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.

Protections schemes are specified using a 4CC code {"cbc1", "cbcs",
"cenc", "cens"}. A host to network conversion was performed when the
PSSH was created and inserted into the license request. A reverse
conversion was performed when the code was extracted from the
license response.
These conversions are problematic if the PSSH is created externally and
passed into mediaDrm. To address this, the conversions have been removed
and allow protobuf to handle byte ordering. For backward compatibility
we allow codes in either ordering.

SSL v3 is being disabled across Google infrastructure. Networking
code in integration tests used SSL v3 during HTTPS protocol negotiation.
Once this is disabled, it will cause integration test failures at
staging and UAT license servers.
With this change the client will use TLS 1.2. Insecure cipher suites
(TLS_RSA_WITH_RC4_128_MD5, TLS_RSA_WITH_RC4_128_SHA,
TLS_ECDHE_ECDSA_WITH_RC4_128_SHA, TLS_ECDHE_RSA_WITH_RC4_128_SHA)
have been disabled as well.

This will allow the license server to base licensing decisions on the

The final spec for CENC says that partial encrypted blocks are only
allowed for "cenc" mode, and not for "cens" mode. Also, the
pattern_offset must be 0 for all calls to OEMCrypto_DecryptCENC.
Review doc changes http://go/wvdelta11 and http://go/oemcrypto
Notice that this CL affects documentation and test code only. No
production code is affected.
