workarounds of unicode setup during protocol negoiation, seems to be a bug in windows. revalidated against fairly current samba, WinXP, Win7 and cinap's cifsd server for plan9. bug in virtual filesystem which could cause the filesystem to disappear if you looked in the Shares virtual file tweeks to Auth code (mainly tidying) and trying to get auth to work to vista. 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 not cross servers and doesn't give any helpful messages when it fails :-( case significance is enforced by cifs, though you still cannot create Makefile and makefile as seperate entities. This is enabled by default but can be disabled by a command line option. also fixed a bug in UNICODE handling, I got away with this on windows but cinap's cifsd drew blood. execute requests are always denied on cifs files. Perhaps this too should be a command line option, but having plan9 executables on a windows server is a rarity IMHO. in CIFStreeconnect() removed ths strupr() call - trees are not neccessarly upper case, some servers are case significant on volume/share names.
