Function dgn_reset_player_data

crawl-ref/source/dungeon.cc:749–794

It's probably better in general to just reset `you` instead of calling this. But that's not so convenient for some users of this function, notably lua tests. This leaves some state uninitialized, and probably should be immediately followed by a call to `initial_dungeon_setup` and something that moves the player to a level or regenerates a level. */
