winspool: (EnumPorts #1) Read Driver from registry

[Detlef Riekenberg]

"localspl.dll" reached a state that allow us to use the
implemented Functions from other dlls.

After this set of Patches, "winspool.drv,EnumPortsW/A" is implemented 
(with tests) and use all installed Printmonitors.

Visible results for the Propsheet-Page "Ports" in printui.dll (native):
(13kb): http://www.myimg.de/?img=portsinprintuid05.png

"AddPort", "ConfigurePort" and "DeletePort" for winspool.drv 
are also "Ready to send" and gave us an working "Ports"-Page for

rundll32.exe printui.dll,PrintUIEntry /s


The Ports for the CUPS/LPR-Printers are not visible yet, because
they where never created. ("LoadSystemPrinters()" uses only AddPrinter)
This issue will be fixed, when the CUPS/LPR-Handling is moving 
to "localspl.dll"
