fd32005b0f Caverns: Remove unnecessary liquid excavation
Also disable CavesRandomWalk at a safer distance from caverns.

Excavating liquids in cavern code is unnecessary as in practice we are already
successfully disabling the generation of liquid caves that could intersect
with caverns and cause excessive amounts of spreading liquids in caverns.

However to be safer this commit now disables liquid caves at a larger distance
from caverns, to compensate for liquid caves being able to generate up to a
mapblock beyond a mapchunk border.

Not excavating liquids in cavern code also allows a feature i am working on in
experimental new core mapgens, but also allows for more flexibility in future.

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.

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.
