20fc54e384 Add client information to release and renewal messages
[ Merge of go/wvgerrit/14240 ]

Client information is reported in release and renewal messages based on
flag in the license. License proto has been updated to match server updates.

There are two caveats
* Client IDs will be reported unencrypted when usage reports are requested.
* Release requests that enable privacy mode (encrypted client IDs) but do not
  specify a service certificate are not supported.

59811eed57 Support Per-Origin Provisioning
This is a merge of several Widevine-side commits that, cumulatively,
allow callers to specify an origin to be used to isolate data storage
as specified in the W3C Encrypted Media Extension specification.
Separate origins have separate certificates, and consequently cannot
share device identifiers with each other.

The changes included in this are:

Add Ability to Check for Existing Certificates
    http://go/wvgerrit/13974
Add Ability to Remove the Certificate
    http://go/wvgerrit/13975
Make CDM Origin-Aware
    http://go/wvgerrit/13977
Add Per-Origin Storage to Widevine CDM on Android

69a9f8edb2 Change DeviceFiles Helpers to Accept std::string
(This is a merge of http://go/wvgerrit/13922 from the Widevine CDM
repository.)

I'm not sure why we chose to pass char* instead of std::string to the
helper functions in DeviceFiles, but it seems to require a lot of
gymnastics of the calling code for minimal gain.

c66badec60 Add More Base Path Helpers to DeviceFiles
(This is a merge of http://go/wvgerrit/13910/ from the Widevine CDM
repository.)

DeviceFiles has a lot of repeated code whenever it needs to check for
file existence or remove a file. When reading and writing files, it
has wrappers that handle this repeated burden. This change adds
wrappers for the other functionality used by DeviceFiles as well, to
reduce duplication.

d2ba3a3f91 Allow selective removal of Usage Table Entries by PST
This is a merge of http://go/wvgerrit/13693 in the Widevine
repository.

This adds level 3 and mock implementation and unit tests for the
OEMCrypto function OEMCrypto_ForceDeleteUsageEntry.  It also plumbs
this function up into CdmEngine, CdmSession, and CryptoSession so that
deleting all usage information for a given app id will now delete the
entries in OEMCrypto, too.

a3b0d83d19 Run clang-format on Core
This copies over formatting changes from the Widevine CDM repository
that resulted from running clang-format with Google style on the
shared core/ directory. It also copies over some rewordings of log
messages that were made at the same time.

Aside from the changed log messages, this should not affect behavior
or functionality.

620b05dba0 Generate Key Set IDs at Key Request Generation Time
(This is a merge of http://go/wvgerrit/11285 from the Widevine CDM
repository.)

The key set ID is now available earlier, in order to support the CE
CDM 4.5 interface, which needs it at key request generation time, not
later at key response receipt time. It is still possible to receive
the key set ID at key response time, for Android's purposes. Either
API may now be passed a pointer to store the ID in, which may also be
left NULL if this is not needed.

aa7ad630d7 MediaDrm throws an exception when Secure Stops are requested
Our recommendation to OEMs is that they support a table of at least 50
usage entries in OEMCrypto. If more usage entries are stored, the PSTs get
added to the CDM but are LRU'ed out of the OEMCrypto usage table. When the
CDM queries those usage entries, OEMCrypto will return a
OEMCrypto_ERROR_INVALID_CONTEXT. Rather than return an error and have
MediaDrm throw an exception, CDM should delete this PST and return the
next usage entry, when queried.

4819a26bd4 Fixes for query information and usage reporting
* The Usage APIs return usage reports from either L1 or L3 (if available).
* Correction to when usage reports are saved. In addition to other events
  they are now saved when keys are loaded, usage reports are released and soon
  after first decryption and periodically (60 seconds) after that,
  if decryption takes place.
* Usage reports now get deleted on an unprovision request.
* Policy timer is now started when offline licenses are restored.
* Usage session is now released, when a usage response is received.
* Usage tests ahev been enabled.
* Added CDM extended duration (integration) tests to test usage reporting
  and querying. These need to be run manually as they take a while (currently
  half an hour).

[ Merge from Widevine CDM repo of
  https://widevine-internal-review.googlesource.com/#/c/10171/ and
  https://widevine-internal-review.googlesource.com/#/c/10172/ ]

Updated license_protocol.proto from constituent protos in google3

These changes make use of OEMCrypto v9 changes to support usage reporting.
Usage reporting may be enabled for streaming (by means of secure stops) and
offline playback by a provider session token specified in the license.

Changes include periodically updating usage information for relevant
sessions and reporting and releasing usage information as needed.

The CDM has removed all references to Secure Stops. This change
updates the Android API implementation to comply.

f6c2a60485 Allow Apps to Voluntarily Downgrade to L3 Crypto
This merges the following changes from the Widevine CDM repository:

564f4cc  Add CdmClientPropertySet to CDM
  Adds an interface to the CDM that allows it to query its client for
  certain properties.  In this case, this includes the ability to
  specify what security level is desired, as well as support for
  service ceritifcate privacy mode.

9cfbd3e  Force Level 3 fallback
  Adds support for voluntarily invoking L3 crypto to the OEMCrypto
  wrapper.

95d12c1  Add pointer to CdmClientPropertySet class to OpenSession.
  Adds support for storing the property set on a session-by-session
  basis and choosing the appropriate crypto level.

17de442  Add Settable Properties for Clank to Android
  Adds support for setting the aforementioned properties to the
  DrmEngine

bbe704d  Fixes to force fallback to level three security
  Corrections to invoke provisioning, OEMCrypto API with configured
  security level rather than the default. Unit tests were also revised.

Note that some parts of this are also support for the ability to use
a service certificate-based privacy mode. The remaining code for
supporting this mode is still forthcoming.
