[ 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.
