Merges to android Pi release (part 3)

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

* Add CDM status return for decrypt blocked by HDCP.

  Author: Gene Morgan <gmorgan@google.com>

  [ Merge of http://go/wvgerrit/28062 ]

  New status code is kKeyUsageBlockedByPolicy. It is returned by the decrypt()
  call instead of kDecryptError or kNoKey.

  Also shuffled the CDM status returns to define the EME-aligned codes
  first, and added comments to highlight the differences in handling.

  BUG: 37540672

* Change division and mod ops to relocatables

  Author: Srujan Gaddam <srujzs@google.com>

  [ Merge of http://go/wvgerrit/28600 ]

  This is similar to I2dad1028acf295288cd10817a2bcff2513c053c9.
  We should be using the relocatable functions instead of the
  native division and mod operations.

* Cleanup Encrypted ClientID in provisioning request

  Author: Gene Morgan <gmorgan@google.com>

  [ Merge of http://go/wvgerrit/28083 ]

  b/36897239

  Staging server does not support it (or the client is not constructing
  it properly).  Leave it disabled pending investigation.

* Certificate Provisioning fixes.

  Author: Gene Morgan <gmorgan@google.com>

  [ Merge of http://go/wvgerrit/28066 ]

  Partial fix for BUG: 37482676
  Partial fix for BUG: 37481392

  Update service certificates, get rid of DEV/QA root certificate.
  Provisioning request and response are base64 (web-safe) encoded.
  Response is optionally JSON-wrapped.

  Change ConfigTestEnv; clearer comments and a closer match to reality.

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