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.

In OEMCrypto V13, usage table header and usage entries are stored in
persistent non-secure storage and loaded and unloaded from the TEE.
Information needs to be maintained to assist finding the associated license
or usage information. This information has been revised for usage information
to use key set id and usage info file name rather than provider session
token and app id.
The app id is stored in a hashed form (usage info file name) and was not
extractable during the upgrade process to OEMCrypto V13. Due to this
DeviceFiles UsageInfo routines have switched to use usage info file name
rather than app id as a key.

When using the grace period, the CDM will need to override the values
given to use by the TEE (through OEMCrypto). Normally the first (and
last) decrypt times are stored securely by the TEE. To avoid extra

by the TEE when using this feature.

This CL refactors some oemcrypto unit tests in preparation for adding
Provisioning 3.0 tests.
- The signature GenerateNonce has changed. Instead of the caller
passing in a pointer for the nonce, we store the nonce in a member
variable of Session.
- GenerateDerivedKeys is being replaced by InstallTestSessionKeys.
This sets up and calls the appropriate derive keys method. This
function is in the test class, instead of the session class so that
multiple sessions in a class can share the same wrapped rsa key.
This will be modified for provisioning 3.0 in a future CL.
- Rename tests that require a keybox. Some tests are specific for
using a keybox to request a DRM cert. These tests are renamed so we
can filter them out on devices that use an OEM Cert. Corresponding
tests for devices using provisioning 3.0 will be in a future CL.
- Some member variables and methods in the class Session were not
used. They are removed.
- Added openssl smart pointer.
- Comments. I added comments.
- clang format.

Protections schemes are specified using a 4CC code {"cbc1", "cbcs",

PSSH was created and inserted into the license request. A reverse
conversion was performed when the code was extracted from the

These conversions are problematic if the PSSH is created externally and
passed into mediaDrm. To address this, the conversions have been removed
and allow protobuf to handle byte ordering. For backward compatibility
we allow codes in either ordering.

* Cdm Session and Engine interface clean up
[ Merge of http://go/wvgerrit/16387 ]
Key Set Ids have been removed from the CdmSession interface
(GenerateKeyRequest, Addkey) as they can be queried by an accessor.
The CdmEngine interface now allows one to specify or retrieve a session ID,

returned though GenerateKeyRequest as they was not being used.
* Generate key set ID when session is initialized
[ Merge of http://go/wvgerrit/16370 ]
Key set IDs are currently generated at different times in the
CdmSession lifecycle. Android generates key set IDs when the license
is received, while the CE CDM generates (or overrides them)
when the session is constructed.
The key set IDs are now generated when the session is initialized.
Key set generation cannot occur earlier as it has a dependency on
security level and in turn on crypto session initialization which
occurs when the session is initialized.
Depenencies on Session ID has caused other activities, construction of
PolicyEngine, CdmLicense, setting property CDM client sets to be
deferred from CdmSession constructor to Init().
Android will still retrieve the key set IDs after the offline license is
processed. For streaming requests, the key set will be
unreserved and discarded when the session is terminated.
