When an offline license is reloaded, if it does not have a usage entry
to indicate when the rental clock was started, the start time defaults
to 0 in the ODK library (in OEMCrypto). This CL changes the code to
start the rental clock in this case. It does this by signing a dummy
message, which triggers the ODK library to start the rental clock.

When OEMCrypto is v16, but the license server is v15, we should not
create a new nonce for a license renewal. However, the request does
need a nonce or the license server will not generate a valid key
control block. So we should use the nonce that came from the original
license.

Add options to dump Widevine Cdm properties,
Widevine Cdm metrics, or both.
The valid arguments are Cdm Metrics (m|M) or Cdm Properties (p|P).
If no arguments are provided, both Cdm properties and
Cdm metrics will be displayed.

After changes made to how the usage table is defragged by the CDM,
it was determined that there is no use in selecting more than a single
entry from the usage table to evict. The only failure that can occur
when evicting an entry is if the last entry is in use, in that case,
evicting other entries will still result in a failure.
This change cleans up the LRU algorithm and test cases to reflect
the new functionality.

Several tests that make parallel license requests were disabled due
to a flaky server failure unrelated to CDM code. Most of these tests
are now re-enabled to ensure the multi-threaded license requests is
functional on V16.
These tests remains disabled for L3 due to continued flakiness.
Added a lock around the initialization of the SSL library to prevent
issues with license requests getting garbled.

No one was claiming ownership of the metrics object in
CertificateProvisioningTest, resulting in a leak. This patch makes the
test hold onto ownership.

The device file unit tests use some custom matchers that were written
back when we didn't have C++11. Because gMock requires std::tuple to
pass a pointer AND a length to a matcher, these matchers had to estimate
the length of the file. This technically meant they were causing a
benign buffer overrun sometimes.
Since we have C++11 now, we can fix this by using a matcher over a
std::pair of the pointer and length. I also took the opportunity to
refactor the matchers a little. The old matchers had many very specific
overloads and also collided with the names of some standard gMock
matchers. Now there are just two more-general matchers with unique
names.

The CDM was using unique CDM error codes for the various cases
where OEMCrypto would return INSUFFICIENT_RESOURCE. However, these
error codes were being incorrectly mapped at the Android level,
resulting in incorrect errors in the MediaDRM layer.
At no point does the CDM handle different INSUFFICIENT_RESOURCE_x
within the same case, as such the use of unique codes are limited.
This CL removes the unique codes, and unifies them under the same
CDM error code.
This CL also extends SelectKey to handle error codes returned by
LoadEntitledContentKeys.

CDM sessions should not be able to load multiple usage entries.
OEMCrypto already prevents multiple entries from being loaded by the
same OEMCrypto session; however, restoring a key typically creates a
new OEMCrypto session, which should not be allowed twice within the
same CDM session.
This test verifies that CDM returns an error if restore key is called
multiple times within the same session.

The WVDrmPlugin has a single CdmIdentifier. The CdmIdentifier contains
a SPOID that is calculated from the device ID (keybox or OEM cert),
an application reverse domain name and possibly an origin.
The CdmIdentifier is set and SPOID calculated on certain calls into
WVDrmPlugin. Once it is set, it will not be recalculated. We prevent
certain operations such as modifying the origin once the CdmIdentifier
has been set as this will require recalculating the SPOID.
Recalculating the SPOID may affect open sessions or calls in progress.
In a similar way, modifying the security level, will affect the
Device ID value and in turn the SPOID. The security level cannot be modified
if any sessions are open. This does leave open the possibility that the
SPOID may be calculated at one security level, sessions are then closed,
and the security level is then changed without an error being flagged.
The provisioning certificate file name is based on the SPOID. When
the SPOID does not match the security level, either the provisioning
information may not be found even though that security level has
been provisionined or the provisioning information may be stored
in an incorrect location if provisioning occurs.
The correct solution is to prevent modifications to the security level
once the CdmIdentifier is set. This is a behavior change and might
impact apps. We will reevaluate this for the next release.
For now, we will work around this. When the CdmIdentifier is set for L3,
we will calculate SPOIDs with both L1 and L3 device IDs and check if
provisioning previously occurred with SPOIDs calculated for that level.
If so, use that level, otherwise use L3.
