RawDevice would deadlock in some situations because I/O occured while
the listener was turning on. This also seems to have fixed logid
sometimes not detecting devices on receivers.
Many changes were made here but that was the biggest one.
There's currently a bug where std::system_error: Broken pipe is thrown
after launching the daemon with a receiver connector.
A workaround for this bug is to simply shake the mouse while starting
the daemon. I will investigate this soon.
Multiple things have been done in this commit; the base of the new
backend has effectively been created. This branch currently has many
vital parts commented out. Therefore, this branch is currently only
intended for debugging.
