Extended the CDM layer to report OEMCrypto's production readiness
via string property query.
If OEMCrypto implementents OEMCrypto_ProductionReady(), then the
reported readiness by the CDM will report "True" or "False".
If OEMCrypto does not implement OEMCrypto_ProductionReady() then no
level of readiness is assumed, and the CDM will report "Unknown".

- replace StrictMock<MockCD<> with NiceMock; otherwise,
"uninteresting mock for isOpenSession" will return fail by default

Parameterizing GtsMediaDrm tests exposed a few issues. If secure stops
were stored at L3 security level, retrieval would fail. This CL
checks L3 if the secure stop was not found at the default security
level.

Within the CDM and OEMCrypto tests, there were a few OEMCrypto function
calls where the final size of the output buffers were not being
resized. For several of these functions, an initial call is made with
zero-length output buffers, expecting OEMCrypto to return
ERROR_SHORT_BUFFER; followed by a call with buffers at least as large
as specified by OEMCrypto. However, for some operations, OEMCrypto
makes an estimate on the final size on the first call, specifying the
exact size only after performing the operations.
This is the case for the wrapped key returned by
OEMCrypto_LoadProvisioning(). The provisioning response contains a
padded + encrypted DRM key. OEMCrypto does not know the actual size
of the key until decrypted, and the actual DRM key might be smaller.
There was a OEMCrypto test for OEMCrypto_BuildInformation() which
was enforcing the wrong behaviour. This has been updated.

The Widevine CDMs have never validated the padding on AES keys. However,
the code to ignore the padding was unusual and based on the assumption
the keys would always have either 0 or 16 bytes of padding and did not
handle other cases correctly. This patch updates the padding-ignoring
code to just do the obvious thing: Reject keys that are too small and
ignore all extra bytes regardless of count.

This changes extends the CryptoSession logging to include the OEMCrypto
session ID in its decrypt failure logs, and adds a new CdmSession
decrypt failure log which includes the CDM session ID. The CDM session
directly maps to the MediaDRM session ID, making app debugging easier.
The Decrypt() code pathway is one of the most frequently called
portions of the CDM code, and the pathway attempts to make as few
logging calls as possible in order to keep latency low and log
verbosity to a minimum. It is anticiapted that when a call to
Decrypt() fails, there will be a burst of failures as the app may
make several calls to Decrypt() before handling the first decrypt
error.
To keep logging low, the following rules are followed:
- CryptoSession: decrypt errors are only logged when the decrypt error
changes.
- CdmSession: decrypt errors are only logged when the last call to
decrypt had succeeded.

This patch changes the code path in the CDM so that the first-stage
provisioning request for Provisioning 4.0 is always encrypted with the
Widevine service certificate instead of the client-set service
certificate, reflecting that the first-stage provisioning is always
handled by Widevine.
This patch also makes several methods on the ServiceCertificate class
const. This has no impact on their behavior.

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.

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.

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).
