Romain Vimont ca767ba364 Group server params in a struct
Starting the server requires more and more parameters. For clarity,
group them in a struct.

Romain Vimont c8a6783494 Use positive options names internally
For clarity, store the flag resulting of the command-line options
--no-control and --no-display into "control" and "display".

Romain Vimont 5b56900e2b Rename unused field
The flag is used only in the server_start() implementation, there is no
need to store it in the structure.

Romain Vimont 8c8649cfcd Remove "turn device screen on" feature
Only keep "turn device screen off" and POWER button.

After we turn the device screen off (with Ctrl+o), turning it back on
does not always work, and leaves the device in a weird state, where even
the power button may not be sufficient:
<https://github.com/Genymobile/scrcpy/issues/175#issuecomment-497946596>

This is not an acceptable behavior, so disable the shortcut to turn the
physical device screen on. We can use the POWER button (or Ctrl+p)
instead.

Romain Vimont 41225c3e41 Improve key processing readability
The condition "event->type == SDL_KEYDOWN" and the variable
input_manager->controller are used many times. Replace them by local
variables to reduce verbosity.

Romain Vimont 12a3bb25d3 Implement device screen off while mirroring
Add two shortcuts:
 - Ctrl+o to turn the device screen off while mirroring
 - Ctrl+Shift+o to turn it back on

On power on (either via the POWER key or BACK while screen is off), both
the device screen and the mirror are turned on.

Romain Vimont 28980bbc90 Rename "event" to "message"
After the recent refactorings, a "control event" is not necessarily an
"event" (it may be a "command"). Similarly, the unique "device event"
used to send the device clipboard content is more a "reponse" to the
request from the client than an "event".

Rename both to "message", and rename the message types to better
describe their intent.

Romain Vimont c13a24389c Implement computer-to-device clipboard copy
It was already possible to _paste_ (with Ctrl+v) the content of the
computer clipboard on the device. Technically, it injects a sequence of
events to generate the text.

Add a new feature (Ctrl+Shift+v) to copy to the device clipboard
instead, without injecting the content. Contrary to events injection,
this preserves the UTF-8 content exactly, so the text is not broken by
special characters.

Romain Vimont 63c078ee6c Implement device-to-computer clipboard copy
On Ctrl+C:
 - the client sends a GET_CLIPBOARD command to the device;
 - the device retrieve its current clipboard text and sends it in a
   GET_CLIPBOARD device event;
 - the client sets this text as the system clipboard text, so that it
   can be pasted in another application.

Romain Vimont 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.

Romain Vimont 69360c7407 Extract control event string serialization
A string is serialized as a length (2 bytes) followed by the string data
(non nul-terminated).

For now, it is used only once, but we will need to serialize strings in
other events.

Romain Vimont 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.

Romain Vimont 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.

Romain Vimont 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.

The resulting socket is accessible from the server instance, there is no
