Now that the server can access the Android settings and clean up
properly, handle the "show touches" option from the server.
The initial state is now correctly restored, even on device
disconnection.
Add Ctrl+Left and Ctrl+Right shortcuts to rotate the display (the
content of the scrcpy window).
Contrary to --lock-video-orientation, the rotation has no impact on
recording, and can be changed dynamically (and immediately).
Fixes#218 <https://github.com/Genymobile/scrcpy/issues/218>
Accept a range of ports to listen to, so that it does not fail if
another instance of scrcpy is currently starting.
The range can be passed via the command line:
scrcpy -p 27183:27186
scrcpy -p 27183 # implicitly 27183:27183, as before
The default is 27183:27199.
Closes#951 <https://github.com/Genymobile/scrcpy/issues/951>
A proper solution could be to use "long long" instead (guaranteed to be
at least 64 bits), but it adds its own problems (e.g. "%lld" is not
supported as a printf format on all platforms).
In practice, we don't need such high values, so keep it simple.
Fixes#995 <https://github.com/Genymobile/scrcpy/issues/995>
