859141a0ce Cavegen/Mgv5/Mgv7: Add optional giant caverns
Add to MapgenBasic for use by multiple mapgens.
Add to mgv5 and mgv7, enabled by default.

Similar to mgvalleys caverns but half the scale.
Parameters for upper y limit, distance caverns taper to full size, and
noise threshold (full cavern size).
As with mgvalleys caverns are generated first and classic caves are
disabled in any mapchunk containing a cavern, to avoid excessive
spreading volumes of liquids.
This also avoids floating blobs of liquid where a large classic cave
has overgenerated out into a neighbouring previously-generated mapchunk.

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.

92705306bf Mapgen: Refactor mapgen creation and management
- Move mapgen creation logic out of EmergeManager and into Mapgen
- Internally represent mapgen type as an enum value, instead of a string
- Remove the need for a MapgenFactory per mapgen

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.

87bc39dca7 Mapgen: Combine generateBiomes, dustTopNodes, and generateCaves
This commit condenses the above methods into a single implementation used by
V7, V5, Flat, Fractal, and Valleys mapgens and introduces MapgenBasic.

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.

4adbd69a37 FindSpawnPos: Let mapgens decide what spawn altitude is suitable
To avoid spawn search failing in new specialised mapgens
Increase spawn search range to 4000 nodes
Add getSpawnLevelAtPoint() functions to EmergeManager, class Mapgen
and all mapgens
Remove getGroundLevelAtPoint() functions from all mapgens except mgv6

ground level)
Make mgvalleys flag names consistent with other mapgens
Remove now unused 'vertical spawn range' setting
