Merge from widevine repo of http://go/wvgerrit/17463
This CL updates the unit tests to verify that
OEMCrypto_Generic_Encrypt and OEMCrypto_Generic_Decrypt can handle a
buffer size of at least 100k. It also adds code to the
oemcrypto_dynamic_adapter so that buffer sizes that are larger than
100k are broken into chunks of 100k.
All Nexus devices targeted for N pass these tests.
