0b02296014 Removing Non-HIDL Widevine DRM Plugin for Android
[ Merge of http://go/wvgerrit/138089 ]

Non-hidl code is no longer needed in the widevine android plugin. By
doing work this cleanup will save the team from having to keep
maintaining code that isn't needed anymore.
Clean up steps taken as follows:
    1. Remove non-hidl code but keep commonly used code
    2. Remove legacy test code
    3. Remove legacy test build and test entry

a8328dd2f9 Delete Singleton on Library Unload
(This is a merge of http://go/wvgerrit/14531)

As an optimization, the Media Server now unloads our library when not
in use. This has exposed a bug by which we were never deleting the CDM
singleton. Fix is to make WvContentDecryptionModule an Android smart
pointer ref base and then make sure all the plugins store a strong
pointer to it. The singleton is a weak pointer, so when the last
plugin is cleaned up, the CDM will be as well. And on the off chance
that the library isn't immediately unloaded, the singleton code will
generate a new CDM next time one is needed.

0540770280 Remove Backwards-Compatibility for Classic MediaCodec Mode
(This is a merge of http://go/wvgerrit/14082)

Previously, the CryptoFactory had special behavior to defer creation
to Widevine Classic if no session ID was provided. This functionality
has been deprecated, as MediaCodec Mode is no longer supported.

This is necessary as part of supporting the new API for session ID
changes because the expectation is that it is now legal to initialize
a modular CryptoPlugin without a session ID.

4b8dd050bf Downgrade Non-Critical Errors to Warnings
We are getting a lot of noise from Android bug-filers who are
concerned about several non-critical errors that show up when using
Widevine CDM on some devices or in some use cases. To mitigate this,
we are downgrading these errors to warnings.

Some of these errors pertained to our legacy support. To make sure
an error IS logged if problems with legacy support become critical,
a new error has been added to that code path.

951f08c2da Support Latest Version of EME Spec Init Data Specification
(This is a merge of
https://widevine-internal-review.googlesource.com/9711 from the
Widevine CDM repo.)

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.

7eea20df86 Add Support for Audio MIME Types
The EME spec technically requires CDMs to treat audio/mp4 and
video/mp4 equivalently, as well as audio/webm and video/webm. We had
only been accepting video/mp4 and video/webm up until now.

This change also centralizes handling of init data types in the shared
CDM code instead of having it spread across multiple places in the
codebase.

702aadf853 Add Support for WebM Back
Adds support for WebM to the CDM. Decryption remains untouched,
however the initialization data is passed differently for WebM.

The previous version of this change broke playback for certain
apps that were being allowed to pass invalid MIME types before
this change was made. This version maintains backwards-compatiblity
for these apps for now by rewriting their MIME types as "video/mp4".
