582d3237c9 More Usage Table Tests
Merge from Widevine repo of http://go/wvgerrit/23865

This adds the following tests to the oemcrypto usage tables suite:
Forbid shrinking the usage table over open sessions.
Shrinking usage table must make it smaller, not larger.
Forbid creation of new usage table while open sessions using old.

826e390ad6 Consolidate update usage table calls
[ Merge of http://go/wvgerrit/23980 ]

In OEMCrypto version 13, usage information is updated by calls to
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.

This consolidates calls to OEMCrypto_UpdateUsageTable so that they
can be disabled if OEMCrypto version >= 13. No functional changes other
than disabling by OEMCrypto version were introduced in this section.

Helper routines have been added to device files as well.

0db3a137e9 Introduce UsageTableHeader class
[ Merge of http://go/wvgerrit/23820 ]

The UsageTableHeader class is a singleton that CDM sessions will share.
A separate object will be created for each security level. The class
synchronizes access to usage table header and associated data-structures
and controls when they are read in or written out to non-secure persistent
storage. Upgrades from a fixed size usage table (supported by previous
versions of the OEMCrypto API v9-12) are handled by this class.

e75d3a6512 Revise usage entry metadata
[ Merge of http://go/wvgerrit/23742 ]

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.

be448ed24a Collect Errors and Warnings In OEMCrypto Initialize
As a large number of provisioning errors can come from failures
initializing OEMCrypto we need to collect these  messages.
Errors and warnings were only printed to the log. This
change takes those messages and puts them into the oemcrypto
intialization mode metric.

"Mode" was chosen as most messages were about how oemcrypto
was initialized (e.g. into L3 because no L1 library was found).

Test: Ran all GTS Media Tests

ee5aff7706 Correct setting of service certificate.
[ Merge of http://go/wvgerrit/23380 ]

The service certificate was setup correctly if specified in mediadrm
properties. If instead the service certificate was later fetched from
the license service, it would not be marked as valid. This led to an
infinite loop of service certificate fetches and processing. This
prevented the license from being fetched and playback failures.

Still missing are: backwards compatibility, defragging the table,
haystack code, and lots of new unit tests.

The haystack now reports it doesn't support usage tables, so that
the unit tests will pass.  This will be fixed in a future CL.

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.
