Implement BaseSrvDisconnect and BaseSrvCleanupVdmRecords, which will remove VDM console and DOS records
which have been left behind by a terminated ntvdm process.
Implement the "VDM voodoo" in BaseSrvCreateProcess. It's supposed to store the process ID of the VDM
in the VDM console record.
Fix minor bugs.
Add function declarations to the header file.
