Adds a new `cas` directory to the ports/linux project. This contains
an end-to-end demo of OEMCrypto CAS functionality, using the Linux
tee_simulator as a base.
Test: from ports/linux/cas dir: `CDM_DIR=~/work/cdm-dupe ./scripts/build.sh && CDM_DIR=~/work/cdm-dupe ./scripts/run.sh`

We want to transition to using GTEST_SKIP to skip unit tests instead of
modifying the GTEST_FILTER variable. This does so for tests that require
RSA 3072 support.

Changes the OPK session state machine to allow API_MOVEENTRY in
the same circumstances as API_CREATENEWUSAGEENTRY. Adds a test
to trigger the same situation as the linked bug.
The test cases in the bug fail because OEMCrypto_MoveEntry() is
called immediately after OEMCrypto_CreateNewUsageEntry(), but the
session state machine has different filters for the two calls.
Furthermore, OEMCrypto_CreateNewUsageEntry() doesn't change the
state machine, so we should align the two filters to allow
OEMCrypto_MoveEntry() to be called immediately after
OEMCrypto_CreateNewUsageEntry() in all situations where
OEMCrypto_CreateNewUsageEntry() is allowed.
The existing OEMCrypto defrag tests did not catch this edge case
because the test helper functions always do something to modify the
state machine after calling OEMCrypto_CreateNewUsageEntry().

Expected flow, which begins with a device that has already been
provisioned with Prov 4 stage 1:
1. OEMCrypto_InstallOEMPrivateKey()
2. OEMCrypto_GenerateCertificateKeyPair() -> wrapped_csr_priv
3. OEMCrypto_LoadDRMPrivateKey(wrapped_csr_priv)
4. OEMCrypto_PrepAndSignProvisioningRequest() to create a Prov 4
provisioning request message type with a CAST request in the
message body
5. Server sends a Prov 2 response. Server side derivation uses CSR keys
to derive session key, mac keys, and encryption keys.
6. OEMCrypto_DeriveKeysFromSessionKey(), same derivation as server side
7. OEMCrypto_LoadProvisioning(), use derived keys to verify + decrypt
The OEMCrypto_LoadDRMPrivateKey() step can happen before or after the
PrepAndSignProvisioningRequest() call.

OEMCrypto_ReassociateEntitledKeySession() should prevent an entitled key
session from being associated to an arbitrary entitlement session.
Validations added/updated in this CL:
1. at least one entitled key is supposed to have matching entitlement
key in the new session;
2. the key control block in the new entitlement key should remain
unchanged compared to the existing entitlement key.
Updated OPK and ref/testbed implementations.

If the BCC has an RSA key, then it needs to be parsed by
BoringSSL, which expects rsaEncryption as the encoding type.

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.
