c996a6d462 Fix socket close race condition
The server needs to interrupt the sockets on stop, but it must not close
them while other threads may attempt to read from or write to them.

In particular, the video_socket is read by the stream thread, and the
control_socket is written by the controller and read by receiver.

Therefore, close the socket only on sc_server_destroy(), which is called
after all other threads are joined.

Reported by TSAN on close:

75c5dc6859 Position and size the window on first frame
The optimal initial size was computed from the expected dimensions, sent
immediately by the server before encoding any video frame.

However, the actual frame size may be different, for example when the
device encoder does not support the requested size.

To always handle this case properly, position and size the window only
once the first frame size is known.

server.

Keep the old FFmpeg prebuilt binaries (4.3.1) for win32 builds.

17d01b5bf7 Add UI/UX support for relative mouse mode
In relative mouse mode, the mouse pointer must be "captured" from the
computer.

Toggle (disable/enable) relative mouse mode using any of the hardcoded
capture keys:
 - left-Alt
 - left-Super
 - right-Super

These capture keys do not conflict with shortcuts, since a shortcut is
always a combination of the MOD key and some other key, while the
capture key triggers an action only if it is pressed and released alone.

The relative mouse mode is also automatically enabled on any click in
the window, and automatically disabled on focus lost (it is possible to
lose focus even without the mouse).
