Fred Gylys-Colwell 16d9abca4c Update copyright notice and fix entitlement key sizes
This change updates the copyright notice to make it more clear that
the code is distribued under the Widevine Master License Agreement.

It also updates the unit tests and sample code to correct the useage
of AES 256.  AES 256 is used to decrypt entitled content keys, but it
is not used to decrypt key control blocks.
