* TileLayer: use shared_ptr for vector framespec
This reduce memory copy of TileLayer from (4 to 16) * FrameSpec where FrameSpec = (sizeof(int) + 3 * sizeof(ptr)) to int + sizeof(ptr)
Callgrind difference

* Fix one push_back to use vector::emplace_back & optimize inclusions
* VoxelManip cleanups (const ref, const move) permitting to improve a little bit performance
* VoxelArea: precalculate extent (performance enhancement)
This permits to reduce extend high cost to zero and drop many v3s16 object creation/removal to calculate extent
It rebalance the client thread update to updateFastFaceRow instead of MapBlockMesh generation
This will also benefits to mapgen
Allows setting of the mountain 'zero level' (y where density gradient is zero).
It is easy to vertically shift smooth terrain by editing noise parameter 'offset',
but vertically shifting mountain terrain was complex and imprecise, involving
making a calculation based on an average of the mountain height parameter.
Ensure in-cloud fog is always stronger than outside-of-cloud-fog even when
using a small view range.
Also limit in-cloud fog range to a maximum of 32 nodes to keep it fairly
strong when using a large view range.
The change from 800x600 to 1024x576 (16:9) was a reduction in height which caused
user interface to become smaller.
Continue to use width 1024 as it is a common small screen width.
* [CSM] Add flavour limits controlled by server
Server send flavour limits to client permitting to disable or limit some Lua calls
* Add limits for reading nodedefs and itemdefs
* flavour: Add lookup node limits
* Merge get_node_or_nil into get_node.
Sending fake node doesn't make sense in CSM, just return nil if node is not available for any reason
* Add node range customization when noderange flavour is enabled (default 8 nodes)
* Limit nodes range & disable chat message sending by default
* Bump protocol version
Spawn player 1 node higher to avoid spawning waist-deep in a possible
biome 'dust' node, such as tundra snowblock.
Tune default offset to spawn players in a more interesting location on the
mandelbrot sets, on a raised area that looks like a spawn platform.
Tune julia parameters to help avoid spawn search failing, especially for
fractal 6.
For consistency return to 'FPS =', add comma before FPS.
Remove 'R' from 'range_all' as may be re-keymapped.
Remove inconsistent brackets from 'range_all'.
Change 'v_range' to 'view_range'.
Add 'pos = ' before co-ordinates.
Add spaces around '=' in yaw display.
Remove brackets from around 'yaw' and 'seed'.
Move 'pointing_at' to 3rd line.
Remove 'param1' (0 for all solid nodes and unreadable for light sources due to
light bank encoding).
Remove file name of pointed node top tile (this also removes the need to get
ContentFeatures for the node, slightly improving performance).
Replace quotes around node data with brackets, looks better and more consistent.
Add 'guitext3' for third line.
Use 'setVisible' for all 3 lines to control the setting of each text rectangle.
Improve logic of 3rd line to only run code it needs to depending on whether
pointing data is avaialble and whether node is not 'ignore' and not 'unknown'.
* New TOCLIENT_CHAT_MESSAGE packet
* Rename old packet to TOCLIENT_CHAT_MESSAGE_OLD for compat
* Handle TOCLIENT_CHAT_MESSAGE new structure client side
* Client chat queue should use a specific object
* SendChatMessage: use the right packet depending on protocol version (not complete yet)
* Add chatmessage(type) objects and handle them client side (partially)
* Use ChatMessage instead of std::wstring server side
* Update with timestamp support
Fix taking damage caused by sneaking over a nodebox gap.
Fix strange behaviour on stair nodeboxes.
Enable jumping from node edges while sneaking.
Enable movement around corners while sneaking on a 1-node-high groove in a wall.
Add 'biome_zero_level' argument to 'generateBiomes()', 'deco_zero_level'
argument to 'placeAllDecos()' and 'ore_zero_level' to 'placeAllOres()'
to allow mapgens to vertically shift the registered biomes, decorations
and ores per-mapchunk.
Will also allow many realm possibilities in future mapgens.
Useful for underwater plants.
Node consists of a base cube plus a plantlike extension that can pass through
liquid nodes above without creating air bubbles or interfering with liquid flow.
Uses paramtype2 'leveled', param2 defines height of plantlike extension.
This commit introduces Raycast, a Lua user object, which can be
used to perform a raycast on the map. The ray is continuable, so one can
also get hidden nodes (for example to see trough glass).
Fixes issue #3576
* Clouds now take camera position as 3D, not 2D
* Cloud grid filling extracted to gridFilled method
* Clouds detect whether camera is inside cloud
* Camera in cloud changes fog by overriding sky colors
with cloud color
* Sun, moon and stars can be temporarily disabled
with setBodiesVisible
* Disabling fog also disables all "inside cloud" behaviors
Allow `core.copy_dir` (main menu API) to copy directories from a
non-Minetest location. The check to disallow copying to non-Minetest
locations is retained.
* Irrlicht cleanup: cleanup various object to use RenderingEngine
* CAO doesn't need scenemanager in addToScene
* Camera doesn't need VideoDriver pointer or SceneManager in constructor
* Hud doesn't need driver & scene manager in constructor
* Hud doesn't need scenemanager pointer
* Tile.h doesn't need IrrlichtDevice header (just SMaterial)
* WieldMeshSceneNode: only take scene, we always use scene root node as parent
* Load client-side mods into memory before executing them.
This removes the remaining filesystem access that client-sided mods had and it will hopefully make then more secure.
* Lua Virtual filesystem: don't load the files into memory just scan the filenames into memory.
* Fix the issues with backtrace
* fix most of the issues
* fix code style.
* add a comment
Commit cad10ce3b747b721fd63784915e05f12bc488128 altered the parameter
'float_mount_height' but was missing the necessary line in the constructor
to get the altered value from 'params'.
Fixes 3D floatland terrain generating everywhere.
