		char *	keycode,

	)

Places keys in the map, preferably in something alive.

The idea is that you call keyplace on x,y where a door is, and it'll make sure a key is placed on both sides of the door.

Parameters

map
x
y	where to put a key.
keycode	keycode is the key's code.
door_flag	if NO_PASS_DOORS won't cross doors or walls to keyplace, PASS_DOORS will. if PASS_DOORS is set, the x & y values that are passed in are basically meaningless - IMO, it is a bit of misnomer, as when it is set, it just randomly chooses spaces on the map, ideally finding a close monster, to put the key in. In fact, if PASS_DOORS is set, there is no guarantee that the keys will be on both sides of the door - it may happen by randomness, but the code doesn't work to make sure it happens.
n_keys	number of keys to place. If 1, it will place 1 key. Else, it will place 2-4 keys.
RP	random map parameters.

Returns

1 if key was successfully placed, 0 else.

int load_dir	(	const char *	dir,
		char ***	namelist,
		int	skip_dirs
	)

This is our own version of scandir/select_regular_files/sort. To support having subdirectories in styles, we need to know if in fact the directory we read is a subdirectory. However, we can't get that through the normal dirent entry. So instead, we do our own where we do have the full directory path so can do stat calls to see if in fact it is a directory. dir is the name of the director to scan. namelist is the array of file names returned. IT needs to be freed by the caller. skip_dirs controls our behavioru - if nonzero, we don't skip any subdirectories - if zero, we store those away, since there are cases where we want to choose a random directory.

Parameters

	dir	directory to list.
[out]	namelist	list of files found.
	skip_dirs	if non 0, don't list directories.

Returns

-1 if dir is invalid, number of files else.
