[pkix] PKCS #8 as an RFC

[Sean Turner <turners at ieca.com>]

Some may be unaware that PKCS #8 was published as RFC 5208 
(http://www.ietf.org/rfc/rfc5208.txt) and in it RSA transfered change 
control to the IETF.

The following draft updates PKCS#8 to add a CMS content type, a public 
key field, and address some of the comments Pasi raised during his IESG 
review 
(https://datatracker.ietf.org/idtracker/draft-kaliski-pkcs8/comment/80097/):
http://tools.ietf.org/html/draft-turner-asymmetrickeyformat-02

There's also an algorithm companion document that addresses some more of 
Pasi's comments:
http://tools.ietf.org/html/draft-turner-asymmetrickeyformat-algs-00

Comments are welcome on both.

Also note that http://tools.ietf.org/html/draft-ietf-sip-certs-09 
defines a MIME media type for PKCS#8.
