Change the internal clipboard API to use a request based model in
order to be prepared for more advanced clipboard transfers.

We now filter incoming data, which means we can start assuming the
clipboard data is always null terminated. This allows us to clean
up a lot of the internal handling.

Do a proper cleanup when one of the termination timeouts trigger
rather than just exiting on the spot. This makes sure we don't leave
stray stuff around, e.g. unix socket files.

Make things simpler by making this a part of the SDesktop interface
that always needs to be implemented.

Applets don't work anymore so remove everything that has to do
with serving them.

It was only used by WinVNC, so push it there instead.

This adds the basic infrastructure and handshake for the QEMU
Extended Key Events extension. No viewer or server makes use of
the extra functionality yet though.

LED support added using Windows GetKeyState() API call.

The state is polled for change in CapsLock/NumLock/ScrollLock
status in the same code block where chages to Cursor shape is polled.

We have lots of code that deals with Windows versions that we no
longer support anyway. Clean out all of this old cruft.

We don't have any meaningful code for the mirror driver, so
remove the confusing stub and interface for it.

and the data flow is now more strictly aimed towards this connection class.
