bugfix_1_7.1. Use standard C. 
arend_3_7.5. Blunder more carefully. 
gunnar_3_7.7. Two bugfixes. 
matcher_check_3_7.7. One more matcher_check fix. 
evan_3_7.2. New test. (See strategy5:272.) 
pogonyshev_3_7.1. Not EXPERIMENTAL_CONNECTIONS. 
tuning_3_7.1. Minor tuning. 
safety_3_7.1. New tests. 
matcher_check_3_7.7b. Stable option.

- write "forced" as comment when this ascii mode command is used
- sgftree_readfile does not change root node to NULL
- new blunder_size(), atari_atari_blunder_size() compute the blunder size
- remove vital_string logic in atari_atari code
- remove allowed_blunder_size heuristic in review_move_reasons()

- new function test_attack_either_move; gets invoked by patterns
  instead of directly adding the attack-either move reason
- new function mark_changed_dragon() in move_reasons.c
- only mark owl defended stones as safe if also sufficiently tactically safe
- matcher_check can analyze existing sgf files
- twogtp-a kills processes
- break_chain2_moves() revised
- placehand() renamed to place_fixed_handicap()
- new function place_free_handicap() in handicap.c with associated

- new pattern database handicap.db
- new autohelper macros handicap_stones, total_handicap_stones for handicap.db
- mkpat.c revised to avoid compiler warnings for constraints using no labels
