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.

Created a new test for stressing OEMCrypto's ability to generate
OTA Keybox provisioning requests. This forces the TA to retrieve
keys from KM, generate certificate and sign the request. This is
intended to find any unexpected system degradation within the
device's TA(s).

Certain integration tests were depending on the provisioning server
only sending short duration (~2 minute) certificates when testing
the CDM's ability to enforce expiration periods. This behavior of
the server was not reliable, resulting in device test failures from
server behavior changes.
The DRM certificate provisioning server allows the requester to
optionally provide a desired certificate duration in the request
URL. The tests which test the CDM's ability to enforce certificate
durations will now explicitly specify the certificate duration
required by the test.

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.

For an EVT device, without a keybox or with a test keybox, we want it
to fall back to L3. However, when running the unit or integration
tests it should continue running tests with test keybox. This will
allow us to test L1 oemcrypto on an EVT device, while still using an
EVT device for dogfooding video content at the L3 level.

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.

If the debug count for ignoring an L1 keybox is still non-zero after
successfully processing an OTA keybox request, the dynamic layer MUST
return a failure to the CDM to keep the CDM and dynamic layer in
agreement that the L1 keybox should continue be treated as invalid.
This will trigger a fallback; but the fallback can be canceled via
the debugging app.

It was assumed that L1 would be tried before first reverting to L3 when
performing OTA keybox provisioning. If an app automatically defaults
to L3, it may get into a provisioning loop if the device wants to
perform keybox provisioning.
Now, OpenSession() will check the security level before suggesting OTA
keybox provisioning back to the app.

discrepancy reduces the quality of devices' metrics and limits

The CDM needs to report a system ID to apps on devices where L1
OEMCrypto implementations that are currently waiting for a new
keybox. A placeholder system ID is now used. This ID cannot be
used for DRM certificate requests or license requests.
Device ID has a similar issue, but it might not effect all devices.
If getting the device ID fails due to a missing keybox, it will
return an empty device ID.

This changes adds a custom debug property for changing the fallback
policy used for the system. Depending on the value set, the device
will either use a "fast" fallback (30 seconds) or "default" fallback
(~1 day with exponential backoff). Setting this property to either
"fast" or "default" will end the current fallback if it has been
triggered.

If the MediaDrm property string debugIgnoreKeyboxCount is set to 1,
then the keybox will be ignored on the next initialization. This will
force an OTA keybox reprovisioning.
Equivalently, a 1 may be written to the file

In order to test a failed reprovisioning step, a value of 2 may be

The basic test was failing when using the testbed oemcrypto
because the testbed deletes its keybox on each

oemcrypto whenever all the crypto sessions are deleted. This
