- add many "const" in func parameters - attack.c: sq_attackers() - move print_board_raw from position.c to to board.c - move some fen_check() tests to pos_check() - add REL_RANK() macro. TODO: add one more for bitboards - fen.c: more tests for FEN validity - position.c: add pos_checkers() and pos_check() - tests: add common-test.h (for shared FEN positions access)
