853773dd93 Build widevine tests with BOARD_VNDK_VERSION set
The tests are using vendor only libs such as libcdm and libwvlevel3,
thus marked as LOCAL_PROPRIETARY_MODULE to use the libs. In addition,
the dependency to libmedia is changed to libmedia_omx since libmedia is
not available to vendor modules. UniquePtr is replaced with
std::unique_ptr since UniquePtr.h in /libnativehelper is not available
to vendors (and will not be completely removed in a near future).

43b8522b70 Pass CdmIdentifier to UsageInfo Methods
The methods on WvContentDecryptionModule related to UsageInfo (Secure
Stops) do not work if kDefaultCdmIdentifier has not been provisioned.
This can occur if an app provisions and uses an origin without any app
on that device ever provisioning the default origin. More concerningly,
this will happen 100% of the time on SPOID-using devices, as there is no
way to provision the default identifier on these devices.

The fix is to pass the current identifier to these methods so that they
do not have to use kDefaultCdmIdentifier.

c0a7655834 Maxing Out Sessions Can Cause SPOID Failures
(This is a merge of http://go/wvgerrit/25581)

To prevent dead DRM Plugins from being instantiated when there are no
sessions available, the time at which the device ID is queried has been
moved from instantiation-time to SPOID-calculation-time.

SPOIDs can now fail to be generated. Which means anything that depends
on a SPOID may fail because of this. However, this is a more actionable
problem for apps than having them receive a dead or unusable DRM Plugin
object.

19947dfe6f Move SPOID Enable/Disable Logic Out of WVDrmPlugin
(This is a merge of http://go/wvgerrit/25580)

While writing fixes for b/36660726, b/34716264, and b/36065223, it
became clear that having the logic that checks whether the device
supports SPOIDs embedded inside WVDrmPlugin was complicating its code
and inhibiting testing of the class. By moving this check into the code
that instantiates WVDrmPlugin, the result of the calculation can be
independently tested while the tests for WVDrmPlugin can put it in
whatever state they need for the sake of unit testing.

As a consequence of this, the check on retrieving the "deviceUniqueId"
byte array property, which was removed when SPOIDs were implemented, can
be reinstated.

f2463075ac Fix & Improve Test-Building and -Running Scripts
(This is a merge of wvgerrit/24922)

This contains several fixes and improvements to the
build_and_run_all_unit_tests.sh and run_all_unit_tests.sh scripts:

* All tests are now identified as vendor binaries and thus are stored in
  the /vendor/bin/ directory instead of /system/bin/. Previously, some
  tests had moved to /vendor/bin/ but the scripts had not been updated,
  causing these tests to fail to run.
* The -j parameter can now be passed to build_and_run_all_unit_tests.sh,
  for those who want to speed up their build by using multiple cores.
* The 64-bit library directories are now added to the library search
  path, in anticipation of devices with 64-bit DRM Plugins.
* Checking for Verity protection is now done in
  build_and_run_all_unit_tests.sh (which is the script that actually
  modifies the file system) instead of just in run_all_unit_tests.sh.
* The library search path is no longer set unnecessarily for
  libwvdrmengine_hidl_test.
* The Treble-only tests and non-Treble-only tests now only run on
  devices that meet their respective criteria.

bfe6046199 Build Android Unit Tests 32-bit Only
(This is a merge of http://go/wvgerrit/24738)

The change to enable 64-bit as a possible target for Widevine Android
made all the unit tests build as 64-bit on compatible platforms. Since
none of these devices support 64-bit properly yet, this is a mistake.
This patch restores unit test builds to being 32-bit only for now.

In the future, when the switch for 64-bit-supporting devices is added,
it will also switch the unit tests to 64-bit mode.

d9b90be205 Enable SPOIDs in Treble Widevine Glue Layer
Adds code to the Widevine Glue Layer that drives the generation and use
of SPOIDs on platforms that support SPOIDs. (All devices whose first
release is Android O or later.) Note that this only applies to the new,
Treble-ized API. If the Widevine DRM Plugin is accessed through the old
API, it will not use SPOIDs. This is by design because the old API does
not provide an application package name, so SPOID generation is no
better than the existing, origin-based solution.

df0dad5311 Enable 64-bit Android Builds
(This is a merge of go/wvgerrit/23686)

This patch removes the makefile lines that previously prevented the
Widevine DRM Plugin from being built as 64-bit on Android. 64-bit
builds are now fully supported.

Only one piece of CDM code has had to change. Due to a bug in
libprotobuf before v3.0, int64 values from protobufs are technically a
different type from int64_t values in code on some 64-bit
architectures. Both have the same in-memory representation at runtime
but are seen as distinct types by the compiler. The compiler will
automatically convert in most places, but template instantiation is
not one of them, so a few places that passed a Protobuf int64 directly
into a template had to be modified.

Please note that tweaks to the mediadrmserver (not covered by this
patch) are needed in order for it to run as 64-bit and load 64-bit DRM
Plugins. Please also note that, as we have no 64-bit L1 OEMCrypto on
any devices, using the 64-bit mediadrmserver and Widevine library will
make your device fall back to L3 for the time being.

c85351682f SPOID
(This is a merge of go/wvgerrit/23182)

This patch adds the framework for Stable Per-Origin Identifiers to the
CDM. Calculating SPOIDs will be done on the client-side, and they are
sent as part of the provisioning request. SPOIDs are also available to
the app as the Device Unique ID, replacing the previous method of
returning the actual Device Unique ID from the keybox / OEM certificate.

Different SPOIDs must use separate storage, just as different origins
already do. Support for this has been added to the Android adapter to the
CDM Core. However, the code in the Android glue layer that would drive
this behavior will be checked in in a separate change. As such, all
Android devices will continue using the legacy behavior even after this
patch goes in, until the glue layer code can be updated.

Added a fix to include all key Ids in the WidevineCencHeader rather than
just the first. Also modified the content_id to reflect that it is a
base64 encoded value.

e5dfb83e03 Improve query performance
[ Merge of http://go/wvgerrit/15780 ]

Android mediaDrm allows callers to serially query status information through a
property API. CDM however retrieves all status information in a map and
filters out all but the relevent one. This leads to delays in Netflix app
startup. Rewriting the CDM interface to return only the queried value.

8443abc555 Re-Add MIPS to Android CDM Build
(This is a merge of http://go/wvgerrit/14795)

This change restores the ability to build the Widevine CDM for Android
for MIPS devices. It restores the precompiled binaries for MIPS and
re-adds MIPS to all makefiles.

This change includes a new build of the obfuscated binaries for
MIPS32r1 that were built using a MIPS device on the emulator.

89682556ad Fix CanSetServiceCertificate Test
(This is a merge of http://go/wvgerrit/14783)

When validation was added to the service certificate property, it
broke the associated test, which sends random data. It also did not
do any testing of the new validation itself.

This fix makes the validation method on WvContentDecryptionModule
non-static so that it can be mocked and handled appropriately in the
test.

Merge from widevine repo of http://go/wvgerrit/14742

The CDM object can no longer be created on the stack because it
inherits from RefBase.  This caused some unit tests to hang in the
MockCDM destructor.
