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

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.

This header file documents the interface of the ContentDecryptionModule
and the CDM client.

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)
