The codec only supports dimensions which are multiple of 8.
Thus, when --max-size is specified, the value is always rounded down to
the nearest multiple of 8.
However, it was wrongly assumed that the physical size is always a
multiple of 8. To support such devices, also round down the physical
screen dimensions.

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.

Paste computer clipboard to the device on Ctrl+v.
The other direction (pasting the device clipboard to the computer) is
not implemented. It would require a communication channel from the
device to the computer, other than the socket used by the video stream.
No exception was thrown on EOF, so the event controller did not
terminate. This leaded to a further InvocationTargetException.
Instead, terminate the event controller on EOF, so that the process
terminates properly.
Characters like 'é' or 'î' are not resolved by getEvents(). For example,
getEvents("é") returns null.
However, it is possible to decompose them. For example,
getEvents("\u0301e") returns the events generating "é".
Thank you Philippe! ;)
In handleEvent(), connection.receiveControlEvent() may never return
null: either it returns a valid ControlEvent, either it throws an
Exception.
Therefore, there is no need to propagate a flag to indicate whether it
returned a valid ControlEvent.
On some devices, we can reuse the same codec and display, but on some
others (e.g. Nexus 5X with Android 7.1.2), it crashes on codec.stop()
with an IllegalStateException.
Therefore, always recreate the codec and display, so that it works on
all devices.
The right-click is almost useless on Android, so use it to turn the
screen on.
Add a new control event type (command) to request the server to turn the
screen on.
Replace screenrecord execution by manual screen encoding using the
MediaCodec API.
The "screenrecord" solution had several drawbacks:
- screenrecord output is buffered, so tiny frames may not be accessible
immediately;
- it did not output a frame until the surface changed, leading to a
black screen on start;
- it is limited to 3 minutes recording, so it needed to be restarted;
- screenrecord added black borders in the video when the requested
dimensions did not preserve aspect-ratio exactly (sometimes
unavoidable since video dimensions must be multiple of 8);
- rotation handling was hacky (killing the process and starting a new
one).
Handling the encoding manually allows to solve all these problems.
