000c70a644 Decompose accented characters
Characters like 'é' or 'î' are not resolved by getEvents(). For example,
getEvents("é") returns null.

However, it is possible to decompose them. For example,
getEvents("\u0301e") returns the events generating "é".

Thank you Philippe! ;)

0fce4f95b9 Properly clean up on exit
The SDL clean up does not crash anymore on exit, probably since the
memory corruption caused by calling SDLNet_TCP_Close() too early has
been resolved.

eb09fefd43 Timeout the server socket connection
Wait no more than 2 seconds for accepting the connection from the
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.

c683872bbc Avoid server stacktraces on close
On close, the socket is closed by the client, and the server process is
killed.

This leads to (expected) exceptions, that should not be printed.

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.

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.
