When coyright text is changed, autotools must be run after all

other actions, as otherwise timestamps of "config.h.in" will 
cause re-run on compilation machine (fatal version problem!).


Build-tools/mysql-copyright:
  1) Ensure that autotools are run as last action, after copyright
  change, for proper timestamps.
  2) Move the trimming of subtrees to an own function "trim_the_fat".
  3) Align 4.0 and 4.1 versions.
