78a4902214 Move functionality to policy_timer.
[ Merge of http://go/wvgerrit/164277 ]

No functional changes are made in this CL. policy_timer_v16 and
policy_timer_v15 derive from policy_timer. We have removed
support for OEMCrypto v15. policy_timer_v15 has also been removed.

This allows us to move functionality from policy_timer_v16
to policy_timer class. This will ease subsequent renew on
license load functionality.

68587be8a0 More policy engine/timers refactoring
[ Merge of http://go/wvgerrit/93838 ]

Some more rework of policy engine/policy timers code to support
timer and clock value handling introduced by OEMCrypto v16.

Changes are
* renamed methods to include rental duration since policies for v16 use
  rental and playback duration for all licenses. Previously rental and
  playback durations enforced timing for persistent licenses and license
  duration was used for streaming licenses.
* Moved some common code to the base PolicyTimer class from
  PolicyTimerV15.
* Corrected data member naming (policy_timers -> policy_timers_)
* Updated comments

c2cee8406e Policy Engine refactoring
[ Merge of http://go/wvgerrit/93743 ]

Reworks policy engine in preparation for changes to support timer and
clock value handling by OEMCrypto core messages in OEMCrypto v16.

No major functional changes have yet been introduced. Time and duration
evaluation has been devolved to a new policy timer class. Policy
specific to licenses that do not support OEMCrypto core messages
is handled by a Policy Timer V15 class. This ensures backward compatibility.

Backward compatibility may be needed if
 * OEMCrypto has not been upgraded to v16
 * Licenses were persisted before the device was upgraded to v16
 * License service does not yet support core messages

Some minor changes to when the current time was retrieved required
minor modification to test expectations.
