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.

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).

b5855e5deb Add relative mode flag to mouse processors

at a specific position on screen.

To support HID mouse, add a flag to indicate that the mouse processor

absolute reference to the screen.

924375487e Pass buttons state in scroll events
A scroll event might be produced when a mouse button is pressed (for
example when scrolling while selecting a text). For consistency, pass
the actual buttons state (instead of 0).

In practice, it seems that this use case does not work properly with
Android event injection, but it will work with HID mouse.

6102a0b5bb Move input_manager into screen
The input_manager is strongly tied to the screen, it could not work
independently of the specific screen implementation.

To implement a user-friendly HID mouse behavior, some SDL events
will need to be handled both by the screen and by the input manager. For
example, a click must typically be handled by the input_manager so that
it is forwarded to the device, but in HID mouse mode, the first click
should be handled by the screen to capture the mouse (enable relative
mouse mode).

Make the input_manager a descendant of the screen, so that the screen
decides what to do on SDL events.

Concretely, replace this structure hierarchy:

     +- struct scrcpy
        +- struct input_manager
        +- struct screen

by this one:

     +- struct scrcpy
        +- struct screen
           +- struct input_manager

ddb9396743 Interrupt and close sockets on server stop
The sockets were never interrupted or closed by the client since recent
changes to run the server from a dedicated thread (see commit
0426708544).

As a side effect, the server could never terminate properly (it was
waiting on socket blocking calls), so it was always killed by the client
after the WATCHDOG_DELAY.

Interrupt the sockets on stop to give the servera chance to terminate
property, then close them.

cabcbc2b15 Do not create control socket if no control

This also facilitates the use of the server alone (without the client)
to receive only the raw video stream.
