There have been some failures with various RSA private keys. We add
them to the unit tests to make sure that OEMCrypto is able to load
these types of keys:
* Shorter: than normal private exponents. This seems to occur
occasionally even with Euler totients. But it occurs more with
Carmichael totients.
* 0-leading-byte: private exponents. This also occurs naturally for
both Euler and Carmichael totients.
* Carmichael: vs Euler totients. I think we may already have tests for
this. But just in case.

There was some confusion about who owned the OEMCrypto security level
string in a multithreaded environment. This is solved by caching the
security level at initialization time.

Test case WvCdmStreamingUsageReportTest.WvCdmStreamingUsageReportTest
was failing comparing "license duration" values returned when querying
for key information for licenses with unlimited "rental duration".
This is due to the new license duration model used for V16 licenses.
From the Widevine MediaDrm doc for "LicenseDurationRemaining":
For OEMCrypto v16+ (Android 11 and later), license duration is no
longer being enforced. If rental duration is set to never expire,
”9223372036854775807” (LLONG_MAX) will be returned.
Similarly, the test has been updated for "playback duration" queries
of the same case.

This is a manual merge of ag/14930112 to address an auto merge conflict.
Changes in the obfuscated L3 library:
L3 loads clock info from an encrypted file during initialization. There
is a bug which calls the clock loading function before the decryption
key gets intialized in InitializeEngine(). Clock will be loaded with bad
decrypted data, which caused playback failure after system reboot.
The fix is to move clock loading after InitializeEngine() to ensure
decryption key is ready.

The unit tests WvGenericCryptoTest expected an error code to be
returned from SelectKey. But we allow an invalid key to be signaled
either at SelectKey or later when the decrypt operation occurs.
This CL just updates the tests.

on a previous failure. Removing it from the list of expectations
as we cannot be certain that it will or will not be set unless we
know the previous state of the device.
