The version number for N-MR1 has been increased to 7.1.1, which
triggered our version number canary. Since this is still N-MR1, no
Widevine version number update is necessary as we already updated it for
N-MR1, but the canary needs to be updated.

This CL pulls the cache flush code out of the haystack code and into
the adapter level. This is so it will be built with processor
specific compiler flags instead of as part of the precompiled binary.

For CTR encryption mode, when a subsample ends with partial block that
is continued on the next subsample, both blocks should have the same
IV. This allows an implementation of OEMCrypto to optimize their
decryption algorithm.

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 updates the version number to v4.1.0 for the NYC-MR1 release. It
also updates the canary to pass on the nyc-mr1-dev branch.

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.

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.

This CL changes the android/build_and_run_all_unit_tests.sh script to
push exectuables to /data if it can't push to /system/bin.
The script run_all_unit_tests.sh will check if test files are in /data
and run those first, if not, it runs the files in /system/bin.
This change is needed to test unit tests on devices where /system/bin
is a read only file system, even after running "adb remount".
This CL will help verify, but will not fix

Because Widevine core always has a decrypt mode set, even on unencrypted
calls where we potentially do not know the crypto mode, it will reject
unencrypted decrypt calls for sessions that have been flagged as
AES-CBC, since the crypto mode defaults to AES-CTR.
The fix is to not validate the crypto mode on unencrypted decrypt calls,
as the data won't be getting decrypted anyway.
