Add New Parameters to CreateUsageTableHeader

Browse Source 
Merge from Widevine repo of http://go/wvgerrit/23166

This changes OEMCrypto_CreateUsageTableHeader so that the new header
is passed back in a buffer to the cdm layer.

I hacked out the haystack call and just stubbed out the mock call.
This should still build and run with previous liblevel3.a builds.

I also removed from the header some function names that are no longer
part of OEMCrypto v13.
