f6c2a60485 Allow Apps to Voluntarily Downgrade to L3 Crypto
This merges the following changes from the Widevine CDM repository:

564f4cc  Add CdmClientPropertySet to CDM
  Adds an interface to the CDM that allows it to query its client for
  certain properties.  In this case, this includes the ability to
  specify what security level is desired, as well as support for
  service ceritifcate privacy mode.

9cfbd3e  Force Level 3 fallback
  Adds support for voluntarily invoking L3 crypto to the OEMCrypto
  wrapper.

95d12c1  Add pointer to CdmClientPropertySet class to OpenSession.
  Adds support for storing the property set on a session-by-session
  basis and choosing the appropriate crypto level.

17de442  Add Settable Properties for Clank to Android
  Adds support for setting the aforementioned properties to the
  DrmEngine

bbe704d  Fixes to force fallback to level three security
  Corrections to invoke provisioning, OEMCrypto API with configured
  security level rather than the default. Unit tests were also revised.

Note that some parts of this are also support for the ability to use
a service certificate-based privacy mode. The remaining code for
supporting this mode is still forthcoming.

5fcfbca  Handle OEMCrypto_ERROR_INSUFFICIENT_RESOURCES on Decrypt
  Changes the CDM to support the new errors from the previous change.

d59c09d  Report Insufficient Crypto Resources
  Changes the DrmEngine to support the new errors from the previous
  change.

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.

36aeacde48 Optimize Status Queries in WVCryptoPlugin By Deleting Them
Removes the status query from WVCryptoPlugin's decrypt method.  It was not
providing any additional security since it was not cryptographically secure,
and querying status is an expensive operation on some devices.  It should not
be done on a frequent basis, such as in every decrypt call.

cd304b1c46 Use Standard Errors in DrmPlugin
Now that MediaErrors.h has errors for some of the conditions we were using
custom error codes for previously, we should switch to using the standard
error codes in order to get better error reporting to the app.

c1474b9912 Add Detail Error Messages
Reworks the error message reporting that was just added to WVCryptoPlugin so
that it reports detailed error messages to the app (because the error codes
cannot be relied upon to reach the app intact) and so that it always reports
custom errors so that the detailed error message is passed to the app.
