This change moves some code - that was nearly identical between the
clear subsample and encrypted subsample paths - into a common helper
method.

The IV incrementation code in Widevine DRM Plugin includes complexity
for handling partial crypto blocks in "cens" mode, a situation that
cannot actually happen. This commit changes the code to no longer handle
this case specially.

This patch removes the logic that calculates the "pattern offset" from
the Android glue layer. There is no such thing as a pattern offset, and
setting this value to anything other than zero may break cens mode on
some devices.
To reduce the risk of setting this value to anything other than zero,
the offset_blocks parameter has been removed from the pattern descriptor
in the CDM Core. It will have to remain part of OEMCrypto v11,
unfortunately, but the code to set it to zero is now centralized in
CryptoSession.

This is to correct for when HDCP validation failure at the OEMCrypto level

Some decryption errors were being reported as
vendor-unique diagnostic codes that were not generally
actionable by an app. Recently a new
MediaCodec.CryptoException code was added so these types
of failures can be reported as ERROR_UNSUPPORTED_OPERATION,
in which case the app can use an alternate DRM
configuration in a way that does not require
vendor-specific handling. This change remaps this class
of decrypt errors to the new error code.

This commit adds support for CBC and Pattern Mode to the MediaCrypto
implementation. These are the only changes needed to support HLS. (No
change is needed for MediaDrm, as it already passes HLS initialization
data along to the core without closely inspecting it, as it should.)
Following this change, the glue layer also supports the CENC, CBC1,
CENS, and CBCS modes from the forthcoming update to the ISO-CENC spec.
Note that, in order to differentiate CBC1 and CBCS, we have to cue on
the presence or absence of a pattern, which may not continue to be
sufficient in the future if a third CBC mode using patterns is ever
added.
Note that the unit tests for this code remain disabled for now. New
unit tests are forthcoming in a separate commit.

As an optimization, the Media Server now unloads our library when not
in use. This has exposed a bug by which we were never deleting the CDM
singleton. Fix is to make WvContentDecryptionModule an Android smart
pointer ref base and then make sure all the plugins store a strong
pointer to it. The singleton is a weak pointer, so when the last
plugin is cleaned up, the CDM will be as well. And on the off chance
that the library isn't immediately unloaded, the singleton code will
generate a new CDM next time one is needed.

Implements the optional setMediaDrmSession() method. To enble this,
support was added to the core to report if a session ID is valid.
As a consequence of this, in the tests for the CryptoPlugin,
construction of the plugin must be deferred until all gMock
expectations are set, as construction now calls into the CDM core.
This is a merge of two changes from the Widevine CDM repo:

Bug: 16034599
Change-Id: Id2ea5635bf732eabf1fd33712ff8bab6cf1a1745
During session sharing, when a sample contains both clear and encrypted
subsamples, subsample flags would on occasion be set incorrectly. Clear
subsamples would be sent to the current session, while encrypted ones
would incur a key id to session lookup and be sent to the appropriate session.
The sessions would then receive decrypt calls with subsample flags
incorrectly set.
In order for this to work correctly all subsamples within a sample need to be
sent to the same session. This requires that key ids be specified and
checked if at least one of the subsamples is encrypted. If however none of
the subsamples are encrypted then a valid key id may not have been provided
to MediaCrypto, and the subsamples may be sent to any session.
In order to support this, the CDM decrypt will now allow the caller to
specify whether to validate the key Id.
Then a check is added to wvcrypto determine whether to ask the CDM to
validate the key ID based on the clear/encrypted states of the subsamples.
The list of subsamples is already being preprocessed, so this
additional check just determines if any subsamples are encrypted, and sets
the validation flag appropriately.

Changes the behavior of requiresSecureDecoderComponent() to query the
session for whether a lowered security level has been requested
before querying the system to see what its default security level is.
As part of this, we added a new QuerySessionStatus() method to the
CDM that gets status info on a session-specific level, such as the
effective security level of a session.

WVCryptoPlugin was not properly implementing part of its responsibilities to
AES-CTR in ISO-CENC. Specifically, it was not incrementing the IV after each
block.
Also, I have greatly expanded the unit tests for decrypt() to catch more edge
cases.
This change fixes the two failing test vectors in the Java integration tests.

Removes the status query from WVCryptoPlugin's decrypt method. It was not
providing any additional security since it was not cryptographically secure,
and querying status is an expensive operation on some devices. It should not
be done on a frequent basis, such as in every decrypt call.
