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).

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.

e2b3968c66 Always synchronize clipboard on explicit COPY/CUT
If --no-clipboard-autosync is enabled, the automatic clipboard
synchronization performed whenever the device clipboard changes is
disabled.

But on explicit COPY and CUT scrcpy shortcuts (MOD+c and MOD+x), the
clipboard should still be synchronized, so that it remains possible to
copy-paste from the device to the computer.

This is consistent with the behavior of MOD+v, which pastes the computer
clipboard to the device.

There are two variants:
 - If a destination address is provided, then scrcpy connects to this
   address before starting. The device must listen on the given TCP port
   (default is 5555).
 - If no destination address is provided, then scrcpy attempts to find
   the IP address of the current device (typically connected over USB),
   enables TCP/IP mode, then connects to this address before starting.

5d17bcf1bc Wait SET_CLIPBOARD ack before Ctrl+v via HID
To allow seamless copy-paste, on Ctrl+v, a SET_CLIPBOARD request is
performed before injecting Ctrl+v.

But when HID keyboard is enabled, the Ctrl+v injection is not sent on
the same channel as the clipboard request, so they are not serialized,
and may occur in any order. If Ctrl+v happens to be injected before the
new clipboard content is set, then the old content is pasted instead,
which is incorrect.

To minimize the probability of occurrence of the wrong order, a delay of
2 milliseconds was added before injecting Ctrl+v. Then 5ms. But even
with 5ms, the wrong behavior sometimes happens.

To handle it properly, add an acknowledgement mechanism, so that Ctrl+v
is injected over AOA only after the SET_CLIPBOARD request has been
performed and acknowledged by the server.

443cb14d6e Assume non-NULL serial in file_handler
The previous commit guarantees to always initialize the serial, so the
file_handle may assume it is never NULL.

b30c3a429f Always retrieve device serial
This allows to execute all adb commands with the specific -s parameter,
even if it is not provided by the user.

In practice, calling adb without -s works if there is exactly one device
connected. But some adb commands (for example "adb push" on drag & drop)
could be executed after another device is connected, so the actual
device serial must be known.

632bd5697b Add missing error handling

de50846905 Close process on check success
The interruptible version of the function to check process success
(sc_process_check_success_intr()) did not accept a close parameter to
avoid a race condition. But as the result, the processes were not closed
at all.

Add a close parameter, and close the process separately to avoid the
race condition.

9cb14b5166 Inherit only specific handles on Windows
To be able to communicate with a child process via stdin, stdout and
stderr, the CreateProcess() parameter bInheritHandles must be set to
TRUE. But this causes *all* handles to be inherited, including sockets.

As a result, the server socket was inherited by the process running adb
to execute the server on the device, so it could not be closed properly,
causing other scrcpy instances to fail.

To fix the issue, use an extended API to explicitly set the HANDLEs to
inherit:
