6c9f10e132 Mgv7 floatlands: Various improvements
Floatland base terrain underside was too thin, causing excessive water
leakage through tunnels under lakes, now make it thicker.
Floatland mountain terrain had a rim 1 node thick which made it bare
stone, now make it 2 nodes thick to merge with the floatland base
terrain rim and to have a layer of biome material.
Make mountain terrain more exponentially shaped by altering the
exponent.
Remove unnecessary and potentially ugly MYMAX() applied to
n_base_height.

56ea77ea96 Mgv7: Avoid mid-air spawn on disabled mountain terrain, optimise function
'getSpawnLevelAtPoint()' did not account for disabled mountains, it
was possible to be spawned in mid-air where a mountain surface would
have been.

Avoid check for river area if rivers are disabled.

3c63c3044d Add MapSettingsManager and new mapgen setting script API functions
This commit refactors the majority of the Mapgen settings system.
- MapgenParams is now owned by MapSettingsManager, itself a part of ServerMap,
  instead of the EmergeManager.
- New Script API functions added:
    core.get_mapgen_setting
    core.get_mapgen_setting_noiseparams,
    core.set_mapgen_setting, and
    core.set_mapgen_setting_noiseparams.
- minetest.get/set_mapgen_params are deprecated by the above new functions.
- It is now possible to view and modify any arbitrary mapgen setting from a mod,
  rather than the base MapgenParams structure.
- MapgenSpecificParams has been removed.

9997e2030c Mgflat/fractal/v7/valleys: Denser 3D noise tunnels
Reduce spread from 96 to primes 61 and 67 (either side of 64)
Prime spreads help to keep 3D noise periodic features unaligned
'cave width' 0.2 to preserve tunnel width
Reduce octaves to 3 to improve network structure

569998011e Mgv7: Always carve river channels in mountain terrain
Previously, rivers were sometimes blocked by vertical walls

0df5c01a8c Mapgen: Remove calculateNoise from most mapgens
This commit moves noise calculation to the functions where the noise is
actually required, increasing the separation of concerns and level of
interdependency for each mapgen method.  Valleys Mapgen is left unmodified.

76f4856479 Move biome calculation to BiomeGen
BiomeGen defines an interface that, given a set of BiomeParams, computes biomes
for a given area using the algorithm implemented by that specific BiomeGen.
This abstracts away the old system where each mapgen supplied the noises
required for biome generation.

fed5dd3b5d Mgv7: Combine mountain terrain generation with base terrain generation
Previous mountain terrain generation was by necessity placing
stone in air, this was removing air from any overgenerated
structures such as tunnels, dungeons and large caves
Moving it into the base terrain generation loop ensures that
only 'ignore' is replaced

generateRidgeTerrain: only return if node_max.Y < water_level - 16
Previously, if water level was set a few nodes above a mapchunk
border the river channel was only partially excavated

bb2ee54d3b Mapgen: Fix light in tunnels at mapchunk borders
