OEMCrypto v13 Header and Stubs

Browse Source 
Merge from Widevine repo of http://go/wvgerrit/22899

This is most of the header changes for OEMCrypto v13.  This updates
just enough of the code that existing unit tests build and pass.

The documentation will be reviewed in http://go/wvgerrit/22887.  When
that CL has been approved, comments in the code will be updated to
match.

Real code will be broken into several other CLs.
