KEYS: Provide a function to load keys from a PGP keyring blob

Provide a function to load keys from a PGP keyring blob to the built-in
keyring:

	int preload_pgp_keys(const u8 *pgpdata, size_t pgpdatalen,
			     struct key *keyring);

Descriptions are generated from user ID notes and key fingerprints.  The
keys will actually be identified by the ID calculated from the PGP data
rather than by the description, so this shouldn't be a problem.

The keys are attached to the keyring supplied.

Looking as root in /proc/keys after the built-in keyring has been loaded:

383a00c1 I------     1 perm 1f030000     0     0 asymmetri \
				Red Hat, Inc. dbeca166: PGP.DSA dbeca166 []

Thanks to Tetsuo Handa <penguin-kernel@I-love.SAKURA.ne.jp> for some
pointing out some errors.
