Previously, we were assuming that each IC protocol version was tied to a specific host version. For example, some Windows 10 preview hosts only support v3 TimeSync even though driver assumes v4 is supported by all Windows 10 hosts. The guest will stop trying to negotiate even though older supported versions may still be offered by the host. Make IC version negotiation more robust by going through all versions that are supported by the guest.
