r21250: Partial fix for BUG 4093: Make %a expand to "Vista"

based on the flags2 values in the negprot request.

This also includes some code for testing the dialect
strings for "SMB 2.001" but this is unreliable as Vista
only sends that in the 1st negprot and caches the fact
that we don't support it.  Restartnig the WOrkstation
service on the client clears the cache.
