0a7fe7ad57 Add helpers to truncate UTF-8 at code points
This will help to avoid truncating a UTF-8 string in the middle of a
code point, producing an invalid UTF-8 result.

63909fd10d Merge commands with other control events
Several commands were grouped under the same event type "command", with
a separate field to indicate the actual command.

Move these commands at the same level as other control events. It will
allow to implement commands with arguments.

3b4366e5bf Stop stream immediately on quit
If the stream is stopped, av_read_frame() will be woken up and yield a
corrupted packet. Do not try to decode or record it.

47f1003200 Close server socket before killing process
The sockets may be closed and shutdown on server_stop(). This will
interrupt the stream and controller threads more quickly and gracefully.

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.

8595862005 Use explicit output parameter for skipped frame
The function video_buffer_offer_decoded_frame() returned a bool to
indicate whether the previous frame had been consumed.

This was confusing, because we could expect the returned bool report
whether the action succeeded.

Make the semantic explicit by using an output parameter.

Also revert the flag (report if the frame has been skipped instead of
consumed) to avoid confusion for the first frame (the previous is
neither skipped nor consumed because there is no previous frame).

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.
