David Howells 3c58b2362b KEYS: Implement PKCS#8 RSA Private Key parser [ver #2]
Implement PKCS#8 RSA Private Key format [RFC 5208] parser for the
asymmetric key type.  For the moment, this will only support unencrypted
DER blobs.  PEM and decryption can be added later.

PKCS#8 keys can be loaded like this:

	openssl pkcs8 -in private_key.pem -topk8 -nocrypt -outform DER | \
	  keyctl padd asymmetric foo @s
