This could happen before and would just silently discard the data,
but now that Lua can create VManips without loading from map beforehand
we definitely need to handle this case.
* Detect air-only blocks instead day/night differences
* Write !is_air into the former day-night-diff bit on disk, so that old server can still read maps written by new servers
* Only set is_air bit when reading from disk
Reduce the number of drawcalls by generating a mesh per 8 blocks (2x2x2). Only blocks with even coordinates (lowest bit set to 0) will get a mesh.
Note: This also removes the old 'loops' algorithm for building the draw list, because it produces visual artifacts and cannot be made compatible with the approach of having a mesh for every 8th block without hurting performance.

* refactoring(StaticObjectList): don't expose m_active and m_stored anymore
This prevents our old crap code where anyone can access to StaticObjectList. use proper modifiers. It also permits to do a short cleanup on MapBlock using a helper
* refactoring(MapBlock): reduce a bit exposed m_active_blocks variable
* refactoring: MapBlock::m_node_timers is now private
We already had various helpers to perform this privatization, just use it. Also factorize the MapBlock stepping code for timers using already existing code and importing them from ServerEnvironment to MapBlock.
It's currently done pretty straight forward without any inheritance as MapBlock is just used everywhere, maybe in a future we'll have ServerMapBlock over MapBlock. Currently for a simple function let's just use proper objects and add a comment warning
* refactoring(Server): fix duplicated function for add/remove node
* refactoring(guiFormSpecMenu): add removeAll function to prevent duplicated code
* refactoring(ShadowRenderer) + perf: code quality + increase performance
* All callers are already using the point and we should never test a function with nullptr node, it's a bug. Removed workaround which was hacky and fix the bug
* Drop clientmap lookup from shadowrendered, just use directly its
pointer and forbid to push it in the generic list
* Reduce memory pressure on the renderShadowObject by preventing
deallocating and reallocating multiple vectors on each node
* refactoring(MapBlock): reduce exposure of MapBlock::m_static_objects
It's not complete as some parts of the code are pretty nested, but it's better than before :)
* fix: better working on new functions & drop unwanted 2 lines

Add API for mods to hook liquid transformation events
Without this API, there is no reliable way for mods to be
notified when liquid transform modifies nodes and mods are
forced to poll for changes. This allows mods to detect
changes to flowing liquid nodes and liquid renewal using
event-driven logic.
Remove old defaults system
Introduce priority-based fallback list
Use new functions for map_meta special functions
Change groups to use end tags
Unittest changes:
* Adapt unittest to the new code
* Compare Settings objects
Run unused functions reported by cppcheck
This change removes a few (but not all) unused functions.
Some unused helper functions were not removed due to their complexity and potential of future use.
