Alex Dale 78f4bca3a9 Restrict reserved Client ID fields.
[ Merge of http://go/wvgerrit/108904 ]

Client ID name-value fields in the license request share the same
namespace with app parameters and WV standard device information.  As
a result, it was possible for applications to provide parameters that
could potentially fool the license server with spoof values.

This CL restricts the use of the fields that are common across both the
Android CDM and CE CDM.  Currently, Android specific fields are
restricted by the MediaDrmPlugin layer, and there are no CE CDM
specific fields currently defined.

The non-HIDL DRM plugin does not restrict these fields; however, it
will be removed in S.

Bug: 171723566
Test: Android integration test

This is the source code for the Widevine Content Decryption Module (CDM) for the
Android OS.  It provides the libwvdrmengine plugin for DRM.

Partners who are integrating a device should be familiar with the documents in
the docs directory.

This source code is NOT open source, and is not part of AOSP.  However, it is
released to partners external to Google after official Android releases.  For
this reason, partners should look for bug fixes and software updates on the
widevine branches:
