OEMCrypto v11 Documentation and Headers

Browse Source 
Merge from widevine repo of http://go/wvgerrit/16186

These are the OEMCrypto v11 documents and header files. I have updated
just enough code so that existing unit tests pass.  New unit tests,
the reference implementation, and the level 3 implementation are in
future CLs.
