Hermès Bélusca-Maïto e1ef078741 Create this branch to work on loading of different Kernel-Debugger DLL providers, and see whether it is possible to move KDBG from ntoskrnl to a new DLL called, say, KDROSDBG.DLL.
The idea then would be to have the following behaviour (when specifying the following options in the kernel command line):

/DEBUGPORT=COMi --> load KDCOM.DLL and use COMi port (i == 1,2,3,4) if possible.
/DEBUGPORT=FOO  --> load KDFOO.DLL (useful for KDUSB.DLL, KD1394.DLL, KDBAZIS.DLL for VirtualKD, etc...)
/DEBUGPORT=ROSDBG:[COMi|SCREEN|FILE|GDB|...] --> load KDROSDBG.DLL which contains the ROS kernel debugger, and use COMi or SCREEN or... as output port.
