DeviceFiles uses a static variable for tracking license IDs which
have been reserved by a CDM session before officially storing the
license on the device. This variable was not protected by a mutex,
and a rare race condition would arise, either crashing the service
or getting it stuck in a loop.
This CL adds a mutex for protecting the set of reserved IDs.

Devices without a keybox may not have access to a device ID if the OEM
uses the device ID from the keybox as its source of truth. For
devices which have lost their keybox, OEMCrypto_GetDeviceID() was
assumed to return ERROR_KEYBOX_INVALID if that was the case; however,
Qualcomm's implementation was returning ERROR_NO_DEVICEID. Given that
both error codes are appropriate, the CDM has been updated to accept
both as an indication that the device ID cannot be retrieved, and that
the null device ID should be returned.

Qualcomm's implementation of GenerateOTARequest requires an open
session before attempting to generate an OTA keybox request. When
checking for OTA keybox support, the dynamic layer was not opening
a session, getting a different error than expected. Coincidentally,
this would trick the dynamic layer to thinking it was supported, but
hides useful error information.

Extended the functionality of the CdmEngine to check if the device
requires OKP and to initialize OKP resources if required. The
functionality of OpenSession() and GetProvisioningRequest() have been
the most affected. If OKP is required, these methods will signal to
the app that provisioning is required and will return an OKP request.
Once a device is provisioned, the OKP data is cleared away and the
CdmEngine will resume normal operation. Engines created after a
device is provisioned will immediately enter normal operations.
The exception is for CdmEngines which failed to perform OKP for some
reason and are still running. Those apps will need to restart before
gaining access to L1 operations.
