The final spec for CENC says that partial encrypted blocks are only
allowed for "cenc" mode, and not for "cens" mode. Also, the
pattern_offset must be 0 for all calls to OEMCrypto_DecryptCENC.

Notice that this CL affects documentation and test code only. No
production code is affected.

This CL changes the android/build_and_run_all_unit_tests.sh script to
push exectuables to /data if it can't push to /system/bin.
The script run_all_unit_tests.sh will check if test files are in /data
and run those first, if not, it runs the files in /system/bin.
This change is needed to test unit tests on devices where /system/bin
is a read only file system, even after running "adb remount".
This CL will help verify, but will not fix

Because Widevine core always has a decrypt mode set, even on unencrypted
calls where we potentially do not know the crypto mode, it will reject
unencrypted decrypt calls for sessions that have been flagged as
AES-CBC, since the crypto mode defaults to AES-CTR.
The fix is to not validate the crypto mode on unencrypted decrypt calls,
as the data won't be getting decrypted anyway.

This CL updates the unit tests to verify that
OEMCrypto_Generic_Encrypt and OEMCrypto_Generic_Decrypt can handle a
buffer size of at least 100k. It also adds code to the
oemcrypto_dynamic_adapter so that buffer sizes that are larger than
100k are broken into chunks of 100k.

Widevine request_license_tests were written with the expectation that
devices would by default be enabled for security level 1 and fallback
to level 3 if needed. Some devices such as seed are L3 only and results
in failures in the QueryStatusL3 test. This CL corrects the test's
expectation.

When processing a license or renewal, calls to Set/UpdateLicense
update the policy information. A side effect was introduced whereby
updating the policy may cause (expiration, session key state)
notifications to be sent to the listener. Due to the ordering,
the notifications would be sent before the keys were loaded/refreshed,
which caused issues when the notifications were immediately acted upon.
This has now been corrected.

When the Crypto API was updated, several unit tests were removed, as
they did not work with the new API. This patch restores those tests.
Note that this does not add NEW tests for the new functionality
enabled by the API changes. Those will be coming in a separate patch.
This patch merely restores the previous tests and their functionality.

updates tests/Android.mk to no longer try to build the private gMock.)
Previously, we maintained our own version of gMock (named libwvgmock
to avoid naming conflicts) and depended on it for our unit tests. Now
that Android has gMock in the externals/ directory and vaage@ has
eliminated the need for us to customize gMock's arity, we can stop
depending on or maintaining our own copy.

Sleep was being employed, to introduce a delay so that one license expired
but the other was still active. The duration was long enough that
occasionally the second license would also expire, causing the test to fail.
Reduce the sleep duration to correct this behaviour.

Some decryption errors were being reported as
vendor-unique diagnostic codes that were not generally
actionable by an app. Recently a new
MediaCodec.CryptoException code was added so these types
of failures can be reported as ERROR_UNSUPPORTED_OPERATION,
in which case the app can use an alternate DRM
configuration in a way that does not require
vendor-specific handling. This change remaps this class
of decrypt errors to the new error code.

* Protection scheme was not set in the WidevineCencHeader proto.
* HLS initialization data should be sent as a CENC content identification

An alternate scenario to renewing keys is to load the same keys in
a separate session and make use of them by using the session sharing
feature.
Session sharing involves iterating through a map of sessions and
returning the first session that contains the Key ID. In certain cases
(license about to expire) we might prefer an alternate session
be chosen.
Licenses may expire in two ways. Policy engine, driven by a 1 second
timer may detect expiry and send an asynchronous event. OEMCrypto may
also detect expiry based on information in the key control block
and return an error during decryption. It is possible that these
may differ by upto a second. This can lead to issues where decryption
fails but EVENT_KEY_EXPIRED is not generated till later.
It is possible to address this by using information from both timers
to notify the app about expiry. To implement this correctly will
add complexity and require synchronization between threads. To avoid
this an alternate solution is, if session sharing is used, to pick
the session that has a license with the longest remaining validity.
