Alex Dale f696a48318 Logging CDM session ID on Decrypt() failures. 
[ Merge of http://go/wvgerrit/149690 ]

This changes extends the CryptoSession logging to include the OEMCrypto
session ID in its decrypt failure logs, and adds a new CdmSession
decrypt failure log which includes the CDM session ID.  The CDM session
directly maps to the MediaDRM session ID, making app debugging easier.

The Decrypt() code pathway is one of the most frequently called
portions of the CDM code, and the pathway attempts to make as few
logging calls as possible in order to keep latency low and log
verbosity to a minimum.  It is anticiapted that when a call to
Decrypt() fails, there will be a burst of failures as the app may
make several calls to Decrypt() before handling the first decrypt
error.

To keep logging low, the following rules are followed:
- CryptoSession: decrypt errors are only logged when the decrypt error
  changes.
- CdmSession: decrypt errors are only logged when the last call to
  decrypt had succeeded.

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:
