o The if_change_too_big_p change was too high-spirited. Fixed.

o  Introduced if_find_by_index()
o  Recognizing two types of interface updates: full update (starting with
   if_start_update(), ending with if_end_update(), guaranteed to see
   all existing interfaces) and a partial update (only if_update(),
   usually due to asynchronous interface notifications).
