This patch, as well as the more recent revision, has one significant
problem, namely that the dragon data is modified from within the move
valuation. Experience has shown that this is a bad idea. All dragon
status and other data should be established during examine_position()
and only be read in the move valuation.
I.e. if a dragon status is incorrect, that needs to be detected in
advance of the move valuation, preferably in make_dragons().
