This corrects mapping for KeyStatus event kKeyStatusUsableInFuture in
the legacy WVDrmPlugin. It earlier reported DrmPlugin KeyStatusType
kKeyStatusType_StatusPending and now reports kKeyStatusType_UsableInFuture.
This fixes the test failure WVDrmPluginTest.MarshalsEvents

There were no function signature changes, so the API version number
did not change from 16.2. There were several grammar and spelling
errors. There were also the following corrections:
1. The description of OEMCrypto_LoadProvisioning now says that devices
with a keybox use keys derived from the keybox device key, and devices
using Provisioning 3.0 use keys derived from the session key. The
description was previously reversed.
2. The function OEMCrypto_SupportedPatterns is no longer
discussed. This function was never fully defined.
3. The function OEMCrypto_LoadRenewal no longer says that keys and key
control blocks should be verified. This is because the function
OEMCrypto_LoadRenewal processes a message with no key control
block. It should update timers for the entire license.
Test: doc and comment change only

The switch from LoadKeys to LoadLicense broke entitlement licenses
entirely because the LoadLicense path in CryptoSession didn't include
any affordances for updating the KeySession, unlike the LoadKeys path.
This patch adds code to handle this.

This CL modifies the system time used by the reference OEMCrypto so
that it recovers from a clock rollback. When the clock rolls back, it
now adjusts the current time and continues forward. This is needed
when running unit tests on some platforms that reset the clock at
the beginning of a test.

In `Combine Decrypt Calls to OEMCrypto`,
OEMCrypto_ERROR_BUFFER_TOO_LARGE is used as the default error code to
signal fallback to legacy decrypt (sending subsamples separately).
The error code would not be updated if no calls to OEMCrypto were
made (e.g. 0-length buffers).
This change resets error code to OEMCrypto_SUCCESS after fall back to
legacy decrypt. Consequently, buffers that do no require OEMCrypto
calls would return OEMCrypto_SUCCESS.

This CL updates the reference code, unit tests, and adapter to use the
new v16 function OEMCrypto_LoadDRMPrivateKey. This is just an API
change to allow ECC support in the future. The reference code does not
yet support ECC certificates, and the CDM code assumes that all
certificates have an RSA key.

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 syncs the document with the current version in Google Docs. Changes
since the last version:
* Specified that the Cobalt table only applies to First-Party Platforms
* Filled in gaps in Cobalt table
* Updated the Android R entry to reflect that some devices will stay on
v15
* Added further details on the contents of various OEMCrypto v16
versions
* Corrected Cobalt versions erroneously marked as Supported
* Updated copyright statement for 2020
* Reworded the header on the CE CDM section
* Corrected which CE CDM versions used OEMCrypto v8
* Put a section heading on the first table in the document to clarify
that it is not a table of contents nor a document version history

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
OEMCrypto unit tests for API 16.2. Tests last updated 2020-03-27
