Adds a (new) mcl_structures.register_structure(name,def) command.

The old register_structure thing was renamed to structure_data - the only thing it has been used for is to store the locations of strongholds.

Also adds dynamically generated geodes and surface pools (lava pools and lakes) as a test for the placement by function option.

It supports /spawnstruct now so you can test placement by using that.

Shipwrecks and geodes are using this right now but I hope to get some or hopefully most of the legacy structures to use this. But since this is 100% compatible there's no need to rush. mcl_mapgen_core is going to be a bit of a task to untangle hehe.

Testing

Use seed "y" for testing:

-20,1,160 - shipwreck
-63, 44, -75 - water lake
-729, 38, -1493 lava pool
-105,-34,-177 - geode

they are all somewhat common right now. Might have to make them a bit rarer in the future but for now I think it's good when they're easy to find both so players actually do find them and they get some testing.

Perspective

End cities are going to be fairly easy with this as level 2 (multipart structures) - the plan is to make it so you put the structblock inside of another schematic (or just define its relative position) so it gets gradually placed by lbm and will always fit.

Level 3 is going to be nether fortresses and overworld (surface) structures which need to be more clever about terrain.

o wait i gotta figure out noise values instead of fill ratio - i noticed otherwise they get placed differently when a new structure is added rofl

well gotta tweak the noise values still ... sometimes theres way too many lava pools lol

I couldn't find any lava or water lakes at the listed coordinates.
Same seed with a completely reset 'minetest.conf'; so vanilla values for v7 mapgen.

But, I eventually found one of each here:
water lake: -63, 44, -75
lava lake: -729, 38, -1493

Shipwrecks, and geodes came up fine at the listed coordinates. Also, saw a lot of dungeons here, & there.

Looks good, nice work!

On the minor issue side of things.

That little wrapper around the "spawnstruct" chat command causes Minetest to label the mod it's under as "???"; when you type, 'help' in-game. Instead of the usual "mcl_structures".

So, it may eventually be better to just add the parameters for shipwrecks, & lakes to the command directly.
As right now. If you remove the wrapper; the commands to place shipwrecks/lakes still works, but they don't show up as optional parameters.

But, we can tweak this at another time if you want.

well one of the ideas of this is to not have to edit 50 places in the code if you want to add a structure (the whole mcl_mapgen_core / mcl_structures circus is quite ridiculous tbh ^^ )

It seems less than ideal if they need to be added to /spawnstruct ... but i have an idea. i suppose i could just rewrite its params field on_mods_loaded

yep looks like that works ... and yeah i changed the noise of surface pools and forgot to put in new coords

Side note about dungeons:

They were not touched here at all - there's always been tons of them.

Incidentally i discovered that they can make mapgen fairly slow. A number of times i thought I made it slow but then when i measured it tsm_railcorridors came up hehe.

I'll look at it some time and see if it can be made faster.
