Modifier or other key events are still sent by some compositors after leaving the window which causes them to be pressed on both devices.
Now an Enter event must be produced before any further events are sent out (except disconnect)
Keys are now released when
- A client disconnects and still has pressed keys
- A client disconnects through CTLR+ALT+SHIFT+WIN
- Lan Mouse terminates with keys still being pressed through a remote client
This is also fixes an issue caused by KDE's implementation of the remote desktop portal backend:
Keys are not correctly released when a remote desktop session is closed while keys are still pressed,
causing them to be permanently stuck until kwin is restarted.
This workaround remembers all pressed keys and releases them when lan-mouse exits or a device disconnects.

Instead of relying on release events not getting lost, every event now signals the opponent
to release its pointer grab.
There is one case that requires a Leave event:
Consider a Sending client A and receiving Client B.
If B enters the dead-zone of client A, it will send an enter event towards A but before
A receives the Release event, it may still send additional events towards B that should not cause
B to immediately revert to Receiving state again.
Therefore B puts itself into AwaitingLeave state until it receives a Leave event coming from A.
A responds to the Enter event coming from B with a leave event, to signify that it will no longer
send any events and releases it's pointer.
To guard against packet loss of the leave events, B sends additional enter events while it is in AwaitingLeave
mode until it receives a Leave event at some point.
This is still not resilient against possible packet reordering in UDP but in the (rare) case where a leave event arrives before some other event coming from A, the user would simply need to move the pointer into the dead-zone again.
* macos: initial support
- adapted conditional compilation
- moved lan-mouse socket to ~/Library/Caches/lan-mouse-socket.sock instead of XDG_RUNTIME_DIR
- support for mouse input emulation
TODO: Keycode translation, input capture
major update:
- remove threading overhead by resorting to an event driven design with mio as a backend for epoll
- Clients can now have an arbitrary amount of ip adresses and lan-mouse will automatically choose the correct one
- -> seemless switching between ethernet and wifi
- cli frontend + frontend adapter for future frontends
