This change includes additional fields in DeviceCertificate, License and
UsageInfo.
New DRM certificate will include a creation and expiration time.
In addition acquisition_time_seconds will allow the client to calulate
expiration time even when client and provisioning service clocks
are not in sync.
expiration_time_seconds will allow clients to expire DRM certificates
that do include an expiration time. A random value within a window
(4-8 months after update) will be calculated to avoid
a provisioning storm.
Drm certificate will be added to offline licenses. In a future release,
licenses will be removed on expiry and the certification information
that needs to be sent to the license service will be reduced.
This should reduce space overhead.
UsageInfo will use a certificate cache in case multiple usage info
entries use the same DRM certificate.

The coverage framework used by Android requires the process to call
exit() for coverage information to be dumped after the tests.
Android unit tests have been adapted to use the a new main module.
The core test_main.cpp used by integration tests has been updated to
call exit().

This patch adds an annotation to the one place in the codebase where we
intentionally fall through between switch statement cases, in order to
appease stricter compilers.

This closes a crypto session when the provisioning request fails. We
cannot be as eager when handling the response as the app may have
multiple simultaneous provisioning attempts in flight. In this case
all provisioning responses except the one associated with the last
request will fail. If we close the session on error, even the one
associated with the last request may fail.

Sync with the latest version of drm_certificate.proto to add in
certificate expiry time. Add in signed_drm_certificate.proto and remove
messages from device_certificate.proto.
SignedDrmDeviceCertificate and DrmDeviceCertificate are now named
SignedDrmCertificate and DrmCertificate. This necessitated non-proto
changes.

The shared memory buffer used by srcPtr can be freed by another
thread because it is not protected by a mutex. Subsequently,
a use after free AIGABRT can occur in a race condition.
SafetyNet logging is not added to avoid log spamming. The
mutex lock is called to setup for decryption, which is
called frequently.
The crash was reproduced on the device before the fix.
Verified the test passes after the fix.

The sc-dev branch on Android is out of sync with several important
changes on the CDM master branch. This changes copies several CLs.

OEMCrypto unittest: generic crypto APIs
Add unit tests to verify that generic crypto APIs do not crash for large
input buffer lengths and signature lengths.

Fix secure buffer tests in OEMCrypto testbed
The secure buffers were not being used correctly in the testbed, and
were failing OEMCryptoMemoryCopyBufferForHugeBufferLengths.

Reject block_offsets of 16 or greater in OEC Ref
This is a potential security hole. We will be enforcing that OEMCrypto
rejects this in an upcoming test, so the Ref must be updated to reject
it.

Check for buffer overflow when computing subsample size
The test DecryptCENCForNumBytesClearPlusEncryptedOverflowsSize
cleverly picks num_bytes_clear + num_bytes_encrypted = 1 after integer
overflow. This is in the refernce code, level 3, and odkitee.

Add size check for IV in OEMCrypto APIs
IV is supposed to be 16 bytes but the size is never checked before iv
