* Added a net_timer::flags field, and used it to implement the new

wait_for_timer() function.
* Moved the internal Fifo class into utility.cpp - we should probably just
  remove it again.
* Fixed uninit_timers() so that it would even work in combination with the
  timer thread if there are timers left to be scheduled.
* Minor cleanup.
