Extract newgame character restrictions from newgame.cc.

The functions in the new ng-restr.cc are "pure": They don't
access global state; data is passed in via the new and
incomplete newgame_def.

Eventually, new_game should be split into something like
  newgame_def choose_game();
that doesn't access "you", and
  void setup_game(newgame_def);
that sets up the player.

Also get rid of player_size in favour of player::body_size. Rename
player_size_type to size_part_type since it's not really
player-specific (used in actor::body_size). Move parts of
player_genus, player::has_claws, body_size out into species.cc.
