grab all input devices

[ardera]

use EVIOCGRAB to grab all input devices for exclusive use.
otherwise, if people have a keyboard attached and a console running, the keyboard can be used to enter things on the console.

See discussion in #256

And how do I use it?

Since the latest Binary update to Flutter 3.3.7 the keyboard input doesn't work anymore in my Flutter App. It only appears in the console.

@niklasbartsch Should work OOB. If it doesn't, could be libinput exposes your keyboard as both a key and pointer device, and at least in the master branch, that case isn't handled correctly yet.

Though it's handled correctly on the feature/compositor-ng branch, can you try there and lmk if it works?

[niklasbartsch]

Still doesn't work, event with the feature/compositor-ng Branch

@niklasbartsch That's a bug then, can you run libinput debug-events, press some keys, and send me the complete output? And what does your flutter-pi output look like?

Also please open a new issue for that (and post the logs there)

I opened the Issue #304.
How do I use libinput debug-events?

I know, it's really annoying when the keyboard inputs also appear on the console.
Let's say you have a login screen, and some users know that they can close the app with Ctrl+C, that would be a security issue.

In my case, I create an autorun script to run my app. So I can use stty -echo command as a workaround. See this SO answer.
