b55fc3d773 mapgen: drop mapgen id from child mapgens.
This id must be owned by the child mapgen and never be set to a misc value by a developer

Also use nullptr in some places

Biome API: Fix absent water decorations and dust, in deep water (#7470)
Previously, the biomemap was 'BIOME_NONE' for a mapchunk column if a
stone surface was not found in it, causing water surface decorations
and water surface dust to fail.

Store the biome ID of the biome calculated at a water surface and add
it to the biomemap if the biomemap is 'BIOME_NONE' for the mapchunk
column. The biome calculated at a stone surface still has priority
for the biomemap entry, as it should.

Edit an incorrect comment.

Biome dust: Revert fix that added dust to mod structures (#7464)
Revert commit 99143f494711034068685b6ee845ce19fa09d7d9 and commit
f4ca830abe1aa22875c99b31bf2ee56e26f83f05.

These commits caused biome dust to be applied even when there was no core
mapgen terrain in a mapchunk column. So the dust, which overgenerates,
then appeared on structures added by mods in 'on_generated', such as
floatlands, asteroids or above-surface realms.

Mapgen flags: Add 'biomes' global mapgen flag (#7355)
Previously the only way to disable biomes was to 'clear' the registered
biomes in a mod, but this method causes large amounts of unnecessary
processing:
1. Calculation of 4 2D noises.
2. Looping through all nodes of a mapchunk replacing nodes with identical
nodes.
The new flag disables those operations.

Biomemap: Avoid empty biomemap entry to fix failing biome dust (#7393)
'generateBiomes()' constructs the biomemap as it generates biomes.
The biome calculated at first stone surface encountered is added to
the biomemap.
Previously, if no stone surface was encountered in a mapchunk column
the biomemap was left empty for that (x, z) position, causing biome
dust and water surface decoration placement to fail.

If at the base of a mapchunk column the biomemap is empty, add the
currently active biome to the biomemap, or if biome is NULL calculate
it for this position and add it to the biomemap.

Mapgen caves: Re-order generation to fix cavern bug
Previously, caverns confused tunnel generation causing biome top and filler
nodes to appear in caverns.
Split 'generateCaves()' into 2 functions to separate tunnel and large
randomwalk cave generation.
In each mapgen re-order cave generation to generate tunnels before caverns.

Biome API / dungeons: Add biome-defined dungeon nodes
Add new biome fields 'node_dungeon', 'node_dungeon_alt', 'node_dungeon_stair'.
If 'node_dungeon' is not defined dungeons fall back to classic behaviour.

Remove messy and imprecise dungeon material code from 'generateBiomes()'.
Code deciding dungeon materials is now in 'generateDungeons()' and uses the
biome at mapchunk centre for more precision.

Remove hardcoded 'MG_STONE' types as long intended.

861cfd8484 Dungeons: Avoid generation in multiple liquid nodes and 'airlike'
Previously only 'mapgen water source' and 'mapgen river water source'
were checked for. Games can use multiple liquid nodes defined for biomes,
many of which will not be aliased to those 2 mapgen aliases, causing
floating dungeons to generate in some liquids.

Now we check for liquid drawtype instead, so can remove liquid nodes
from dungeonparams.

Also check for 'airlike' drawtype instead of 'CONTENT_AIR' to avoid
generation in 'airlike' nodes in some rare situations. This will also be
needed for when we add definable biome air nodes.

ec93893c7f Biome dust node: Only place on 'walkable' cubic non-liquid drawtypes
No longer decide placement on 'buildable_to' parameter.
Dust nodes only look acceptable placed on cubic nodes.
Modders may not want to make their plantlike decorations 'buildable_to'.
