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.

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.
