[PATCH] udevd - cleanup and better timeout handling

Here is the next revision for udevd:
  o Small cleanups all over the place.
  o Swich to the usual linked list format "list.h".
  o Better timeout handling.
      We store a timestamp in in every queued event, so we don't wait longer
      than the timeout specified, if the hole in the list is not shrinking.
  o ignore udevd target if klibc is used
