GetDeviceInformation() and GetDeviceSignedCsrPayload() are added to
cdm_engine and crypto_session, so that they can be queried by DRM
plugin. This is to allow the wv drm HAL to be able to extract BCC and
CSR payload to build CSR for prov 4 device registration, such that we
don't need a separate RKP HAL to do this job.
Changes to the DRM plugin to use the exposed methods will be in the
coming CL.

The `time_of_renewal_request` field in the clock_values struct was not being initialized. With this CL, we use a value of 0 to indicate a renewal has not been requested yet.
We also modify the check in `ODK_ParseRenewal` to use a value of 0 for the `time_of_renewal_request` to skip the check for a stale renewal. This is done because now that a "renew on license load" license starts the playback clock immediately, we need a different way to decide if a renewal from a previous session can be loaded.

It seems ODK_InitializeSessionValues is only used in initializing the session in OEMCrypto, so we can remove this check.

This includes testing overflow functions that are only used in the Widevine client repository.
This patch also includes the following fix for the previous commit:
Add type casting for ODK overflow function unit tests
Merged from http://go/wvgerrit/175893
The new ODK overflow unit tests are causing some unit test failures in oemcrypto-v18 due to mismatched type comparisons.

The previous code fixed a backwards compatibility error for v18 provisioning requests being parsed by a v17 or older server. This bumped the minor version number to v18.1. v17 servers are still expected to fail when trying to parse v18.0 provisioning requests, and v18.1 requests will pass.
However, it did not correctly account for existing v18.0 requests on v18.1+ servers. v18.0 messages were naively detected by a failure to parse, and the parse function was not run again. This left the resulting nonce and session_id values uninitialized.
This CL fixes that by explicitly handling the v18.0 and v18.1+ cases, ensuring that the parse function succeeds and all relevant information is copied over. Furthermore, the unit test that was meant to catch this edge case has been improved to validate the resulting parsed message.
All code changes affect the server. This does not affect the client code eg OEMCrypto

There are three changes here that should help reduce the
amount of duration test failures caused by clock skew.
First, we reported some skew when the test expected playback
to start immediately after loading the license. However,
with round-off, this could easily be more than 1 second. So
this does not warrent even a warning.
Second, the fake and real clocks were only synced after
computing how long to sleep. This is fixed by moving
SleepUntil to the TestSleep class and having it sync before
computing the delta and after doing the sleep.
Third, I am guessing that some failures due to unexpected
lenience were caused by the rental or playback clock being
started at the end of signing the license or the end of the
first decrypt instead of the beginning. We work around this
by recording how long these operations take, and then adding
this extra time at the end of the check for FailDecrypt.

After the ODK_MAX_NUM_KEYS change, the core response is a pointer to an
array instead of an array. This check should ensure the index of the key
array can always be accessed.
