ad55a9addc Prefix server logs 
Sometimes, it is not obvious whether a log is generated by the server or
by the client. Prefix server logs for clarity.

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.

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.

2322069656 Extract control event String parsing 
Parsing a String from a serialized control event, encoded as length (2
bytes) + data, will be necessary in several events.

Extract it to a separate method.

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.

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.

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.

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.

47f1003200 Close server socket before killing process

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

need to return it.

This paves the way to use several sockets in parallel.
