workarounds of unicode setup during protocol negoiation,seems to be a bug in windows. revalidated against fairly current samba, WinXP, Win7 and cinap'scifsd server for plan9. bug in virtual filesystem which could cause the filesystem todisappear if you looked in the Shares virtual file tweeks to Auth code (mainly tidying) and trying to get auth to work tovista.  turns out you need to apply a hotfix (regedit)http://support.microsoft.com/kb/957441 and cifs is happy with vista. major overhall of DFS code.  works much better but still does notcross servers and doesn't give any helpful messages when it fails :-( case significance is enforced by cifs, though you still cannot createMakefile and makefile as seperate entities.  This is enabled bydefault but can be disabled by a command line option. also fixed a bug in UNICODE handling, I got away with this on windowsbut cinap's cifsd drew blood. execute requests are always denied on cifs files.  Perhaps this tooshould be a command line option, but having plan9 executables on awindows server is a rarity IMHO. in CIFStreeconnect() removed ths strupr() call - trees are not neccessarlyupper case, some servers are case significant on volume/share names.
