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.

[ Merge from go/wvgerrit/22920 ]
Automated tests reveal a race condition between closing
a session and the periodic policy timer event. If a close
session was in progress (WVDrmPlugin::closeSession) and
CdmEngine::CloseSession caused the CdmEngine::session_list_lock_
to be held, a call into CdmEngine::OnTimerEvent would pend on the
release of the lock.
The close session would continue to deallocate the session
and disable (stop) the policy timer leaving the CdmEngine::OnTimerEvent
call in an undefined state. This would result in an ANR.
This subtle race-condition was introduced when changes were made
to add in per-origin storage [ http://go/wvgerrit/17971 ]. This seems
to happen at a low frequency (~ < 0.5%).

This is a merge of squashed CLs.
* Cdm Session and Engine interface clean up
[ Merge of http://go/wvgerrit/16387 ]
Key Set Ids have been removed from the CdmSession interface
(GenerateKeyRequest, Addkey) as they can be queried by an accessor.
The CdmEngine interface now allows one to specify or retrieve a session ID,
since both were not being used in a single call. Key set IDs are no longer
returned though GenerateKeyRequest as they was not being used.
* Generate key set ID when session is initialized
[ Merge of http://go/wvgerrit/16370 ]
Key set IDs are currently generated at different times in the
CdmSession lifecycle. Android generates key set IDs when the license
is received, while the CE CDM generates (or overrides them)
when the session is constructed.
The key set IDs are now generated when the session is initialized.
Key set generation cannot occur earlier as it has a dependency on
security level and in turn on crypto session initialization which
occurs when the session is initialized.
Depenencies on Session ID has caused other activities, construction of
PolicyEngine, CdmLicense, setting property CDM client sets to be
deferred from CdmSession constructor to Init().
Android will still retrieve the key set IDs after the offline license is
processed. For streaming requests, the key set will be
unreserved and discarded when the session is terminated.

* Reject session clobbering.
[ Merge of http://go/wvgerrit/14634 ]
This fixes a bug in I17de92b3e682c9c731f755e69466bdae7f560393 in which
sessions can be clobbered by a forced session ID. This bug manifested
in subtle test failures which involved repeatedly creating sessions.
This was traced to OEMCrypto not being terminated, then upward to a
leaked CryptoSession and CdmSession, and then finally to clobbered
session IDs.
To avoid the bug in future, first, reject duplicate session IDs.
Second, change the OpenSession API to make forced IDs explicit.
* Fix unit test namespaces.
[ Merge of http://go/wvgerrit/14622 ]
This fixes some odd errors that occur when linking multiple test
suites into one executable. When two object files both contain
a definition of wvcdm::MockCryptoSession, for example, one will win
silently and cause the other's tests to misbehave and/or crash.
The solution is to put all mocks into an anonymous namespace, since
each wvcdm::(anonymous)::MockCryptoSession is separate.
In order to avoid lots of repetitions of wvcdm:: in the anonymous
namespaces, all anonymous namespaces in unit tests now live inside
or the wvcdm namespace. This has been done even for tests which
are not currently using mocks.

* Account for backward compat support in tests

One test ensures that device path backward compatibility is working,
while another assumes it is used.
This fixes test results when
Properties::security_level_path_backward_compatibility_support()
is false.
Previously, the CE CDM did not run these tests, and so this went
unnoticed.

* Add Properties::AlwaysUseKeySetIds().
When true, all sessions will have key set IDs and all session IDs

only have a single, random ID used for both streaming and offline.

support was added to the core to report if a session ID is valid.

Removes the OS Version property which was only ever implemented on
Android to appease Netflix and never actually used by them. Adds,
instead, a Widevine library version property. Also adds

reflect that this is the third major revision of the Widevine CDM in
Android.
For CE Devices, the version number is not changing from its current
value (2.2.0) but is gaining a "-ce" on the end in order to
differentiate it from the Android version number.

This cleans up our includes to be in Google Style Guide order and in
alphabetic order, for the parts of the code that are expected to
follow Google Style.
This also converts places in our code that were including C headers
in the C++ style (i.e. <cstring> instead of <string.h>) to use C style
instead. This is because, although it was not causing problems for us
yet, on Android these actually include different headers. (<cstring>
is provided by libcxx, while <string.h> is provided by Bionic)
Lastly, this change puts all headers that do not come from within our
project in <brackets> instead of "quotes," which was not being done
consistently.
This change is explicitly NOT trying to standardize the spacing of our
header includes. I have tried to respect, in each file, the spacing
style already present.

Netflix reported that after pulling power while their app is active,
the app isn't able to restart. This is because the license file for
session keys isn't getting synched to disk, so the data is still in
the buffer cache when the device shuts down. Calling fflush and fsync
on the file ensures the data is persisted to disk. fclose alone
doesn't do fsync.
In testing, I also noticed that the license file was being rewritten
every second which is hard on the flash filesystem. The timer thread
was modified to avoid these frequent writes.

When falling back to L3, release requests were failing. Information
requesting falling back to L3 is passed along when the session is opened.
Licenses however are released using the key set ID and information
requesting fallback to L3(CdmClientPropertySet) at that point is
unavailable. The release was actually attempting to release a license
at the default security level which is incorrect.
In addition, the mac keys were not being setup correctly and the release
message was signed with keys derived from the license request and not the
response. Both these issues have been addressed and unit tests added
to track release of offline licenses and usage reporting scenarios.

This change updates the CDM's handling of init data types, previously
known as MIME types, to comply with the latest version of the EME
spec.
Following this change, in addition to accepting the deprecated MIME
types "video/mp4", "audio/mp4", "video/webm", and "audio/webm", the
CDM will accept the new standard: Init data types "cenc" and "webm".
Furthermore, this removes the non-PSSH-parsing path from the CDM. All
platforms have unified on the CDM being responsible for parsing the
concatenated PSSH box list, as outlined in the latest EME spec.
As Android has shipped code that expects pre-unwrapped PSSH boxes and
must maintain backwards-compatibility, code has been inserted on that
platform to detect pre-unwrapped data and re-wrap it with a PSSH
header before sending it to the CDM.
There are some small changes to unit tests because of this change:
1) The CDM Engine unit test now no longer needs to unwrap the PSSH on
any platforms when testing ISO-BMFF. It now pre-caches the
unwrapped key ID for use when testing WebM.
2) Several substantially-similar unit tests in the Android code have
been rolled into one test.
