[Qemu-devel] [PATCH] Share Vmware communication port between devices

Subject: [Qemu-devel] [PATCH] Share Vmware communication port between devices

VMware registers the port 0x5658 to communicate between guest and host.
At the moment, vmmouse.c is the only one to use this communication channel,
so it registers the port. IMO, this design is not right because it will be
hard to implement other functionalities of VMware.

I extracted non-mouse part from this file and created a framework for VMware
communication in a new file. Devices can then register for specific
commands, so communication port will be shared between devices.
I also added support for "Get RAM size" command. More commands will be added
