Clang and GCC allow for warnings against the arguments for printf-like
functions (e.i. LOGx). These validate that the format type specified
in the format string match the corresponding argument type.
Most of the time, format specifer errors are benign; hence why they
haven't been seen as an error so far. However, with the enabling of
specifier warnings and the enabling of warnings as errors on certain
platforms, these existing errors need to be addressed.
This CL enables format specifier warnings for most of the Widevine
code, with the OEMCrypto L3 implementation which has a single error
which requires a fix in the haystack code before being fixed in the
Widevine branch.
Strict format string warnings are not enabled for non-LP64 systems.

In v16, OEMCrypto specifications required that an error be returned if
multiple attempts are made to load an offline license into a session.
This caused the GTS test testConcurrentDrmCertificates to fail. It was
introduced to verify that a license could retrieved and loaded into a
session and then restored. This was based on an app use case.
Ideally we would like to disallow a this behavior but need to make sure
it is not being used by apps.
For now this will be allowed. If detected, the CDM will reintialize the
OEMCrypto session and allow the license to be restored.

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.

ATSC 3.0 allows for licenses to be downloaded OTA and are tied to
a DRM certificate that may be shared across apps. The provisioning
process for ATSC may happen at the factory or during an OS update.
This contrasts from the regular OTT model, which requires that
provisioning and license download have an uplink as well as a
downlink connection.
This adds support for the ATSC mode property. ATSC mode can only be
set (or unset) before sessions are opened. Once the CDM identifier is
set/sealed, requests to modify the ATSC mode will be rejected.
If one needs to open sessions with both ATSC mode and regular (non-ATSC)
mode, separate MediaDrm objects will need to be created. The default
mode is to not use ATSC.
Enable ATSC mode by calling
mediaDrm.setPropertyString("atscMode", "enable")
Disable ATSC mode by calling
mediaDrm.setPropertyString("atscMode", "disable")
Provisioning and unprovisioning requests for ATSC will be rejected as
certificates will be retrieved by the ATSC service.

Several integration tests in WvCdmRequestLicenseRollbackTest had been
testing the duration of a license. However, the license they request
sets the playback duration and not the rental duration. That means the
timer we are checking does not start until the first playback. To fix
the tests, we simply add a decrypt operation right after the license
is received.

When processing a license release, the license is not loaded, so
OEMCrypto does not know nonce version information for the core
message. It assumes that all license releases are v15, so it is not an
error for a license release to not have a core message.
This CL also adds some extra logging to tests so that we can track
content id and the pssh. This CL also updates some of the test content
policies when running the local license server. The local license
server is only used for debugging problems.

There are situations where an offline license file will remain on the
system after it's usage entry has been deleted. This would result in
its key set ID being reported as present by the CDM, but any
operations acting upon it will result in an error.
The app should be able to remove the license without error, so long
as the license file exists and no other OEMCrypto operations fail.
This change introduces a new error code LICENSE_USAGE_ENTRY_MISSING,
which indicates that a license's usage entry cannot be found.
A new integration test checks that the CDM can handle the calls to
removeOfflineLicense().

In earlier releases, provisioning would occur based on a cached
security level. If an open session call returned a NotProvisionedException
the security level would be cached for use with any future provisioning
call.
An app would have to set the security level, then call openSession,
have it fail and then request provisioning. This fits the normal flow of
most apps. Still on occasion, an app might change requested security level
after an openSession call failed. Using the cached security level
would result in unexpected behavior.
This change allows provisioning to occur at the last security level that
was set.

SPOIDs (Stable Per-Origin IDentifiers) were not correctly being
set during CdmEngine construction. This resulted in SPOID values not
being sent in provisioning requests. This caused the serial number in
the drm certificate to not be stable after a reprovision.
This behaviour appears to be true going back to O.
CdmEngine no longer takes a SPOID in the constructor since not all
callers use SPOIDs. A setter has been added in its place. Previously
spoid had a default argument to the constructor.
