There is an OEMCrypto wrapper that loads the OEM provided library.
For debugging and initial implementation, this only verified that some
of the API existed before continuing.
With this CL, the level 1 library is not used if any of the API
functions are missing, or if the version number is not correct. There
is no plan to make this library backwards compatible.

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
