ca44585f96 Do not send simple mouse move events 
Moving the mouse without any button pressed has no effect on Android.
Therefore, do not even send these very frequent events.

274e1ac9ec Fix rotation bug in fullscreen mode on X11 
On rotation, scrcpy resize the window to match the new rotation.
However, in fullscreen mode, setting the window size does not change the
windowed size on X11, so the behavior is incorrect.

To avoid the problem, apply the resize only after fullscreen is
disabled.

60b2f2ca64 Indent switch blocks content 
For readability, indent "case" in switch blocks.

Replace:

    switch (x) {
    case 1:
        // ...
    case 2:
        // ...
    case 3: { // a local scope block
        int i = 42;
        // ...
    }
    }

By:

    switch (x) {
        case 1:
            // ...
        case 2:
            // ...
        case 3: { // a local scope block
            int i = 42;
            // ...
        }
    }

b67907e24e Convert server to an Android project 
To simplify the device server-side build, use gradle to create an APK,
even if we use it as a simple jar, by running its main() method.

89f6a3cfe7 Handle resized video stream 
Accept a parameter to limit the video size.

For instance, with "-m 960", the great side of the video will be scaled
down to 960 (if necessary), while the other side will be scaled down so
that the aspect ratio is preserved. Both dimensions must be a multiple
of 8, so black bands might be added, and the mouse positions must be
computed accordingly.

2c35220618 Rename screen -> scrcpy -> main 
Rename scrcpy.c to main.c (this file handles the command line parsing),
and screen.c to scrcpy.c (it exposes the entry point scrcpy()).

8984c1a7c4 Scale mouse events 
The video screen size on the client may differ from the real device
screen size (e.g. the video stream may be scaled down). As a
consequence, mouse events must be scaled to match the real device
coordinates.

For this purpose, make the client send the video screen size along with
the absolute pointer location, and the server scale the location to
match the real device size before injecting mouse events.

53cd59605a Ignore keycodes generating unwanted events 
Ctrl, Alt, Shift and Meta should not be transmitted to the Android
device: they may generate unwanted events. For instance, resizing the
window using Alt+click will generate an Alt event which may open a menu
on the device.

All keycodes that generate a text input must also be excluded, to avoid
the text input to be written twice.

cabb102a04 Implement keyboard/mouse control 
To control the device from the computer:
 - retrieve mouse and keyboard SDL events;
 - convert them to Android events;
 - serialize them;
 - send them on the same socket used by the video stream (but in the
 opposite direction);
 - deserialize the events on the Android side;
 - inject them using the InputManager.

a919944372 Use _exit() instead of exit() in child process 
exit() should not be called from within a child process, since it would
call functions registered with atexit(), and flush stdio streams. Use
_exit() instead.
