Add Single Sign On support to HTTP Authentication handlers.

Currently this is implemented on Windows for the NTLM and Negotiate schemes.

This CL does not introduce the hooks to actually use Single Sign On in response to a 401/407 request - that will come in a later CL.

This behavior is disabled for now as well.

BUG=29862
TEST=Ran unittests, and Chrome against a server with authentication challenges.
