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"

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.

In OEMCrypto v16, we dropped support for 'cens' and 'cbc1'. However, we
did not redefine the pattern (0,0) to be a valid pattern for 'cbcs', even
though it was no longer being used to signal 'cbc1'. Instead, we made
the CDM reject CTR with a pattern ('cens') and CBC with a (0,0) pattern
('cbc1') to mirror the behavior of OEMCrypto v16.
However, some apps have been using 'cbc1' mode to decrypt audio in
'cbcs' content. This is normally not possible but is possible for a
subset of content. Furthermore, it is easy to do by accident because of
the way most packagers package 'cbcs' audio and the special significance
Widevine has historically given the (0,0) pattern.
This patch updates the CDM to not reject CBC with a (0,0) pattern but
instead treat it as 'cbcs' content. To decrypt it correctly, the pattern
is treated specially inside the CDM core and converted to the
recommended equivalent pattern — (10,0) — before passing the content to
OEMCrypto.
For more specifics, please see the design doc: http://go/vclfg

With OEMCrypto V16 comes a new potential error code from calls to
DecryptCENC(). WARNING_MIXED_OUTPUT_PROTECTION may be returned by
supporting devices if one of the output devices does not meet the
required HDCP level for the decryption key/license; however the output
is instead restricted (by OEMCrypto) to devices that are secure. This
warning is informative to the CDM; but no action can/should be taken
by the CDM.
In addition, if DecryptCENC() returns an error/warning, it is likely
that the same status code will be returned on subsequent calls to
decrypt within the same crypto session. To reduce the number of logs
the CDM produces within the same crypto session only changes in error
codes are logged.
