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.

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.

The serialized text is not nul-terminated (its size is explicitely
provided), but the input text in the event is a nul-terminated string.
The test was failing with ASAN enabled.
The text input control_event was initially designed for mapping
SDL_TextInputEvent, limited to 32 characters.
For simplicity, the copy/paste feature was implemented using the same
control_event: it just sends the text to paste.
However, the pasted text might have a length breaking some assumptions:
- on the client, the event max-size was smaller than the text
max-length,
- on the server, the raw buffer storing the events was smaller than the
max event size.
Fix these inconsistencies, and encode the length on 2 bytes, to accept
more than 256 characters.

The video screen size on the client may differ from the real device
screen size (e.g. the video stream may be scaled down). As a
consequence, mouse events must be scaled to match the real device
coordinates.
For this purpose, make the client send the video screen size along with
the absolute pointer location, and the server scale the location to
match the real device size before injecting mouse events.
