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.

If --no-control is requested, then the controller instance is not
initialized. However, its reference was still passed to screen and
input_manager.
Instead, pass NULL if no controller is available.
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.
PR #2947 <https://github.com/Genymobile/scrcpy/pull/2947>
Show the window only after the actual frame size is known (and if no
error has occurred).
This will allow to properly position and size the window when the size
of the first frame is different from the size initially announced by the
server.

The components should be configurable independently of the global
scrcpy_options instance: their configuration could be provided
separately, like it is the case for example for some screen parameters.
For consistency, keyboard injection should not depend on scrcpy_options.
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).
The decision to not send motion events when no click is pressed is
specific to Android mouse injection. Other mouse processors (e.g. for
HID mouse) will need to receive all events.
The default mouse injection works in absolute mode: it forwards clicks
at a specific position on screen.
To support HID mouse, add a flag to indicate that the mouse processor
works in relative mode: it forwards mouse motion vectors, without any
absolute reference to the screen.
