These are a set of CLs merged from the wv cdm repo to the android repo.

* Resolve intermittent decrypt error.

  Author: Jeff Fore <jfore@google.com>

  [ Merge of http://go/wvgerrit/35720 ]

  The CdmSession's closed state was not properly
  initialized resulting in intermittent
  SESSION_NOT_FOUND_FOR_DECRYPT errors.

  In CdmEngine::Decrypt the session is looked up by
  the key id. A list of open sessions is acquired
  by calling CdmSessionMap::GetSessionList and each
  session in the list is queried to see if it has
  the key.

  In building the list in CdmSessionMap::GetSessionList,
  sessions are only added to the query list *if* the session
  is not closed.

  The closed status was not initialized and during testing
  the query list would not contain the session causing
  CdmEngine::Decrypt to return SESSION_NOT_FOUND_FOR_DECRYPT
  resulting in the ce cdm api returning widevine::Cdm::kNoKey.

* No support for pre- C++11 compilation.

  Author: Gene Morgan <gmorgan@google.com>

  [ Merge of http://go/wvgerrit/35381 ]

* Handle unaligned nonce pointer in RewrapDeviceRSAKey calls.

  Author: Gene Morgan <gmorgan@google.com>

  [ Merge of http://go/wvgerrit/35340 ]

  The pointer points into a message and it may not be aligned.
  Always copy the nonce into aligned memory before checking it.

  BUG: 38140370

  Add note to CHANGELOG for this.

* Compiler strictness: more checks and code cleanup.

  Author: Gene Morgan <gmorgan@google.com>

  [ Merge of http://go/wvgerrit/35300 ]

  Use the switches proposed in b/38033653 (as much as possible - some
  conflicts with protobufs and gtest prevent fully accepting them).

  Switch to clang for x32 build; ensure that both x86-64 and x86-32 builds
  compile and link cleanly.

  BUG: 38032429
  BUG: 38033653

  This partially resolves b/38458986

* Android build fixes

  Author: Rahul Frias <rfrias@google.com>

  [ Merge of http://go/wvgerrit/35102 ]

  These corrections address compile warnings and errors for android
  and unit tests.

* Embedded License: Add sub license key sessions.

  Author: Jeff Fore <jfore@google.com>

  [ Merge of http://go/wvgerrit/33680 ]

  NOTE: this adds the AddSubSession() method, but it is not yet being
  used. Use and proper cleanup is in an upcoming CL.

* Embedded license: Add track label field.

  Author: Jeff Fore <jfore@google.com>

  [ Merge of http://go/wvgerrit/33660 ]

  A new track label field (a string) is added to the key container and the
  sub session data objects.

  This field will be used in handling sub license requests.

* Embedded license: extract keys from init_data.

  Author: Jeff Fore <jfore@google.com>

  [ Merge of http://go/wvgerrit/33621 ]

* Embedded license: add protobuf messages.

  Author: Jeff Fore <jfore@google.com>

  [ Merge of http://go/wvgerrit/33620 ]

  also sync the widevine header definition with recent naming changes.

* Improve handling of provisioning response errors.

  Author: Gene Morgan <gmorgan@google.com>

  [ Merge of http://go/wvgerrit/33600 ]

  Separate out the case of no response and the case
  where the message is believed to be a JSON+base64
  message but it doesn't parse properly.

BUG: 71650075
Test: Not currently passing. Will be addressed in a subsequent
  commit in the chain.
