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.

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.

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.

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.

e6e011baaf Add stream layer
The decoder initially read from the socket, decoded the video and sent
the decoded frames to the screen:

              +---------+      +----------+
  socket ---> | decoder | ---> |  screen  |
              +---------+      +----------+

The design was simple, but the decoder had several responsabilities.

Then we added the recording feature, so we added a recorder, which
reused the packets received from the socket managed by the decoder:

                                    +----------+
                               ---> |  screen  |
              +---------+     /     +----------+
  socket ---> | decoder | ----
              +---------+     \     +----------+
                               ---> | recorder |
                                    +----------+

This lack of separation of concerns now have concrete implications: we
could not (properly) disable the decoder/display to only record the
video.

Therefore, split the decoder to extract the stream:

                                    +----------+      +----------+
                               ---> | decoder  | ---> |  screen  |
              +---------+     /     +----------+      +----------+
  socket ---> | stream  | ----
              +---------+     \     +----------+
                               ---> | recorder |
                                    +----------+

This will allow to record the stream without decoding the video.

f5f4e6b1c5 Allocate extradata with av_malloc()
The extradata buffer is owned by libav, so it must be allocated with
av_malloc(), not SDL_malloc().

This fixes a crash on Windows during avformat_free_context().

477c0a2cab Create process with wide chars on Windows
Windows does not support UTF-8, so pushing a file with non-ASCII
characters failed.

Convert the UTF-8 command line to a wide characters string and call
CreateProcessW().

1aaad6ba35 Rescale packet timestamp to container time base
Some containers force their own time base. For example, matroska
overwrite time_base to (AVRational) {1, 1000}.

Therefore, rescale our packet timestamps to the output stream time base.
