Previously, extracting the system ID was only supported on Keybox-based
systems. This patch adds support for extracting the system ID from the
OEM Certificate chain on Provisioning 3.0 devices. This is done by
getting the Widevine intermediate cert from the chain, finding the
Widevine System ID extension in that cert, and extracting the value.
The code that does the extraction is separate from any code that calls
OEMCrypto so that it can be unit-tested in isolation. This patch adds a
crypto_session_unittest test to do this unit-testing.

Renames a few metrics for consistency with the logs processing module.
This CL changes the names of several metrics to be consistent with what
we use for the logs parsing module. E.g. for metrics consistency,
CdmSecurityLevel is referred to as "security_level" and SecurityLevel
is referred to as "requested_security_level".
The GetSecurityLevel method was modified to use CdmSecurityLevel instead

A vendor specific error (10008) in response to OEMCrypto_LoadKeys
indicates that usage table corruption has occurred and that
the only way to recover is to regenerate usage tables.
Recreating usage tables will result in loss of offline licenses
and usage information. To make the app aware that this information
will be lost, a provisioning exception is generated when this error
is detected. The app can then choose to reprovision and in turn
delete and recreate usage tables.
A new OEMCrypto error has been added whose use has been reserved.
Rather than correct OEMCrypto behaviour to use the new error code,
we choose to handle this within the CDM. The fix can then be ported
to prior android releases. Also this error will not be generated
with OEMCrypto V13+.

* Corrects usage_table_header lifetime management. Earlier the
UsageTableHeader class was a singleton tied to the CdmEngine lifetime.

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

* UsageTableHeader requires OEMCrypto, file read/writes and

Devices that use SPOIDs with keyboxes would expose the keybox's real

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

Starting with OEMCrypto v12, we are guaranteeing to integration partners
that the buffers passed to OEMCrypto_DecryptCENC and
OEMCrypto_CopyBuffer will not be more than 100KiB (102400 bytes) in
size. For requests larger than this, we will first try to send the
buffer to OEMCrypto anyway. (in case the integration supports buffers
larger than the minimum) In the event that the buffer is rejected, we
will break it up into 100KiB chunks and send them down individually for
decryption.
Breaking a subsample into smaller subsamples necessitates knowledge of
how to update other decryption parameters (like the offsets and the IV)
that previously the CDM Core has not needed to know about. Until now,
this knowledge lived in the glue layer on the Android CDM and nowhere
on the CE CDM. Now, the CryptoSession has a subset of this knowledge, in
order to break up buffers successfully.
For testing purposes, the Mock OEMCrypto has been modified to only
support the smallest buffer size. In order to make sure the chunking
code was being exercised by them, the CE CDM tests had to have the
amount of data they decrypt increased by several orders of magnitude. To
contain this growth, I have moved the test data to its own file.

similar test was attempted on Fugu but Fugu cannot pass these tests even

This patch removes the logic that calculates the "pattern offset" from
the Android glue layer. There is no such thing as a pattern offset, and
setting this value to anything other than zero may break cens mode on
some devices.
To reduce the risk of setting this value to anything other than zero,
the offset_blocks parameter has been removed from the pattern descriptor
in the CDM Core. It will have to remain part of OEMCrypto v11,
unfortunately, but the code to set it to zero is now centralized in
CryptoSession.
