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.

This only changes the existing fields of the policy.
License::Policy::license_duration_seconds represents the end time
(relative to the license start time) that the license can be used.
This overriding other times if this is earlier.
License::Policy::rental_duration_seconds represents the end time
(relative to the license start time) that the license can be used
before playback starts. Once playback starts, this no longer applies.
License::Policy::playback_duration_seconds represents the end time
(relative to the playback start time) that the license can be used after
playback has started.

This adds support for offline playback. If the content contains
mutiple playlists which contain differing EXT-X-KEY attribute lists,
each of those keys will need to be saved and restored into separate
sessions.

Test: Added unit tests to cover new functionality. Some oem_crypto,
request_license_test failures but the same as without this CL.

This prevents a hang on contention for the lock if the datasource

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 CL modifies the haystack code to throw out the keybox if the
system id is wrong. This should help prevent b/33344450 from
persisting.
Part of this code change was to backport some updates to the haystack

The call table was meant to be a long-term way to track
the performance of all OEMCrypto function calls.
This feature does not get used. Apps that call into the
profiler can generate this from the history.
This change was designed to go into Android O
(go/wvgerrit/22503) but since the Call Table is causing problems
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.
Test: verified by unittests on angler
