This is based on a patch submitted by Amlogic.
When we're doing decrypt fallback, either in the CDM or the OEMCrypto
tests, we sometimes fall back to a point where we're synthesizing new
samples and/or subsamples for the content being decrypted. When this
happens and the output buffer is clear, we should limit the size of the
output buffer to only the space needed to hold the output.
Previously, we've been passing the entire output buffer to every call.
This can create a problem if the reason for the fallback is a lack of
enough memory to communicate the buffers to the TA, since the output
buffer will remain the same size as the total output. Restricting the
buffer passed to each call to only the space needed by that call will
reduce the memory requirement.

UDC specific: No DRM reprovisioning support
The SystemIdExtractor did not properly define behavior when working
with opened/closed CryptoSessions. Due to the CryptoSession's class
dual role of being both a session and a general handle into the
crypto engine, small bugs relying on undefined behavior which happened
to return expected output allowed tests to pass.
This CL makes the following changes:
1) Have SystemIdExtractor verify caller expectations when session is
open.
2) Improved SystemIdExtractor to operate when CryptoSession is opened
or closed.
3) Updates several SystemIdExtractorTest cases to better test defined
behavior without relying on undefined behavior.
4) Better code comments; hopefully some which will help prevent future
misuse of the internal APIs.

There are three changes here that should help reduce the
amount of duration test failures caused by clock skew.
First, we reported some skew when the test expected playback
to start immediately after loading the license. However,
with round-off, this could easily be more than 1 second. So
this does not warrent even a warning.
Second, the fake and real clocks were only synced after
computing how long to sleep. This is fixed by moving
SleepUntil to the TestSleep class and having it sync before
computing the delta and after doing the sleep.
Third, I am guessing that some failures due to unexpected
lenience were caused by the rental or playback clock being
started at the end of signing the license or the end of the
first decrypt instead of the beginning. We work around this
by recording how long these operations take, and then adding
this extra time at the end of the check for FailDecrypt.

OEMCrypto v17 introduced higher granularity in the device's HDCP V1
levels. Previously, all HDCP v1.x were group together. The change
was aimed towards server policy enforcement, not device enforcement.
Core code was updated, and could then be reflected in license
requests; however, reporting the new v1.x subversions was never
exposed to the higher app layers.
It is likely that devices which attempted to use specific 1.x versions
encountered test failures (for both CE CDM and Android CDM) as neither
implementations could handle such versions when communicating with
the app.
This change updates both CE CDM and Android CDM:
1) The CE CDM now uses the same subversion version comparisons as
performed by the core code.
2) The Android CDM will now recognize new HDCP levels, and not return
unexpected values.

For provisioning 4.0 devices, the DRM certificate serial number
was changing on a reprovisioning attempt or factory reset. The
app parameters sent up in the client identification name-value
pair field were being filtered out in provisioning requests.
This has been corrected for provisioning 4.0 stage 2
(DRM certificate request). There is no need to include them for
stage 1 (OEM certificate request).
The test case WvCdmRequestLicenseTest.ProvisioningSpoidTest
was created earlier to ensure that SPOIDs and DRM certificates are
stable. Unfortunately due to another bug b/250099615, the RKP service
was holding a connection to the Widevine TA for provisioning 4.0
devices. When native tests ran as their own process, L1 would fail
to load due to a connection failure and the test would run as L3.
The tests passed for provisioning 4.0 devices Pixel 7 and 8 when
they should have failed. This gave us a false sense of confidence
that the SPOIDs were stable.
For now a workaround is to run a shell command to kill the widevine
TA before running native tests.
$ adb shell pkill -f -9 widevine

For devices with a large number of usage entries, when restoring the
usage table a capacity check is performed. This checks that a new
entry can be created. This test was originally added as some devices
might enter a "stuck" state the table cannot be initialized.
To perform this test, a temporary crypto session is created and an
entry is created for that session. After successfully creating that
entry, the entry is deleted. However, because the session was left
open, the entry could not be deleted.
This change closes the capacity-check-session before deleting the
entry, as well as includes additional logs for helping future debugs.

LicenseKeys::GetAllowedUsage(). For entitled keys, it was calling
CanDecryptContent() instead of GetAllowedUsage() on the entitlement key
