Original change's description:
> New NTLMv2 Implementation.
> 
> - Supports NTLMv2 with Extended Protection for Authentication (EPA)
>   and Message Integrity Check (MIC).
> - Adds required methods to buffer reader/writers to support NTLMv2
> - Adds optional version/mic fields to all messages
> - Removes protocol level tests from HttpAuthHandlerNtlmPortableTest.
>   A previous CL already implemented all those tests directly against
>   NtlmClient. The tests at that level only existed to validate that
>   the behavior of the old and new implementation were the same.
> - Future CL updates fuzzer to support v2.
> - This CL does not activate NTLMv2. The code still defaults to NTLMv1.
