bfb3f0842f Prevent to turn screen off if no control
If --no-control is set, then the controller is not initialized (both in
the client and the server), so it is not possible to control the device
to turn its screen off.

See <https://github.com/Genymobile/scrcpy/issues/608>.

2755bfc255 Improve portable builds
In portable builds, scrcpy-server.jar was supposed to be present in the
current directory, so in practice it worked only if scrcpy was launched
from its own directory.

Instead, find the absolute path of the executable and build a suitable
path to use scrcpy-server.jar from the same directory.

3b17ff7c86 Add functions to convert wide char to UTF-8
There was already utf8_to_wide_char(), used to correctly execute
commands on Windows.

Add the reverse converter: utf8_from_wide_char(). We will need it to
build the scrcpy-server path based on the executable directory.

eb34098add Simplify portable build configuration
To create a portable build (with scrcpy-server.jar accessible from the
scrcpy directory), replace OVERRIDE_SERVER_PATH by a simple compilation
flag: PORTABLE.

This paves the way to use more complex rules to determine the path of
scrcpy-server.jar in portable builds.

b777760bca Simplify scrcpy-server path configuration

Instead, directly write the path in C.

72bdfbc7a6 Never return 0 for stream protocol
On socket disconnection, on Linux, recv() returns -1 and errno is set.
But on Windows, errno is 0.

In that case, AVERROR(errno) == 0, leading to the warning:

> Invalid return value 0 for stream protocol

To avoid the problem, if errno is 0, return AVERROR_EOF.

e2a272bf99 Improve framerate counting
The FPS counter was called only on new frames, so it could not print
values regularly, especially when there are very few FPS (when the
device surface does not change).

To the extreme, it was never able to display 0 fps.

Add a separate thread to print framerate every second.

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+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.
