Move Mapgen V7 river generation into the main generation loop (#10639)
All terrain generation now occurs in one loop, instead of rivers being
carved afterwards in a separate loop.
Fixes the removal of nodes added by mods in 'register on generated'.
Avoids other problems and reduces the chance of future bugs.
Mapchunk generation time is reduced.

Also fixes a code mistake which resulted in river channel generation
being disabled at floatland altitudes even when floatlands were disabled.

Add new Mapgen V7 floatland implementation (#9296)
Floatland structure is vertically-compressed 3D noise.
Uses a lacunarity of 1.618 (the golden ratio) for high quality
noise.
Floatlands appear between user-settable Y limits, with smooth
tapering at each limit.
Simple user-settable density adjustment.
Shadow propagation is disabled in and just below floatlands, no
shadows are cast on the world surface.
Can be reconfigured to create a solid upper world layer between
the Y limits, lakes/seas can be optionally added to this.

5146086a64 Drop content_sao.{cpp,h}
Move LuaEntitySAO to a new dedicated file
Drop TestSAO (useless object)
Drop the old static startup initialized SAO factory, which was pretty useless.
This factory was using a std::map for 2 elements, now just use a simple condition owned by ServerEnvironment, which will be lightweight, that will also drop a one time useful test on each LuaEntitySAO creation. This should reduce server load on massive SAO creation

Settings: Add get_flags API for mapgen flags (mg_flags, mgv6_spflags, ...) (#9284)
Unified flags handling in C++ and Lua Settings API
     -> Reading only, for now. Writing can be implemented later, if needed.
API function to read the currently active flags
     -> was impossible from Lua

Randomwalk cave liquids: Remove deprecated 'lava depth' parameter (#9105)
Low-disruption first step towards removing the hardcoded cave liquid
code. Since MT 5.0.0 cave liquids can be defined and located by
biome definitions instead.
In games that do not yet use biome definitions to define and locate
cave liquids (MTGame does), lava will now appear below
y = water_level - 256 instead of below 'lava depth' (usually y = -256).
Therefore no change in most mapgens if using the default 'lava depth'.

Randomwalk caves: Add parameters for number, proportion flooded. Allow small caves (#8928)
Add mapgen parameters to set the range of the random number of
randomwalk caves per mapchunk, and to set the proportion that are
flooded with liquids.
Default values are, for now, unchanged from the previous hardcoded
values.

Add parameters to allow small randomwalk caves
Disabled by default for now as they have never been present in the
non-mgv6 mapgens.

Dungeons: Settable density noise, move number calculation to mapgens (#8473)
Add user-settable noise parameters for dungeon density to each mapgen,
except V6 which hardcodes this noise parameter.

Move the calculation of number of dungeons generated in a mapchunk out
of dungeongen.cpp and into mapgen code, to allow mapgens to generate
any desired number of dungeons in a mapchunk, instead of being forced
to have number of dungeons determined by a density noise.

This is more flexible and allows mapgens to use dungeon generation to
create custom structures, such as occasional mega-dungeons.

Change mapgen order to ores > dungeons > decorations (#7656)
Previously dungeons > decorations > ores.
Decorations depend on the node they are placed on, and ore types are
increasingly able to place large continuous volumes of nodes, such as
strata. Decorations are increasingly being used underground.

The new order avoids a node being changed by ore generation after a
decoration has been placed on it.
The new order also avoids ores appearing in the walls of a dungeon if
the wall nodes match the local stone node.

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.

Mgv7: Avoid rivergen removing mod-placed nodes when overgenerating (#7388)
Only allow river generation to replace c_stone.
This also acts as an optimisation by being placed before canyon shape

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.

* Fix many issues reported by clang-tidy

We have many issues in code related to some performance to float <-> double.
Clang-tidy reported it in performance-type-promotion-in-math-fn

I fixed many of them. It's not ready for a promote to blocking

Also fix some value which should be const-ref
