5b338638e0 Mgv6 mudflow: Remove decoration if 'dirt with grass' below flows away (#5798)
Mudflow of a neighbouring mapchunk extends into a mapchunk's edge, and could
remove 'dirt with grass' from under a decoration, creating unsupported
decorations.

Remove any decoration above if a 'dirt with grass' node is removed by mudflow.

a901a56859 Dungeongen: Add and improve parameters
Add:
Bool for 'only_in_ground'.
Min and max corridor length.
Min and max room size with X, Y, Z components.
Min and max large room size with X, Y, Z components.

'only_in_ground = false' allows core mapgens to create structures
in air and water using dungeongen.
Corridor length parameters replace a fixed random range.
Room size parameters replace the former system where one parameter
'roomsize' was added to fixed random ranges.

All parameters are set for no change to current dungeon behaviour.

Remove some now-redundant and long-unused code.

047168ca83 Mgv6: Add fallback node for gravel
Gravel now falls back to stone.
Gravel is not a particularly fundamental node, allowing it to fall back
to stone frees up subgames from having to include a gravel node.
Non-blob-ore gravel is only present in mgv6 as extremely rare 'gravel
biomes'.

As with the other mapgens, now that wide stairs in dungeons are
possible we can now finally add stairs to desert stone dungeons.

ea12da939f Mapgen: Remove unused 'flat' and 'trees' flags from mg_flags
When the 'flat' and 'trees' flags were moved into mgv6_spflags they
were left in mg_flags in an attempt to support old mgv6 worlds. However
their appearence in mg_flags causes confusion, also, later, old-world
support was found to be broken for mgv6 worlds with 'notrees'.

This commit cleans up the mess and comes a month after a thread warning
of the change, and explaining the required action, was posted in the
news subforum. Only old mgv6 worlds with 'flat' or 'notrees' are
affected, a small minority of worlds, the required action being
correctly setting these flags in mgv6_spflags.

Disable a section of the 'map settings manager' unit test which is to
be changed as it is causing problems for pull requests.

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.

04fb10914c Dungeons: Generalise use, add capabilities, various modifications
- Generalise node names to c_wall and c_alt_wall
- Remove 'mossratio' and instead disable alt_wall loop if
  c_alt_wall == CONTENT_IGNORE
- Use one generalised 3D noise for alternative wall nodes and in
  mgv6 create moss distribution similar to the previous

- Rename rarity noise to density noise and enable the option of multiple
  dungeons per chunk determined by the value. Recreate previous distribution
- Add parameters for min and max rooms per dungeon
- Add dungeon y limits

- Integrate river water properly

Generalisation is needed now that we have sandstone and desert stone
dungeons by default and can choose any node for alternative structure.
The current code is based around cobble dungeons with mossycobble
alternative nodes, the 2 noises controlling the alternative nodes
are based on wetness.

Enabling multiple dungeons per chunk with definable number of rooms
allows the option of very dense and complex underground structures
that could interconnect to create megastructures.
Y limits are added to be consistent with other mapgen elements, and
enable locaton of dungeon or megastructure realms as part of our
'stacked realms' philosophy.

7233a1228e Lighting: Fix nearly all issues
The cause of a single light source seemingly being lit without spread
was due to its creation in the +Y mapblock boundary layer during map
generation, which was ignored as the overtop.  This overtop explicitly
needs to be omitted during sunlight propagation, however.  To accomplish
this, Mapgen::calcLighting() was split into separate functions taking
separate parameters.
Additionally, do not diminish light too early during spread.  This fixes the
output inconsistency between Map::updateLighting and Mapgen::calcLighting.
