paramat ec0c4d33db Map generation limit: Make per-world
The setting limits map generation but affects nothing else.
Add 'mapgen_limit' to global mapgen parameters.
Move 'blockpos_over_mapgen_limit()' to the only place it is called
from: map.cpp.
Allow teleportation to any part of the world even if over the set
mapgen limit.
Simplify the reading of this limit in mgvalleys.
Remove the 'map_generation_limit' setting.

paramat d3131aeae7 Map generation limit: Rewrite
The previous implementation applied the setting to blockpos_over_limit(),
objectpos_over_limit() and in createSector(), causing many bugs near the
world edge.

First revert the previous implementation.
Rename blockpos_over_limit() to blockpos_over_max_limit() for clarity.
Add a new function to mapblock.h called blockpos_over_mapgen_limit() that
checks against the map_generation_limit setting, and call this only from
the code that decides where mapgen stops.
Use MAX_MAP_GENERATION_LIMIT in objectpos_over_limit() to reduce the
chance of bugs, there is no need to use map_generation_limit here.

Loïc Blot f8ad01ab7c Update server min protocol version to v24 (#5411)
* Update server min protocol version to v24

It's based on @sfan5 stats. See https://kitsunemimi.pw/tmp/serverlist_stats_2017-03-17.txt

v24 was bumped 25/08/14 and 0.4.11 was released 25/12/14

* Drop protocol v23 and lesser code

Dániel Juhász ab371cc934 Light calculation: New bulk node lighting code
This commit introduces a new bulk node lighting algorithm to minimize
lighting bugs during l-system tree generation, schematic placement and
non-mapgen-object lua voxelmanip light calculation.

If the block above the changed area is not loaded, it gets loaded to avoid
lighting bugs.
Light is updated as soon as write_to_map is called on a voxel manipulator,
therefore update_map does nothing.

paramat 111e7e1cc8 Voxelmanip: Do not emerge or blit to blocks over map gen limit
Placing a structure that extends into mapblocks that extend past
map_gen_limit causes a crash. For example a sapling growing at the
world edge which adds leaves beyond the edge, or placing a structure
using the lua voxelmanip, or placing a schematic or l-system tree.

Do not run the 'load_if_inexistent' block of code if the mapblock
is over limit, this also marks the mapblock with the flag
VMANIP_BLOCK_DATA_INEXIST which later prevents blitting back those
mapblocks.

This fix therefore uses existing functionality by having the same
effect as the 'load_if_inexistent' bool being false.

paramat ddcf8422a2 Map generation limit: Fix checks for block/sector over-limit
Fix the maths that check if any part of a mapblock or sector is over the
set map_generation_limit.
Therefore avoid the loading of any over-limit blocks that were previously
generated when map_generation_limit was larger. The set limit can vary
for a world because it is not yet a per-world mapgen parameter, even when
it is sometimes it will be changed deliberately.
Therefore avoid a player being returned to world centre if they re-enter
a world while being over-limit.

Fix the createSector() crash caused by a mob spawning over-limit in an
over-limit mapblock

Dániel Juhász 3f8261830e Improve getPointedThing() (#4346)
* Improved getPointedThing()

The new algorithm checks every node exactly once.
Now the point and normal vector of the collision is also returned in the
PointedThing (currently they are not used outside of the function).
Now the CNodeDefManager keeps the union of all possible nodeboxes, so
the raycast won't miss any nodes. Also if there are only small
nodeboxes, getPointedThing() is exceptionally fast.
Also adds unit test for VoxelLineIterator.

* Cleanup, code move

This commit moves getPointedThing() and
Client::getSelectedActiveObject() to ClientEnvironment.
The map nodes now can decide which neighbors they are connecting to
(MapNode::getNeighbors()).

MillersMan 9714cdcf4b Liquids: Update flow on block load
When loading a block add liquid-nodes that might flow away or spread to
neighbours to the transforming_liquid queue.

MillersMan cc36f5e99a Liquids: Preserve flow state if 'ignore' is a neighbour
Prevent waterfalls from falling down or streams from flowing away when the
source node is in an unloaded block - Nodes near a CONTENT_IGNORE node will
be interpreted as if the ignored node is a liquid node that just supports
the current state of the nodes in question.

Dániel Juhász be39f61359 Use node lighting for liquid spreading

Dániel Juhász c071efaa43 Improved lighting
This commit rewrites the procedure that is responsible for light
updating.

this commit
-provides iterative solutions for unlighting and light spreading
-introduces a new priority queue-like container for the iteration
-creates per-node MapBlock caching to reduce retrieving MapBlocks from
the map
-calculates with map block positions and in-block relative node
coordinates
-skips light updating if it is not necessary since the node's new light
will be the same as its old light was

kwolekr 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.
