functions
In CL https://widevine-internal-review.git.corp.google.com/c/cdm/+/183531
KDF was merged into new OEMCrypto_LoadLicense() and
OEMCrypto_LoadProvisioning().
This change renames L3 existing old functions with suffix _V18, and adds
the two new functions.
Note: jenkins/run_dynamic_level3 and jenkis/run_level3_static_tests
can't be enabled util https://b.corp.google.com/issues/320525541 is
resolved.
Test: the generated L3 from this CL can pass static and dynamic adapter
tests with commit ID 567069f2fb800c4ec4e844e03273d1924ae6673b. More
updates may be need to L3 source for it to work with the latest
oemcrypto-v19 branch.

Since the L3 functions are meant to alias the OEMCrypto functions,
they shouldn't appear in a namespace.

BCC supports two types of format: CBOR and X509. The latter will be
used by Chrome OS. In case of Prov4, BCC type will be queried by
OEMCrypto_GetBCCType() and the returned value is populated in the
provisioning request.
This CL adds X509 type to protobuf, a call from CDM to query BCC type
and OEMCrypto adapter changes for this call.

Also removed L3 function pointers to the function headers added in
go/wvgerrit/186010 because they weren't stubbed out and was causing the
new script to fail.

Since we want to migrate to using GTEST_SKIP to skip unit tests instead
of GTEST_FILTER, we can remove the RestrictFilter() function which
filters the tests out using GTEST_FILTER. To do this, the RSAPerformance
test needs to be removed, which is acceptable since no one uses this
test anymore. However, b/299135804 is being used to track a new way to
either execute/track permance.

Since KDF functions are only used right before specific functions, this
merges them to simplify internal state within OEMCrypto.

In v19, SetDecryptHash() was updated to only work with CRC-32.
While updating OEMCrypto, L1 (opk, intertrust, etc.) and L3, the
V18 version was not added to the dynamic adapter. This change
adds the backwards compatible call for L1s running V18 and earlier.

The current implementation of OEMCrypto_SetDecryptHash gives developers
flexibility to use different types of hashes. However, all the
implementations we have seen thus far use crc32. Because of this, crc32
should be sufficient and we can refactor OEMCrypto_SetDecryptHash to
only use the crc32 hash.

Creates parameterized certificate provisioning tests to prepare for DRM
reprovisioning implementation.
- Create parameterized certificate provisioning test suite.
- Change RETURN_IF_NOT_OPEN macro to call IsOpen instead of checking
the |open_| variable to make mocking of CryptoSession methods easier.

Creates new token types for the DRM reprovisioning scheme that will be
used by L3 CDMs with baked-in certificates to allow for use of unique
serial numbers.
- Create new `CdmClientTokenType` for DRM reprovisioning in the CDM
core.
- Create a new `ProvisioningType` for DRM reprovisioning in the
provisioning message proto.
- Create new enum value for `DEVICE_EMBEDDED` in DrmCertificate type.
- Update uses of the above to include the new token types.

to the new android ownership model. If you find incorrect or unnecessary

String obfuscation hides string literals from static analysis but
requires string literals be used inside protected functions.
- Enable string obfuscation for all function groups.
- Change some global `std::string` to `const char[]` to ensure that
the `std::string` is constructed inside a protected function so
that string obfuscation correctly applies to the string literal.

Flags are to be used in new tests when creating tests that potentially
take a long time to run. Certain test suites are intended to be quick
and may skip certain long running tests.
New slow tests should check these flags and skip using GTEST_SKIP().

"client_version" is an optional, information field in the protocol for
license requests. It was requested that the CE CDM includes this
information in the license request. It does not hurt to include this
information in the Android license requests too.
If, for some reason, the client cannot provide this information, the
request is still sent out as normal. No reason to prevent an otherwise
valid license request due to a missing optional field.
Note: This field is directly in the LicenseRequest message and not the
ClientIdentification message.

Devices may be revoked by the provisioning server resulting in an
error message contained within the provisioning response. The CDM
core currently returns an error, but the CE CDM would map this to
an kUnexpectedError, which does not provide the information to the
CE client to react. This situation is not immediately recoverable,
but may provide certain apps to use a different DRM plugin if they
support such a thing.
Documentation and tests are needed.

GetDeviceInformation() and GetDeviceSignedCsrPayload() are added to
cdm_engine and crypto_session, so that they can be queried by DRM
plugin. This is to allow the wv drm HAL to be able to extract BCC and
CSR payload to build CSR for prov 4 device registration, such that we
don't need a separate RKP HAL to do this job.
Changes to the DRM plugin to use the exposed methods will be in the
coming CL.
