9b056f5091 Replace SDL_net by custom implementation
SDL_net is not very suitable for scrcpy.

For example, SDLNet_TCP_Accept() is non-blocking, so we have to wrap it
by calling many SDL_Net-specific functions to make it blocking.

But above all, SDLNet_TCP_Open() is a server socket only when no IP is
provided; otherwise, it's a client socket. Therefore, it is not possible
to create a server socket bound to localhost, so it accepts connections
from anywhere.

This is a problem for scrcpy, because on start, the application listens
for nearly 1 second until it accepts the first connection, supposedly
from the device. If someone on the local network manages to connect to
the server socket first, then they can stream arbitrary H.264 video.
This may be troublesome, for example during a public presentation ;-)

Provide our own simplified API (net.h) instead, implemented for the
different platforms.

000ced9ba8 Refactor screencontrol to inputmanager
The "screen control" handled user input, which happened to be only
used to control the screen.

The controller and screen were passed to every function. Instead, group
them in a struct input_manager.

The purpose is to add a new shortcut to enable/disable FPS counter. This
feature is not related to "screen control", and will require access to
the "frames" instance.

42882702d7 Expose skip_frames as a build option
It can be initially configured by:

    meson builddir -Dskip_frames=false

Or on an existing builddir by:

    mesonconf builddir -Dskip_frames=false

0efa9305eb Require Meson 0.37
Older versions of Meson are too limited, and it's simple to install a
newer version ("pip3 install meson").

c2127d0819 Replace meson subprojects by subdir
Since Meson 0.44, subproject_dir may not be '.' anymore. This implies we
must move app/ and server/ to a subprojects/ directory, which requires
to also change some gradle files.

Instead, just use subdir(), with options to disable building of the app
or the server.

ff94462d8a Refactor build system
The client was built with Meson, the server with Gradle, and were run by
a Makefile.

Add a Meson script for the server (which delegates to Gradle), and a
parent script to build and install both the client and the server to the
system, typically with:

    meson --buildtype release build
    cd build
    ninja
    sudo ninja install

In addition, use a separate Makefile to build a "portable" version of
the application (where the client expects the server to be in the
current directory). Typically:

    make release-portable
    cd dist/scrcpy
    ./scrcpy

This is especially useful for Windows builds, which are not "installed".

396df8a9d8 Provide config.h.in for old meson versions
The current meson version is able to generate a config.h from a
configuration data object without any template.

However, older versions of meson require a template, so provide it for
compatibility.

6c578b5caa Move screen-related code to screen.c
The file scrcpy.c contains too many different things in addition to the
main logic, so move the screen code to a separate file, screen.c.

8d30d40b79 Make SKIP_FRAMES a compilation flag
The skip_frames flag was a non-configurable runtime flag. Since it is
not exposed to the user, there is no need for a (possible) runtime cost.

For testing purpose, we still want it to be configurable, so make it a
compilation flag.

71c2bfdd22 Parse XPM without SDL_image
We encounter some problems with SDL2_image on MSYS2 (Windows), so
implement our own XPM parsing which does not depend on SDL_image.

The input XPM is considered safe (it's in our source repo), so do not
check XPM format errors. This implies that read_xpm() is not safe to
call on any unsafe input.

Although less straightforward, use SDL_CreateRGBSurfaceFrom() instead of
SDL_CreateRGBSurfaceWithFormatFrom() because it is available with SDL
versions older than 2.0.5.

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.
