87e7695873 new pos/bb funcs, legal(), better castling gen, etc. [see commit details]
- new sq_pinners
- new pseudo_is_legal() (unfinished)

  - bb_{rank,file,rel_rank,_sq_aligned,_sq_between)
- rename some bitboard globals
- replace bb ranks/files enums with defines (issue with clang)
  -> Need to find a way to use enum safely
- tests:
  - add common-test.h
  - new attack-test.c

  board.[ch]: everything related to board/square
  bitboard.[ch]: everything related to bitboards
  piece.[ch]: everything related to pieces
