Rahul Frias e538c96131 Save and retrieve key information from licenses and usage records 
[ Merge of http://go/wvgerrit/120512 ]

Wrapped DRM private keys are loaded when a key request is made or when
offline/usage sessions are restored. They were earlier loaded when a
session was opened.

For streaming sessions, key material will be fetched from the default
or legacy certificates and loaded when a key request is made.

For offline and usage sessions, key material may be retrieved from
license or usage records if available. If not available, information
associated with the legacy certificate will be loaded.

Certificate and wrapped keys are also written out when an offline
license or usage record is saved.

README 

This is the source code for the Widevine Content Decryption Module (CDM) for the
Android OS.  It provides the libwvdrmengine plugin for DRM.

Partners who are integrating a device should be familiar with the documents in
the docs directory.

This source code is NOT open source, and is not part of AOSP.  However, it is
released to partners external to Google after official Android releases.  For
this reason, partners should look for bug fixes and software updates on the
widevine branches:
