Alex Dale 1183ae813f Filter out key set IDs based on ATSC mode.
[ Partial cherry-pick of http://go/wvgerrit/185854 ]

Certain GTS tests do not fully consider restrictions on ATSC devices.
In particular, GTS assumes if there are any key set IDs returned to
the app via the MediaDrm API, then the device must already be
provisioned.  ATSC license are special in that they may be available,
but the CDM is not provisioned while outside of ATCS mode.

To work around this assumption made by GTS, we filter out ATSC licenses
returned by getOfflineLicenseKeySetIds() when the device is not in
ATSC mode, and filter out non-ATSC license when it is in ATSC mode.

This is only a soft enforcement mechanism as calling the API with a
valid ATSC license while outside ATSC mode (or a non-TSC license in
ATSC mode) will continue to result in the failures experienced by
certain OEMs.

This is the source code for the Widevine Content Decryption Module (CDM) for the
Android OS.  It provides the libwvdrmengine plugin for DRM.

Partners who are integrating a device should be familiar with the documents in
the docs directory.

This source code is NOT open source, and is not part of AOSP.  However, it is
released to partners external to Google after official Android releases.  For
this reason, partners should look for bug fixes and software updates on the
widevine branches:
