Browse Source 
[ Merge of http://go/wvgerrit/116944 ]

This change is the last part of a three part change for restructing
the root of trust used by the reference implementation.

OEM Certificates are now managed by the root of trust of the crypto
engine.  Previously, OEM certs where handled separately on a session
by session basis.
