When using the grace period, the CDM will need to override the values
given to use by the TEE (through OEMCrypto). Normally the first (and
last) decrypt times are stored securely by the TEE. To avoid extra
complexity in OEMCrypto, we will simply ignore the values given to us
by the TEE when using this feature.
However, the TEE will still enforce the (hard) license duration. So
only the rental/playback durations will be affected by malicious
editing of files.

Starting with OEMCrypto v12, we are guaranteeing to integration partners
that the buffers passed to OEMCrypto_DecryptCENC and
OEMCrypto_CopyBuffer will not be more than 100KiB (102400 bytes) in
size. For requests larger than this, we will first try to send the
buffer to OEMCrypto anyway. (in case the integration supports buffers
larger than the minimum) In the event that the buffer is rejected, we
will break it up into 100KiB chunks and send them down individually for
decryption.
Breaking a subsample into smaller subsamples necessitates knowledge of
how to update other decryption parameters (like the offsets and the IV)
that previously the CDM Core has not needed to know about. Until now,
this knowledge lived in the glue layer on the Android CDM and nowhere
on the CE CDM. Now, the CryptoSession has a subset of this knowledge, in
order to break up buffers successfully.
For testing purposes, the Mock OEMCrypto has been modified to only
support the smallest buffer size. In order to make sure the chunking
code was being exercised by them, the CE CDM tests had to have the
amount of data they decrypt increased by several orders of magnitude. To
contain this growth, I have moved the test data to its own file.
Bug: 31381719
Test: Ran the updated CE CDM integration tests
Test: Modified the OEMCrypto dynamic adapter to pretend both L3 and L1
only support 100KiB buffers on a Marlin and a Ryu. Confirmed that the
GTS H.264 tests (which have subsamples over 100KiB) passed still. A
similar test was attempted on Fugu but Fugu cannot pass these tests even
without this change present.

Automated tests reveal a race condition between closing
a session and the periodic policy timer event. If a close
session was in progress (WVDrmPlugin::closeSession) and
CdmEngine::CloseSession caused the CdmEngine::session_list_lock_
to be held, a call into CdmEngine::OnTimerEvent would pend on the
release of the lock.
The close session would continue to deallocate the session
and disable (stop) the policy timer leaving the CdmEngine::OnTimerEvent
call in an undefined state. This would result in an ANR.
This subtle race-condition was introduced when changes were made
to add in per-origin storage [ http://go/wvgerrit/17971 ]. This seems
to happen at a low frequency (~ < 0.5%).
To address a lock has been introduced to protect the map
WvContentDecryptionModule::cdms_.

This feature does not get used. Apps that call into the

on specific chip sets its being removed in NYC MR2.

When an offline release message is generated, a session is created
internally to generate the release and handle the release response.
If the response is never provided (network, server errors),
or there is an error when the response is being processed, the
session may not be closed. This change introduces a time to live for
release sessions of 60 seconds and will be reclaimed after this period.

This CL refactors some oemcrypto unit tests in preparation for adding
Provisioning 3.0 tests.
- The signature GenerateNonce has changed. Instead of the caller
passing in a pointer for the nonce, we store the nonce in a member
variable of Session.
- GenerateDerivedKeys is being replaced by InstallTestSessionKeys.
This sets up and calls the appropriate derive keys method. This
function is in the test class, instead of the session class so that
multiple sessions in a class can share the same wrapped rsa key.
This will be modified for provisioning 3.0 in a future CL.
- Rename tests that require a keybox. Some tests are specific for
using a keybox to request a DRM cert. These tests are renamed so we
can filter them out on devices that use an OEM Cert. Corresponding
tests for devices using provisioning 3.0 will be in a future CL.
- Some member variables and methods in the class Session were not
used. They are removed.
- Added openssl smart pointer.
- Comments. I added comments.
- clang format.
