5da8da58f6 Corrections for big usage table support in L3
[ Merge of http://go/wvgerrit/26421 ]

* Corrects usage_table_header lifetime management. Earlier the
  UsageTableHeader class was a singleton tied to the CdmEngine lifetime.
  With SPOIDs there might be multiple concurrent CdmEngine objects.
  The UsageTableHeader class is now associated with OEMCrypto
  lifetime. There are two UsageTableHeader objects one for each L1 and L3.
  These get allocated/deallocated on OEMCrypto Initialization/Termination
  respectively.
* UsageTableHeader requires OEMCrypto, file read/writes and
  metric gathering to perform its required functionality. Because of the
  lifetime changes, CryptoSession, DeviceFiles and MetricsGroup objects
  need to passed to the methods rather than at Creation time.
* Miscellaneous fixes, when moving or deleteing entries.
* Adds usage_table_header_unittests.
* Addresses failures with request_license_test with secure stop in L3.

14c3a3865a Give Nonce Error Explicit Name
Merge from widevine repo of http://go/wvgerrit/24421

A nonce generation error for a certificate provisioning request had a
generic name Error2.  However, this is an actionable error by the
application: the application should wait 1 second and try again.
Therefore it deserves a more descriptive name.

0db3a137e9 Introduce UsageTableHeader class
[ Merge of http://go/wvgerrit/23820 ]

The UsageTableHeader class is a singleton that CDM sessions will share.
A separate object will be created for each security level. The class
synchronizes access to usage table header and associated data-structures
and controls when they are read in or written out to non-secure persistent
storage. Upgrades from a fixed size usage table (supported by previous
versions of the OEMCrypto API v9-12) are handled by this class.

84a14f2561 Generate key set ID on initialization and interface clean up
This is a merge of squashed CLs.

* Cdm Session and Engine interface clean up

[ Merge of http://go/wvgerrit/16387 ]

Key Set Ids have been removed from the CdmSession interface
(GenerateKeyRequest, Addkey) as they can be queried by an accessor.

The CdmEngine interface now allows one to specify or retrieve a session ID,
since both were not being used in a single call. Key set IDs are no longer
returned though GenerateKeyRequest as they was not being used.

* Generate key set ID when session is initialized

[ Merge of http://go/wvgerrit/16370 ]

Key set IDs are currently generated at different times in the
CdmSession lifecycle. Android generates key set IDs when the license
is received, while the CE CDM generates (or overrides them)
when the session is constructed.

The key set IDs are now generated when the session is initialized.
Key set generation cannot occur earlier as it has a dependency on
security level and in turn on crypto session initialization which
occurs when the session is initialized.

Depenencies on Session ID has caused other activities, construction of
PolicyEngine, CdmLicense, setting property CDM client sets to be
deferred from CdmSession constructor to Init().

Android will still retrieve the key set IDs after the offline license is
processed. For streaming requests, the key set will be
unreserved and discarded when the session is terminated.

85da7bdb98 Refactoring to cache service certs and initialization data
* Extend CdmLicense's stored_init_data_

  [ Merge of http://go/wvgerrit/14661 ]

  CdmLicense will store init data when a server cert must be
  provisioned.  After provisioning, the original init data can be used
  to generate the originally-intended license request.

  To do this before, the caller had to call CdmSession's
  GenerateKeyRequest with an empty InitializationData object.  However,
  the init data's type still had to be set, as did the license type.

  This CL allows the caller to use a truly empty InitializationData
  without a type.  To permit this, CdmLicense now stores a full
  InitializationData object, rather than just a copy of it's data field.

  With this CL, the caller also avoid storing the original license type.
  To accomplish this, CdmSession uses the already-set is_offline_ and
  is_release_ flags from the original call to reconstruct the intended
  license type.  The caller uses the new type kLicenseTypeDeferred.

  To facilitate storing whole InitializationData objects, they are now
  copyable.

  This ultimately simplifies server cert code for the new CE CDM.

* Store service certs in Properties

  [ Merge of http://go/wvgerrit/14664 ]

  This allows CE devices to mimic the Chrome CDM's behavior of sharing
  server certs between sessions.

  This also affects Android behavior.  Previously, provisioned service
  certificates were per-session, while explicitly-set service certs
  were per-DRM-plugin.  Now, both are per-DRM-plugin.

  A DRM plugin is associated with a mediaDrm object. Content
  providers will still be able to retrieve and use different
  certificates. The change here requires an app, that wishes to use
  different provisioned service certificates will have to use
  multiple mediaDrm objects. This is an unlikely scenario.

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.
