0419b55222 Merges to android Pi release (part: 1)
Below are a set of CLs being merged from the wv cdm repo to the android repo.

* Fix handling of OEM Cert public key.

  Author: Srujan Gaddam <srujzs@google.com>

  [ Merge of http://go/wvgerrit/27921 ]

  This is a potential fix for b/36656190. Set aside public
  key on first call to get the public key, and use it afterwards.
  This gets rid of extra calls to OEMCrypto_GetOEMPublicCertificate(),
  which has side-effect of staging the OEM private key.

  This also fixes a problem where the public cert string was
  not being trimmed to match the size returned by
  OEMCrypto_GetOEMPublicCertificate().

* Complete provisioning request/response for Provisioning 3.0

  Author: Gene Morgan <gmorgan@google.com>

  [ Merge of http://go/wvgerrit/27780 ]

  Fix bug on provisioning request path where GenerateDerivedKeys()
  was being called when preparing to generate the signature.

  Add message signature verification, and call correct OEMCrypto
  routine to rewrap the private key (OEMCrypto_RewrapDeviceRSAKey30).

* Implement Cdm::deleteAllUsageRecords()

  Author: Gene Morgan <gmorgan@google.com>

  [ Merge of http://go/wvgerrit/27780 ]

  Delete all usage records for current origin.  Removes usage
  records from file system and retains the PSTs.  The deletes
  any usage entries matching those PSTs held by OEMCrypto.

  BUG: 35319024

* Remove stringencoders library from third_party.

  Author: Jacob Trimble <modmaker@google.com>

  [ Merge of http://go/wvgerrit/27585 ]

  We have a fork of the stringencoders library that we use for base64
  encoding.  This reimplements base64 encoding to remove the extra
  dependency and to reduce the amount of code.

* Add Cdm::deleteUsageRecord() based on key_set_id.

  Author: Gene Morgan <gmorgan@google.com>

  [ Merge of http://go/wvgerrit/27605 ]

  Delete specified usage record from file system usage info and
  from OEMCrypto.

  BUG: 35319024

* Modifiable OEMCrypto

  Author: Fred Gylys-Colwell <fredgc@google.com>

  [ Merge of http://go/wvgerrit/24729 ]

  This CL adds a new variant of the OEMCrypto mock code that adjusts its
  behavior based on a configuration file.  This is intended for
  testing.

  For example, a tester can set current_hdcp to 2 in the options.txt
  file, push it to the device, and verify that a license is granted for
  HDCP 2.0.  Then the tester can edit the value of current_hdcp to 1 and
  push the file to the device.  Playback should stop because the license
  is no longer valid.

  This variant uses a real level 1 liboemcrypto.so to push data to a
  secure buffer.  That means we can test playback for a license that
  requires secure buffers on an Android device with real secure buffers.

  BUG: 35141278
  BUG: 37353534

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

cdf309b9f4 Reject session clobbering and namespace fixes
* Reject session clobbering.

  [ Merge of http://go/wvgerrit/14634 ]

  This fixes a bug in I17de92b3e682c9c731f755e69466bdae7f560393 in which
  sessions can be clobbered by a forced session ID.  This bug manifested
  in subtle test failures which involved repeatedly creating sessions.
  This was traced to OEMCrypto not being terminated, then upward to a
  leaked CryptoSession and CdmSession, and then finally to clobbered
  session IDs.

  To avoid the bug in future, first, reject duplicate session IDs.
  Second, change the OpenSession API to make forced IDs explicit.

* Fix unit test namespaces.

  [ Merge of http://go/wvgerrit/14622 ]

  This fixes some odd errors that occur when linking multiple test
  suites into one executable.  When two object files both contain
  a definition of wvcdm::MockCryptoSession, for example, one will win
  silently and cause the other's tests to misbehave and/or crash.

  The solution is to put all mocks into an anonymous namespace, since
  each wvcdm::(anonymous)::MockCryptoSession is separate.

  In order to avoid lots of repetitions of wvcdm:: in the anonymous
  namespaces, all anonymous namespaces in unit tests now live inside
  or the wvcdm namespace.  This has been done even for tests which
  are not currently using mocks.

* Move timer and timer_unittest to Android.

  [ Merge of http://go/wvgerrit/14619 ]

  These are not used anywhere else.

7b262e1d02 Alphabetize & Googleize Header Inclusions
(This is a merge of http://go/wvgerrit/13761 from the Widevine
repository.)

This cleans up our includes to be in Google Style Guide order and in
alphabetic order, for the parts of the code that are expected to
follow Google Style.

This also converts places in our code that were including C headers
in the C++ style (i.e. <cstring> instead of <string.h>) to use C style
instead. This is because, although it was not causing problems for us
yet, on Android these actually include different headers. (<cstring>
is provided by libcxx, while <string.h> is provided by Bionic)

Lastly, this change puts all headers that do not come from within our
project in <brackets> instead of "quotes," which was not being done
consistently.

This change is explicitly NOT trying to standardize the spacing of our
header includes. I have tried to respect, in each file, the spacing
style already present.

0a564039ca Cleanup namespace ending comment
(This is a merge of http://go/wvgerrit/13400 from the Widevine CDM
repository.)

Replace "};  // namespace" with "}  // namespace":
ag -l --ignore-dir third_party "};  //" | \
while read f; do sed -r -i 's/\};  \/\//}  \/\//' $f ; done

Replace "// unnamed namespace" with "// namespace":
ag -l --ignore-dir third_party "unnamed namespace" | \
while read f; do sed -r -i 's/unnamed namespace/namespace/' $f ; done

a3b0d83d19 Run clang-format on Core
This copies over formatting changes from the Widevine CDM repository
that resulted from running clang-format with Google style on the
shared core/ directory. It also copies over some rewordings of log
messages that were made at the same time.

Aside from the changed log messages, this should not affect behavior
or functionality.

b0694bef17 Correct test vector in base64 test
This is a copy of
https://widevine-internal-review.googlesource.com/#/c/10050

The non-encoded base64 test vectors were modifed for the source
release, but the encoded test vectors were not updated to match.  This
CL updates the encoded test vectors to match.

1cd8195d88 OEMCrypto Usage Tables
This CL adds usage tables to the OEMCrypto reference implementation
(mock) and unit tests.

There is also a new parameter called oem_crypto_require_usage_tables
that determines if the usage tables are required or not.  This is set
to true for Android and false for all other platforms.

This CL is most of OEMCrypto version 9 updates.
