Use a classic pseudo-random hashing approach, by multiplication of chunk numbers
with large primes that should be more random.
- make slime density (as 1 in N) and maximum light level (default: no limit) configurable
- Allow using a 3d chunking system where y is also used for hashing
This does *not* modify spawn frequency, only the chunk logic.

Sometimes, pools would spawn deep underground and then produce deep holes.
I noticed that such pools would be at +48, at the block boundary.
IMHO this may be an error in minetest surface detection.
Nevertheless, here is a workaround: require air above pool spawns.
Also clean up the pool code

Placing the texture at -16 with width 16 means it is not used. At most -14 may be used (0 indexed, I believe) if you want to retain 2x2 pixels.

This adds defensive checks to guard against crashing when digging with an unknown item in hand.

As spawning happens via gennotify anyway, we can omit placing a
structblock right away.
This also avoids certain cases of holes in snow cover or water.
Plus, the code is simpler.
Isolated from the big mapgen overhaul, for the main branch.
