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.

a5e4273575 Fix >5 year old PlayerSAO deletion bug
force_delete=true is usually set at shutdown in order to
also remove PlayerSAOs, however when too many objects
per block are detected force_delete is also set to true.
This was intended only for the current loop iteration but
obviously persisted to the next iterations thereby
deleting all other remaining SAOs.

eb49009d02 FreeType: address font license issues (#5230)
It appears we were shipping font files without license text, and I
had my doubts about the bitmap fonts being usable directly.

This replaces existing TTF fonts with Apache-2.0 licensed fonts from
chome core (Cousine, Arimo, Tinos). Include the full license file
for all three fonts.

The Lucida Sans font bitmap is removed entirely for non-freetype
builds. There is therefore only mono fonts for non-freetype builds.

984e063374 Footsteps: Fix offset footstep and shallow water sound bugs
Fix footstep sounds coming from nodes to either side when walking on a
1 node wide row of nodebox slabs such as default:snow.
Fix sand footsteps when swimming in 1 node deep water.

Use a new function 'getFootstepNodePos()' instead of 'getStandingNodePos()'
to avoid using a horizontally-offset 'sneak node' for sounds.

Sound is selected from the node BS * 0.05 below the player's feet, so
that 1/16th slabs will play the slab sound but 1/32nd slabs will not.
If the player is not 'touching ground' the node detection position is
changed to BS * 0.5 below to preserve footstep sounds when landing after
a jump or fall.

1de08e1961 Plantlike: Fix visual_scale being applied squared
This re-applies 2 commits that were reverted.

Visual_scale was applied twice to plantlike by accident sometime between
2011 and 2013, squaring the requested scale value. Visual_scale is
correctly applied once in it's other uses in signlike and torchlike.

Two lines of code are removed, they also had no effect for the vast
majority of nodes with the default visual_scale of 1.0.
The texture continues to have it's base at ground level.

Send sqrt(visual_scale) to old clients.

Keep compatibility with protocol < 30 clients now that visual_scale
is no longer applied twice to plantlike drawtype and mods are being
updated to a new value.

5707b739f3 Change default nodetimer_interval to 0.2s. (#5193)
We want to reduce the chance that we get lots and lots of node
timers all happening once a second, because we're better off doing
small bits of work as they are available.

Reducing this to 0.2 seconds will greatly reduce the total amount
of nodetimers that elapse at the same instance, while not effecting
total work load. This results in a far better chance of the server
keeping up with work loads.

a5ee7139a5 OpenAL sound: Use a simpler distance model
In createPlayingSoundAt(), AL_ROLLOFF_FACTOR is not set, so it has
the default value of 1.0, this makes the equation of the currently
used AL_EXPONENT_DISTANCE distance model identical to the equation
of the simpler AL_INVERSE_DISTANCE distance model.

Using AL_INVERSE_DISTANCE means an exponent is not processed,
exponents are quite intensive to process.
There is no change in sound attenuation behaviour.

The commented-out AL_ROLLOFF_FACTOR value is removed as it would
now have a different effect if used.

3e30731c1a Prevent SIGFPE on entity tile loading issue. (#5178)
While experimenting with entities I ran into this unresolvable
error where the server is sending some texture that the client
crashes on. The crash prevents the client from ever reconnecting,
resulting in a server that has to use clearobjects.

We shouldn't crash but just ignore the object and move on.

```

    baseimg=@0x7fffffffbe98: 0x9f1b010) at /home/sofar/git/minetest/src/client/tile.cpp:1744

```

After reconnecting, the client now can connect without issues
and displays an error message:

```

d873545ac7 Fix anticheat resetting client position after the client is teleported
Previously, m_move_pool could accomodate the client moving from the new
position to the old one, and the server accepted the client to go back
to its old position. However, it couldn't then accomodate the client
moving from its old to its new position, and therefore would reset position
to the old position. Thus, by emptying m_move_pool after a teleport, the
server no longer accepts the client to go back to its old position. A
drawback is however that a laggy client *will* trigger a few
"moved_too_fast" anticheats before being told about its new position.

Don't report player cheated if caused by lag.

c93f7f5cea Fix synchronization issue at thread start
If a newly spawned thread called getThreadId or getThreadHandle before
the spawning thread finished saving the thread handle, then the
handle/id would be used uninitialized.  This would cause the threading
tests to fail since isCurrentThread would return false, and if Minetest
is built with C++11 support the std::thread object pointer would be
dereferenced while ininitialized, causing a segmentation fault.

This fixes the issue by using a mutex to force the spawned thread to
wait for the spawning thread to finish initializing the thread object.

An alternative way to handle this would be to also set the thread
handle/id in the started thread but this wouldn't work for C++11
builds because there's no way to get the partially constructed object.

8e7449e092 Environment & IGameDef code refactoring (#4985)
* Environment code refactoring
* Cleanup includes & class declarations in client & server environment to improve build speed
* ServerEnvironment::m_gamedef is now a pointer to Server instead of IGameDef, permitting to cleanup many casts.
* Cleanup IGameDef
  * Move ITextureSource* IGameDef::getTextureSource() to Client only.
  * Also move ITextureSource *IGameDef::tsrc() helper
  * drop getShaderSource, getSceneManager, getSoundManager & getCamera abstract call
  * drop unused emerge() call
  * cleanup server unused functions (mentionned before)
* Drop one unused parameter from ContentFeatures::updateTextures
* move checkLocalPrivilege to Client
* Remove some unnecessary casts
* create_formspec_menu: remove IWritableTextureSource pointer, as client already knows it
* Fix some comments
* Change required IGameDef to Server/Client pointers
* Previous change that game.cpp sometimes calls functions with Client + InventoryManager + IGameDef in same functions but it's the same objects
* Remove duplicate Client pointer in GUIFormSpecMenu::GUIFormSpecMenu
* drop ClientMap::sectorWasDrawn which is unused

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

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()).
