Add DecryptCTR to OEMCrypto Mock

Browse Source 
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
