* Corrects usage_table_header lifetime management. Earlier the
UsageTableHeader class was a singleton tied to the CdmEngine lifetime.
With SPOIDs there might be multiple concurrent CdmEngine objects.
The UsageTableHeader class is now associated with OEMCrypto
lifetime. There are two UsageTableHeader objects one for each L1 and L3.
These get allocated/deallocated on OEMCrypto Initialization/Termination
respectively.
* UsageTableHeader requires OEMCrypto, file read/writes and
metric gathering to perform its required functionality. Because of the
lifetime changes, CryptoSession, DeviceFiles and MetricsGroup objects
need to passed to the methods rather than at Creation time.
* Miscellaneous fixes, when moving or deleteing entries.
* Adds usage_table_header_unittests.
* Addresses failures with request_license_test with secure stop in L3.

These tests verify whether a L3 device respects the HDCP policy set in the
license request. L3 device should only play the clear lead, and stop at
encrypted content. MeidaDrm should throw an ERROR_INSUFFICIENT_OUTPUT_PROTECTION
exception. This is because L3 device always returns current HDCP connection
status as HDCP_NONE.
This CL modifies the policy engine CanDecryptContent method to return
CdmResponseType instead of a boolean, so the app can generate the correct
error response if HDCP constriants are not met.

Provisioning 3.0 devices that do not use SPOIDs have been returning
their full OEM Public Certificate as their device ID. While this is not
a security concern, (it is a PUBLIC cert) the cert is many times larger
than applications are likely expecting. (several kilobytes vs. just a
few bytes) This patch hashes the OEM Public Certificate to produce a
smaller value, but only when it is being provided out of the CDM to a
caller.

OEMCrypto_UpdateUsageEntry. In previous versions calls were made to
OEMCrypto_UpdateUsageTable instead. Both need to be supported as the
OEMCrypto version may vary by device.

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.

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.

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
