Rahul Frias 78d2fa5e9e Improve android MediaDrm property latency 
[ Merge of http://go/wvgerrit/89848 ]

Apps query a number of properties at initialization. The mediaDrm
API getProperty allows the query of a single property at a time.
This causes a series of requests. If no crypto
sessions are concurrently open, a series of expensive OEMCrypto
Initialization and Termination calls will occur.

In this change OEMCrypto termination is delayed. If an OEMCrypto
Terminate is followed in close succession by an Initialize, neither
will occur avoiding the overhead. A timer enables a countdown process.
If no session activity occurs, the timer will eventually terminate
OEMCrypto and exit.

Bug: 136282358
Test: Android unit/integration tests

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:
