches will add the ability to
specify callout information which will allow  the kernel to instantiate
the keys if they're unavailable.
