ec71a3f66a Use two sockets for video and control
The socket used the device-to-computer direction to stream the video and
the computer-to-device direction to send control events.

Some features, like copy-paste from device to computer, require to send
non-video data from the device to the computer.

To make them possible, use two sockets:
 - one for streaming the video from the device to the client;
 - one for control/events in both directions.

bfb86ca2c2 Simplify cleanup
The cleanup is not linear: for example, the server must be stopped and
its sockets must be shutdown after the stream and controller are stopped
(so that they don't continue processing garbage), but before they are
joined, to avoid a deadlock if they are blocked on a socket read.

Simplify the spaghetti-cleanup by keeping trace of initialization at
runtime.

5a431cdf9b Make server_connect_to() return a bool
The resulting socket is accessible from the server instance, there is no
need to return it.

This paves the way to use several sockets in parallel.

b941854c73 Disable X11 compositor bypass
Compositor bypass is meant for fullscreen games consuming lots of GPU
resources. For a light app that will usually be windowed, this only
causes unnecessary compositor suspends, especially visible (and
annoying) with complying window manager like KWin.

6baed8a06f Do not init SDL video subsystem if no display
The SDL video subsystem is not necessary if we don't display the video.

Move the sdl_init_and_configure() function from screen.c to scrcpy.c,
because it is not only related to the screen display.

163cd36ccc Rename -n/--no-window to -N/--no-display
The description of scrcpy is "Display and control your Android device".
We want an option to disable display, another one to disable control.

For naming consistency, name it --no-display.

Also change the shortname to -N, so that we can use -n for --no-control
later.

e6e011baaf Add stream layer
The decoder initially read from the socket, decoded the video and sent
the decoded frames to the screen:

              +---------+      +----------+
  socket ---> | decoder | ---> |  screen  |
              +---------+      +----------+

The design was simple, but the decoder had several responsabilities.

Then we added the recording feature, so we added a recorder, which
reused the packets received from the socket managed by the decoder:

                                    +----------+
                               ---> |  screen  |
              +---------+     /     +----------+
  socket ---> | decoder | ----
              +---------+     \     +----------+
                               ---> | recorder |
                                    +----------+

This lack of separation of concerns now have concrete implications: we
could not (properly) disable the decoder/display to only record the
video.

Therefore, split the decoder to extract the stream:

                                    +----------+      +----------+
                               ---> | decoder  | ---> |  screen  |
              +---------+     /     +----------+      +----------+
  socket ---> | stream  | ----
              +---------+     \     +----------+
                               ---> | recorder |
                                    +----------+

This will allow to record the stream without decoding the video.

d0e090e1f9 Reenable custom SDL signal handlers
This partially reverts commit f00c6c5b13.

On Ctrl+C, we need to execute cleanup code. For instance, if recording
is enabled, we need to write MP4 file trailer on exit.

Custom SDL signal handlers were disabled because it leaded to process
hanging on Ctrl+C during network calls on initialization, but now it
seems to work correctly, the network calls return immediately on signal.

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.

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.
