dd2a5c1ecf Disable "show touches" once window is closed
If --show-touches is set, then the option must be disabled on quit.

Since it executes an adb command, it takes some time, so close the
window beforehand so that the close window button does not seem
unresponsive.

0b1e59186f Workaround continuous resizing on Windows/MacOS
On Windows and MacOS, resizing blocks the event loop, so resizing events
are not triggered:
 - <https://bugzilla.libsdl.org/show_bug.cgi?id=2077>
 - <https://stackoverflow.com/a/40693139/1987178>

As a workaround, register an event watcher to render the screen from
another thread.

Since the whole event loop is blocked during resizing, the screen
content is not refreshed (on Windows and MacOS) until resizing ends.

1038bad385 Make it work over tcpip
"adb reverse" currently does not work over tcpip (i.e. on a device
connected by "adb connect"):
<https://issuetracker.google.com/issues/37066218>

To work around the problem, if the call to "adb reverse" fails, then
fallback to "adb forward", and reverse the client/server roles.

Keep the "adb reverse" mode as the default because it does not involve
connection retries: when using "adb forward", the client must try to
connect successively until the server listens.

Due to the tunnel, every connect() will succeed, so the client must
attempt to read() to detect a connection failure. For this purpose, when
using the "adb forward" mode, the server initially writes a dummy byte,
read by the client.

Fixes <https://github.com/Genymobile/scrcpy/issues/5>.

2b3ed5bcdb Store serial in server instance
The serial is needed for many server actions, but this is an
implementation detail, so the caller should not have to provide it on
every call.

Instead, store the serial in the server instance on server_start().

9396ea6d42 Fix text input event segfault
The text input control_event was initially designed for mapping
SDL_TextInputEvent, limited to 32 characters.

For simplicity, the copy/paste feature was implemented using the same
control_event: it just sends the text to paste.

However, the pasted text might have a length breaking some assumptions:
 - on the client, the event max-size was smaller than the text
   max-length,
 - on the server, the raw buffer storing the events was smaller than the
   max event size.

Fix these inconsistencies, and encode the length on 2 bytes, to accept
more than 256 characters.

db396f2138 Fix scroll wheel mouse position
SDL_MouseWheelEvent does not provide the mouse location, so we used
SDL_GetMouseState() to retrieve it.

Unfortunately, SDL_GetMouseState() returns a position expressed in the
window coordinate system while the position filled in SDL events are
expressed in the renderer coordinate system. As a consequence, the
scroll was not applied at the right position on the device.

Therefore, convert the coordinate system.

c78ad6377c Terminate the server on stop
On user request to quit, two kinds of blocking calls must be interrupted
on the server:
 1. the reads from and writes to the socket;
 2. the call to MediaCodec.dequeueOutputBuffer().

The former case was handled by calling shutdown() on the socket from the
client, but the latter was not managed.

There is no easy way to wake this call properly, so just terminate the
process from the client (i.e. send SIGTERM on Linux) instead.

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.

The client was built with Meson, the server with Gradle, and were run by

Add a Meson script for the server (which delegates to Gradle), and a

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

device, since it blocks the event loop, preventing to react to SIGTERM
(Ctrl+C).

90a46b4c45 Improve startup time
On startup, the client has to:
 1. listen on a port
 2. push and start the server to the device
 3. wait for the server to connect (accept)
 4. read device name and size
 5. initialize SDL
 6. initialize the window and renderer
 7. show the window

From the execution of the app_process command to start the server on the
device, to the execution of the java main method, it takes ~800ms. As a
consequence, step 3 also takes ~800ms on the client.

Once complete, the client initializes SDL, which takes ~500ms.

These two expensive actions are executed sequentially:

                     HOST              DEVICE
listen on port        |                  |
push/start the server |----------------->|| app_process loads the jar
accept the connection .   ^              ||
                      .   |              ||
                      .   | WASTE        ||
                      .   |  OF          ||
                      .   | TIME         ||
                      .   |              ||
                      .   |              ||
                      .   v              X execution of our java main
connection accepted   |<-----------------| connect to the host
init SDL             ||                  |
                     || ,----------------| send frames
                     || |,---------------|
                     || ||,--------------|
                     || |||,-------------|
                     || ||||,------------|
init window/renderer  | |||||,-----------|
display frames        |<++++++-----------|
(many frames skipped)

The rationale for step 3 occuring before step 5 is that initializing
SDL replaces the SIGTERM handler to receive the event in the event loop,
so pressing Ctrl+C during step 5 would not work (since it blocks the
event loop).

But this is not so important; let's parallelize the SDL initialization
with the app_process execution (we'll just add a timeout to the
connection):

                     HOST              DEVICE
listen on port        |                  |
push/start the server |----------------->||app_process loads the jar
init SDL             ||                  ||
                     ||                  ||
                     ||                  ||
                     ||                  ||
                     ||                  ||
                     ||                  ||
accept the connection .                  ||
                      .                  X execution of our java main
connection accepted   |<-----------------| connect to the host
init window/renderer  |                  |
display frames        |<-----------------| send frames
                      |<-----------------|

In addition, show the window only once the first frame is available to
avoid flickering (opening a black window for 100~200ms).

Note: the window and renderer are initialized after the connection is
accepted because they use the device information received from the
device.

4662198261 Do not release TCP sockets while still in use
SDLNet_TCP_Close() not only closes, but also release the resources.

Therefore, we must not close the socket if another thread attempts to
read it.

For that purpose, move socket closing from server_stop() to
server_destroy().

7458d8271e Kill the server immediately on close
Do not wait 100ms anymore to let the server print any exception: we
justly want to ignore them.

Moreover, there is no nanosleep() on Windows, so this solve another
problem.

2fdc368c41 Do not try to decode video when EOF is reached
When the video stream socket is closed and read_packey() returns -1,
av_read_frame() still returns 0.

To detect EOF, check the flag eof_reached in the AVIOContext.

This avoids garbage errors on closing.
