The top level makefile will build license_protocol_protos.a, which is
needed by libcdm.a. Unit and end-to-end tests are now build separately
under cdm/test.
Also, the tests use Google C++ Testing Framework, so please build the
gtest library from external/gtest and run "mm" once before building
the tests.
Or just run "mmma vendor/widevine/libwvdrmengine" (or mma in
vendor/widevine/libwvdrmengine") once.

Builds libwvmdrmengine.so, which is loaded by the new
MediaDrm APIs to support playback of Widevine/CENC
protected content.

Remove the clear key drm engine as it is no longer needed and
would need to be reworked to be compatible with the new MediaDrm APIs.

In order to match the other implementations of CDM, we are going
to replace the android OEMCrypto mockup with the one in the cdm
repository.
This would be disruptive to the clear key library because it
relies on the current implementation of the mockup. In order to
prevent that, I am moving the current mockup into the same directory
as the clear key library. Then, we can put the new mockup under
the directory libwvdrmengine.
This mockup will then be deleted when the clear key library is deleted.

Because the Widevine Sample Play is frequently used to report bugs, it is
helpful to have users' actions logged. This change prints to the android log
whenever the user changes settings, clicks play, full screen, acquire rights,
etc.
This code does not change the build and is not delivered to customers. It is
delivered to vendors.

This is a software only implementation of the OEMCrypto library for
testing the rest of the DRM code. It currently implements the
OEMCrypto_DecrtyptCTR function using a clear key.
I've included the license request code so the rest of the group can
play with it, but I have only tested part of it.
This patch also has some makefiles and an integration testing. You
should be able to generate the shared library libclearkeydrmengine.so with
cd vendor/widevine/libclearkeydrmengine; mm
You can create some unit test and integration test programs from the
directories:
vendor/widevine/libwvdrmengine/oemcrypto/test
vendor/widevine/libclearkeydrmengine/test
vendor/widevine/libclearkeydrmengine/inttest
vendor/widevine/libclearkeydrmengine/crypto/test
This change also addresses some comments about comments in OEMCryptoDASH.h
which were made in https://googleplex-android-review.googlesource.com/257323

Adds the initial pieces of a sample DRM Engine that accepts keys in the clear
through the decrypt call instead of using the DrmClientPlugin and its key
ladder. This is to help unblock teams writing code that consumes DRM Engines
while Widevine continues working their real DRM engine. This is based on the
in-progress Widevine DRM Engine.
This change contains the DRM Engine glue pieces (.so entry point,
DrmPluginFactory, etc.) and a CryptoPlugin implementation. However, said
CryptoPlugin will not work until an implementation of OEMCrypto is provided
in a future checkin and the CryptoPlugin is hooked up to it.
For ease of loading, this library also implements the old CryptoFactory
interface and entry point.
If asked to create a CryptoPlugin with no data, it will defer to the old
Widevine Crypto Plugin.

I added a few error codes for out-of-resource type conditions.
I added comments explain which functions may be called simultaneously.
Basically, info only functions, like getDeviceId, may be called anytime after
initialization. Functions that have a session parameter may be called at the
same time as other functions for a different session, but not for the same session.
Functions that create or delete sessions may not be called as the same time as any
each other, or at the same time as any session functions. The CDM is required to
honor these conventions.
If the OEM can only decrypt for one session at a time, it is the OEM's
responsibility to hold a lock.

The file OEMCrypto.h was renamed to OEMCryptoDASH.h and all
functions that are only needed for legacy support were removed.

I added a Mock OEMCrypto implementation with stubs only.
I corrected the "extern C" location in OEMCrypto.h. (Thanks, Jerry!)
I added some Android.mk files that allows us to compile and
run a few simple unit tests.
Unit Test 1: The library compiles. (passes)
Unit Test 2: The test program links and runs. (passes)

The solution previously checked in as 2e0e3 is re-introduced here. However,
the MediaCodec-compatible heuristic is not used unless WVM is in Crypto Plugin
(i.e. Media Codec) mode.
To repeat from last time: The problem here is that WVM cannot independently
seek the audio and video read heads, but the API assumes it can. WVM does the
right thing for AwesomePlayer-based playback (essentially ignoring audio
seeks) but the wrong thing for MediaCodec-based playback. For MediaCodec
mode, we should respect the first seek we get for a given destination and
ignore the second.
In this part, the new heuristic is reintroduced, but the old heuristic is
maintained for use in non-Crypto Plugin mode.
