2018-01-30backend: fix use-after-free when destroying backendsemersion
The backend destroy signal is emitted before the output_remove signal is. When the destroy signal is emitted listeners remove their output_remove listener, so the output_remove signal is never received and listeners have an invalid output pointer. The correct way to solve this would be to remove the output_remove signal completely and use the wlr_output.events.destroy signal instead. This isn't yet possible because wl_signal_emit is unsafe and listeners cannot be removed in listeners.

2017-08-16libinput: fail if no input found on initDominique Martinet
This runs through events pending at init on initialization so we can tell if some devices are available. Note that with the way wlr_device_lists is managed, this checks that there is at least one device we handle - it doesn't have to be a keyboard, but there is at least a mouse or tablet_pad or something that we care about. Instead of failing inconditionally it might be better to leave the decision to the user, e.g. add a "backend_has_devices" function to call later. (Tested by moving /dev/input off) Fixes #24.
