Merge from Widevine repo of http://go/wvgerrit/24729
This CL adds a new variant of the OEMCrypto mock code that adjusts its
behaviour based on a configuration file. This is intended for
testing.
For example, a tester can set current_hdcp to 2 in the options.txt
file, push it to the device, and verify that a license is granted for
HDCP 2.0. Then the tester can edit the value of current_hdcp to 1 and
push the file to the device. Playback should stop because the license
is no longer valid.
This variant uses a real level 1 liboemcrypto.so to push data to a
secure buffer. That means we can test playback for a license that
requires secure buffers on an Android device with real secure buffers.
