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.

2c4ea6869e Do not use device as a singleton 
The device instance should be able to store a state (e.g. the maximum
size requested by the user), so it should not be a singleton.

879941355d Swap position/point names 
A point is a 2D vector. A position represent a point relative to the
screen size.

on some devices.

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.

11a60e5767 Keep screen info in cache 
Currently, we only use screen information (width, height, rotation)
once at initialization, to send the device size to the client.

To be able to scale mouse events, make it accessible in memory. For this
purpose, replace the "static" DeviceUtil to a singleton Device, and
update it on every screen rotation.

functions to push the jar and enable/disable the "adb reverse" tunnel.

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.

bug). To avoid a segmentation fault, do not call SDL_Quit().

1a71c4ab1d Implement framework wrappers separately

separate package (".wrappers").

This paves the way to implement InputManager properly.
