b2af1e6303 OEMCrypto Version 9 API (KLP Modular Version)
This CL changes the header file and documentation for OEMCrypto
version 9.

It is a cherry pick of Change-Id: I1a43a686ef5d345132affc672bc1c6acf7b3f661

I modified the reference implementation and the calling functions just
enough that existing unit tests still pass.  Acutal implementation of this
API will be in future CLs.

Comments on the documentation can be made in the Google Doc here:

67c794bac3 Add unit test for empty mac key
Merge of change https://widevine-internal-review.googlesource.com/7950.

In the OEMCrypto library, it is valid to call LoadKeys with an empty
mac key.  The library should not update the mac and enc keys and
should not throw an error.

Since we have seen this behavior in several implementations, a unit
test should be added that verifies the correct behavior.

0ab663d8a5 Rename Unit Test
In order to run all disabled OEMCrypto unit tests with one gtest
filter, one of them needs to be renamed so it matches the others.

These tests are disabled by default because they install a test
keybox, which would be dangerous on a production device.

0190f99fb3 Migration from jb-mr2 to master for Widevine CDM
Android development of the widevine CDM has been done
on the jb-mr2 branch of the cdm code base.  This CL
contains a merge of that jb-mr2 work to CDM master, and
also reflects the evolution of the common Modular DRM
code base since jb-mr2 branched.

5d7ac644c5 Disable OEMCrypto tests that install a test keybox.
Because we do not want to accidentally install a test keybox on a
production device, most of the oemcrypto unit tests are being disabled
by default.

If you wish to run these tests, you can override this choice, by
running:
adb shell /system/bin/oemcrypto_test --gtest_also_run_disabled_tests

This change prompts for and requires positive confirmation before
running the disabled tests on a device that has a non-test keybox
already installed.

15cf441d17 Fix RefreshKey Test
The test for refresh keys with a stale nonce was not performed
correctly.  It was supposed to test that RefreshKeys fails when the
nonce is stale.  However, the nonce in the test was not stale. The reference
implementation did fail, but it failed because the control bits were
in network byte order instead of host byte order.  Both of these
problems are fixed in this CL.
This CL changes test code only.  The change has already been
communicated with Qualcomm.
