nodedev: udev: Split udevEventHandleCallback in two functions

Browse Source 
This patch splits udevEventHandleCallback in two (introduces
udevEventHandleThread) in order to be later able to refactor the latter
to actually become a normal thread which will wait some time for the
kernel to create the whole sysfs tree for a device as we cannot do that
in the event loop directly.
