[Bug 425] Network UNC path handling

A user asked about this today
http://www.winehq.org/pipermail/wine-users/2008-April/032049.html
and pointed out that UNC paths are officially supported (see "Network Shares"
in
http://www.winehq.org/site/docs/wineusr-guide/misc-things-to-configure ),
so I looked at it a tiny bit.

Sure enough, if you smbmount something onto
dosdevices/unc/servername/sharename,

$ sudo apt-get install smbfs
$ sudo vi /etc/hosts (and add entry for name of windows machine 'fast')
$ smbmount -L fast (and verify the expected share is visible)
$ sudo mount -t smbfs //fast/dank /mnt
$ cd $HOME/.wine/dosdevices/
$ mkdir -p unc/fast
$ ln -s /mnt unc/fast/dank

you get the same results executing either /mnt/a.exe or \fast\dank\a.exe:

$ wine /mnt/a.exe
err:module:import_dll Library cygwin1.dll (which is needed by
L"Z:\mnt\a.exe") not found

$ wine '\fast\dank\a.exe'
err:module:import_dll Library cygwin1.dll (which is needed by
L"UNC\fast\dank\a.exe") not found

So that's great.  However, cmd doesn't support it:
$ wine cmd
CMD Version 0.9.59

Z:\home\dank>dir \fast\dank
Volume in drive Z is 
Volume Serial Number is 0000-0000

Directory of Z:\fast

File not found

See how it doesn't even recognize it's a UNC drive?

Likewise, Notepad can't browse to a UNC path.

Rob Shearman posted a patch this morning that seemed related,
http://www.winehq.org/pipermail/wine-patches/2008-April/053118.html
but that doesn't magically make Network Places show up in
Notepad's file dialog in my tests.
