Merge from Widevine repo of two CLs.
Merge from Widevine repo of http://go/wvgerrit/94743
A license release should not have a core message. This CL adjusts the
existing unit tests to verify this. There is also a new unit test called
SecureStop that explicitly tests sending a secure stop in a new
session without first loading the license.

To reduce the number of OEMCrypto calls on the decrypt path, the maximum
subsample size will now be cached after the first call to retrieve it.

In OEMCrypto v16, we dropped support for 'cens' and 'cbc1'. However, we
did not redefine the pattern (0,0) to be a valid pattern for 'cbcs', even
though it was no longer being used to signal 'cbc1'. Instead, we made
the CDM reject CTR with a pattern ('cens') and CBC with a (0,0) pattern
('cbc1') to mirror the behavior of OEMCrypto v16.
However, some apps have been using 'cbc1' mode to decrypt audio in
'cbcs' content. This is normally not possible but is possible for a
subset of content. Furthermore, it is easy to do by accident because of
the way most packagers package 'cbcs' audio and the special significance
Widevine has historically given the (0,0) pattern.
This patch updates the CDM to not reject CBC with a (0,0) pattern but
instead treat it as 'cbcs' content. To decrypt it correctly, the pattern
is treated specially inside the CDM core and converted to the
recommended equivalent pattern — (10,0) — before passing the content to
OEMCrypto.

[ Merge of http://go/wvgerrit/94483 ]
With OEMCrypto V16 comes a new potential error code from calls to
DecryptCENC(). WARNING_MIXED_OUTPUT_PROTECTION may be returned by
supporting devices if one of the output devices does not meet the
required HDCP level for the decryption key/license; however the output
is instead restricted (by OEMCrypto) to devices that are secure. This
warning is informative to the CDM; but no action can/should be taken
by the CDM.
In addition, if DecryptCENC() returns an error/warning, it is likely
that the same status code will be returned on subsequent calls to
decrypt within the same crypto session. To reduce the number of logs
the CDM produces within the same crypto session only changes in error
codes are logged.
