The combined decryption call feature was introduced in android R.
In earlier releases, subsamples were passed one at a time for
decryption within the plugin. A decryption request that consists
entirely of clear data should be passed on to OEMCrypto even if
no keys are loaded.
A sample might consist of subsamples of clear and protected data.
In legacy mode, this proved to be an issue for OEMCrypto if the clear
subsamples were passed on but the protected ones were rejected (b/110251447).
For legacy mode and in the absence of keys being loaded, the subsample will
be passed to OEMCrypto only if the clear lead/frame is in a single subsample
and not broken up across multiple subsamples.

This adds a unit test for to verify that a preloaded license may be
loaded into OEMCrypto. A preloaded license is a license that does not
have a nonce, and for which there is no license request. This is used
in CAS and ATSC.
I also updated the test version string to

The reference oemcrypto and testbed still use old style pointers, even
though we now require a more modern C++ compiler. Updated a few places
where smart pointer would be appropriate.

There are three situtations where error codes from a usage table
operations were not being mapped to unique CDM response types. These

This adds a log message to the oemcrypto unit tests so that if
somebody sends us a log, we can tell which version they are
running.
With this CL, the version string is
OEMCrypto unit tests for API 16.2. Tests last updated 2020-03-18
This can be found in the logs and in stdout when running the unit test
OEMCryptoClientTest.VersionNumber. One can verify the executable on
android using
strings $OUT/data/nativetest/oemcrypto_test | grep -i "oemcrypto unit tests"

from integration tests as it will always be true. We will still

After succeeding openSessionCommon(), when the call to
getSecurityLevel() fails, the code calls closeSession()
and only clears the sessionId if closeSession() fails.
We should always clear sessionId in this case.
Also, make it clearer that the status returned by
getSecurityLevel() does not overwrite the value from
openSessionCommon().

On unprovisioning, all persistent state/files are deleted. If a
provisioning session is opened soon after, |OEMCrypto_Terminate|
and |OEMCrypto_Initialize| will not be called. The (deleted) device
key will remain resident in memory and will not be regenerated until
|OEMCrypto_Initialize| is called. Any L3 licenses created will be
associated with a device key that does not exist, at least after
OEMCrypto is terminated.
By disabling delayed termination of OEMCrypto, OEMCrypto will be
terminated and initialized immediately on unprovisioning.
