Nominally, OEMCrypto probably shouldn't modify the buffer descriptor we
pass into OEMCrypto_DecryptCENC(), but in practice, we know some
platforms do this, so we make defensive copies in
CryptoSession::DecryptInChunks() just in case. Turns out, some devices
also behave like this in OEMCrypto_CopyBuffer(), so we should also be
doing defensive copies in CryptoSession::CopyBufferInChunks().

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.

Usage information is saved periodically, in order to avoid excessive

within a usage save period. Saving usage information when
closing a session is an improvement and addresses some failures

The usage table keeps track of license duration by using the current
system time. However, if a user were to rollback the time, they can
effectively continue offline playback indefinitely. This changes the way
we compute time by computing offsets by which the user rollbacked the
time and adding it to the current time. This change also includes a test
to verify protection against rollback for usage entries that is only run
when the user is root.

This change creates a unique id in the cdm identifier in order to force

RemoveKeys now resets associated crypto and policy resources,
rather than just closing the crypto session. This results in a
MediaCodec.CryptoException with error code ERROR_NO_KEY
rather than ERROR_SESSION_NOT_OPENED, if decrypt is called
afterwards.
Error SESSION_NOT_FOUND_FOR_DECRYPT is made unique. Error codes
were also synchonized between various branches in the widevine repo.
