8b73743baa Reduce number of recursively included headers
This should improve compilation speed.

Things changed:
* Prefer forward-declarations in headers.
* Move header-includes out of headers if possible.
* Move some functions definitions out of headers.
* Put some member variables into unique_ptrs (see Client).

Reduce exposure of various internals (#12885)
* 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

04cc9de8f2 MeshUpdateQueue: Add a MapBlock cache that minimizes the amount of MapBlock copying done in the main thread
Cache size is configurable by the meshgen_block_cache_size (default 20 MB).

New profiler stats:
- MeshUpdateQueue MapBlock cache hit %
- MeshUpdateQueue MapBlock cache size kB

Removes one type of stutter that was seen on the client when received MapBlocks
were being handled. (the "MeshMakeData::fill" stutter)

Kind of related to at least #5239

Originally preceded by these commits, now includes them:
- Move the mesh generator thread into src/mesh_generator_thread.{cpp,h}
- mesh_generator_thread.cpp: Update code style
- MeshUpdateThread: Modify interface to house a different implementation: Actual functionality will be changed by next commits.
- MeshMakeData: Add fillBlockData() interface (so that caller can fill in stuff from eg. a MapBlock cache)

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.

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.

3955f51253 Objectpos over limit: Avoid crash caused by sector over limit
Reduce the object limit by mapblock size, to avoid objects being
added just inside the map generation limit but in a block and sector
that extend beyond the map generation limit.

Change notification of 'objectpos over limit' from red in-chat ERROR
to in-terminal only WARNING, since this will happen often using mob
mods near the world's edge.

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

f61f817b9c Disallow placing entities outside safe boundaries
Entity positions are serialized as F1000. Disallow placing
entities outside safe borders with the minetest.add_entity
call.

Note that this patch only enforces those boundaries for
placing entities, moving entities that move outside boundaries
aren't affected.

Thanks to @nanepiwo for pointing this out.

283bf97a1c Serialisation: documentation fixes, clarifying renames and whitespace fixes
1. Do two renames:
	* SER_FMT_CLIENT_VER_LOWEST -> SER_FMT_VER_LOWEST_WRITE
	* SER_FMT_VER_LOWEST -> SER_FMT_VER_LOWEST_READ
Now the two define values are consistently named with the _WRITE defines
SER_FMT_VER_{HIGHEST,LOWEST}_WRITE, and to better point out what the two
serialisation versions actually are for.

2. wrap some lines in doc/worldformat.txt, and point out that the node
timers are serialized at a later point, as this can cause confusion about
what now happens (if one doesn't strictly read the if block's conditions).

3. some whitespace fixes in NodeTimerList::serialize, and one new comment.

80a7408e4d Fix a crash (assert) when client set serial version < 24 in INIT
When SER_FMT_VER_LOWEST is set to zero, then the test is stupid in INIT because all client works. In mapblock we check if client's serialization version is < 24, but if client sent serialization version < 24 (15 for example) the server set it and tried to send nodes, then BOOM

To resolve the problem:
* Create a different CLIENT_MIN_VERSION to handle this problem
* Remove the exception
* Use an assert in case of bad developer code
