Locks in earlier releases controlled access to sessions and the list
of sessions for each CdmEngine instance. This guarded against
concurrent access between session management (OpenSession,
CloseSession, etc), periodic timer calls and calls to Decrypt.
The list of sessions and locking was moved to a separate class
CdmSessionMap. This left open the possibility that a session
might be destructed, while being called to decrypt or invoked through the
timer. An attempt was made to add per-session locks in b/73781703
but this was found insufficient.
Per-session locks will be introduced in a future changelist, but for
now the coarser locks will be reintroduced.

The shared_ptr implementation was taken from a google3 implementation.
Updates to the reference counter needed to be atomic and were
platform dependent in the original code. These were not carried
over to this codebase. Race conditions between calls to decrypt and
the periodic timer, led to incorrect reference count values.
CdmSession objects were then destructed while references to
them still existed. Segfaults occurred when they were referenced.

Test: WV unit/integration tests, GTS GtsMediaTestCases tests and
24 hours of continuous Netflix playback.

The original fix was not sufficient to address all race conditions.
A subsequent CL will address them.

This CL
* corrects some of the test expectations
* switches test content used to test streaming with provider session tokens.
The policy of the earlier test content had changed.
* adds some more information to log messages

This fixes Widevine's getMetrics call so that it will return vendor
metrics through the Drm plugin 1.1 interface.

This CL adds some unit tests to verify that several OEMCrypto sessions
do not share nonce tables.

This avoids logging an unnecessary error, when the session is not found.
Bug: 79210873
Test: Wv unit/integration test, GtsMediaDrmTest, playback with Play
Movies and Netflix.

Models, which explains the difference between Provisioning 2.0 and
3.0.

Usage information is saved periodically, in order to avoid excessive
flash writes. This limits our session usage accuracy to
within a usage save period. Saving usage information when
closing a session is an improvement and addresses some failures
seen with Netflix compliance tests.

The device ID does not need to be sent in the client identification
information as it is either present in other fields or ignored
by the license service.
This also allows for build information to be reported during
provisioning for devices with OEM certificates.
