[LOCALMON]

[LOCALMON]
- Bugfix: LocalmonClosePort must only free the memory for virtual file ports. Other port entries are reused.
- Bugfix: Set the port type to PortType_OtherLPT in all conditions that ít's not a physical LPT port.
- Synchronize access to the port lists.
- Keep a list of open Xcv handles as well to properly close them on shutdown.
- Add traces to all monitor functions for easier debugging. (requires DEBUGCHANNEL=+localmon environment variable)
