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.

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.

b35733edb6 Fix expected mouse event sizes
Commit fefb9816a9 modified mouse events
serialization. The server-side parsing was updated to correctly read the
position, but the expected size of these events was not updated.

As a result, the server might try to parse incomplete events, leading
to BufferUnderflowException.

39c5e71605 Make the server unlink itself
To clean up the device, the client executed "adb shell rm" once the
server was guaranteed to be started (after the connection succeeded).

This implied to track whether the installation state, and failed if an
additional tunnel was used in "forward" mode:
<https://github.com/Genymobile/scrcpy/issues/386#issuecomment-453936034>

Instead, make the server unlink itself on start.

fefb9816a9 Handle mouse events outside device screen
Mouse events position were unsigned (so negative values could not be
handled properly).

To avoid issues with negative values, mouse events outside the device
screen were ignored (commit a7fe9ad779).

But as a consequence, drag&drop were "broken" if the "drop" occurred
outside the device screen.

Instead, use signed 32-bits to store the position, and forward events
outside the device screen.

475912a39c Do not transmit MediaCodec flags
Since PTS handling has been fixed, the recorder do not associate a PTS
to a wrong frame anymore, so PTS of "configuration packets" (which never
produce a frame), are never read by the recorder. Therefore, there is no
need to ignore them explicitly, so we can remove the MediaCodec flags
completely.

c530d95881 Immediately close the server socket on the device
In "adb forward" mode, close the server socket as soon as the client is
connected.

Even if unlikely to be useful, it allows to run several instances of

1038bad385 Make it work over tcpip
"adb reverse" currently does not work over tcpip (i.e. on a device
connected by "adb connect"):
<https://issuetracker.google.com/issues/37066218>

To work around the problem, if the call to "adb reverse" fails, then
fallback to "adb forward", and reverse the client/server roles.

Keep the "adb reverse" mode as the default because it does not involve
connection retries: when using "adb forward", the client must try to
connect successively until the server listens.

Due to the tunnel, every connect() will succeed, so the client must
attempt to read() to detect a connection failure. For this purpose, when
using the "adb forward" mode, the server initially writes a dummy byte,
read by the client.

dac7196bd6 Support screens with dimensions not divisible by 8
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.

9396ea6d42 Fix text input event segfault
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.
