History
Matt Feddersen a2a27c44ef Correctly parse v18.0 provisioning requests 
The previous code fixed a backwards compatibility error for v18 provisioning requests being parsed by a v17 or older server. This bumped the minor version number to v18.1. v17 servers are still expected to fail when trying to parse v18.0 provisioning requests, and v18.1 requests will pass.

However, it did not correctly account for existing v18.0 requests on v18.1+ servers. v18.0 messages were naively detected by a failure to parse, and the parse function was not run again. This left the resulting nonce and session_id values uninitialized.

This CL fixes that by explicitly handling the v18.0 and v18.1+ cases, ensuring that the parse function succeeds and all relevant information is copied over. Furthermore, the unit test that was meant to catch this edge case has been improved to validate the resulting parsed message.

All code changes affect the server. This does not affect the client code eg OEMCrypto

README 

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:
