It's likely that these could be used trick mods into revealing the insecure
environment even if they do everything right (which is already hard enough).
This ensures that no overflows (side-effects) happen within the find_nodes_in_area function by limiting coordinates like done in the map generation code.
This commit deprecates the forward, backward, left, and right binary
inputs currently used for player movement in the PlayerControl struct.
In their place, it adds the movement_speed and movement_direction
values, which represents the player movement is a polar coordinate
system.
movement_speed is a scalar from 0.0 to 1.0. movement_direction is
an angle from 0 to +-Pi:
FWD
0
_
LFT / \ RGT
-Pi/2 | | +Pi/2
\_/
+-Pi
BCK
Boolean movement bits will still be set for server telegrams and
Lua script invocations to provide full backward compatibility.
When generating these values from an analog input, a direction is
considered active when it is 22.5 degrees away from either
orthogonal axis.

Some games provide users with enough freedom to create items
with metadata longer than 64KB, preventing this from causing
issues is on them but we'll still do the minimum not to abort
the server if this happens.

Add ColorSpec to RGBA converter

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.
Fixes list clearing for inv:set_list() using same size, since 2db6b07.
addList() now clears the list in all cases. Use setSize() to resize without clearing.
* No more access to the singleton instance from everywhere (RenderingEngine::get_instance dropped)
* RenderingEngine::get_timer_time is now non static
* RenderingEngine::draw_menu_scene is now non static
* RenderingEngine::draw_scene is now non static
* RenderingEngine::{initialize,finalize} are now non static
* RenderingEngine::run is now non static
* RenderingEngine::getWindowSize now have a static helper. It was mandatory to hide the global get_instance access
Make the RenderingEngine filesystem member non accessible from everywhere
This permits also to determine that some lua code has directly a logic to extract zip file. Move this logic inside client, it's not the lua stack role to perform a such complex operation
Found also another irrlicht <1.8 compat code to remove
This fixes an out-of-bounds index access when the node resolver was already applied to the schematic (i.e. biome decoration).
Also improves the handling of the two cases: prior node resolving (m_nodenames), and after node resolving (manual lookup)
The only valid usecase for these is interfacing with OS APIs
that want a locale/OS-specific multibyte encoding.
But they weren't used for that anywhere, instead UTF-8 is pretty
much assumed when it comes to that.
Since these are only a potential source of bugs and do not fulfil
their purpose at all, drop them entirely.
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
Add more detailed light detection functions, a function to get the artificial light (torches) and a function to get the sunlight as seen by the player (you can specify timeofday).

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.
Features:
* Define Minimap available modes (surface/radar, scale) from Lua, using player:set_minimap_modes()
* New HUD elements for displaying minimap with custom size and placing
* New minimap mode for displaying a texture instead of the map
Fixes some other third person camera specific attachments.
Implements a single new flag for entities to be forced visible in first person mode.
Old mods do not need to be updated to use the new flag and are fully backwards compatible.
Blacklisted characters are replaced by '_' in the path. The display name is stored in world.mt, and duplicate file names are resolved by adding an incrementing suffix (_1, _2, _3, etc).
Incorrect parameter types are logged as errors, taking coercion into account.
This is a workaround to ensure mod compatibility.
Duplicate warnings are ignored per server instance.
Replace on_auth_fail callback with more versatile on_authplayer
Better clarify account login process in Lua API documentation
Change initial timestamp for newly registered accounts to -1
This adds support for optional “off state” icons for statbars. “off state icons” can be used to denote the lack of something, like missing hearts or bubbles.
Add "off state" textures to the builtin statbars.

* Server::overrideDayNightRatio doesn't require to return bool
There is no sense to sending null player, the caller should send a valid object
* Server::init: make private & cleanup
This function is always called before start() and loads some variables which can be loaded in constructor directly.
Make it private and call it directly in start
* Split Server inventory responsibility to a dedicated object
This splits permit to found various historical issues:
* duplicate lookups on player connection
* sending inventory to non related player when a player connects
* non friendly lookups on detached inventories ownership
This reduce the detached inventory complexity and also increased the
lookup performance in a quite interesting way for servers with thousands
of inventories.
* Fix configuration caching in log_deprecated
The configured variable was never set to true.
I've set the variables to thread_local because the configuration should be reloaded after reentering the world from mainmenu.
* Optimize getObjectsInsideRadius calls
our previous implementation calls the ActiveObjectMgr to return ids and then lookup those ids in the same map and test each object
Instead now we call the global map to return the pointers directly and we ask filtering when building the list using lamba.
This drop double looping over ranges of active objects (and then filtered one) and drop x lookups on the map regarding the first call results
ServerEnvironment is a huge class with many accessors. In various places it's not needed
Remove it to reduce the ServerEnvironment view.
Idea here is to reduce size of some of our objects to transport lightweight managers and permit easier testing
Pathfinder is now tied to a generic map, not a ServerMap, it can be
ported to client
Move LuaEntitySAO to a new dedicated file
Drop TestSAO (useless object)
Drop the old static startup initialized SAO factory, which was pretty useless.
This factory was using a std::map for 2 elements, now just use a simple condition owned by ServerEnvironment, which will be lightweight, that will also drop a one time useful test on each LuaEntitySAO creation. This should reduce server load on massive SAO creation
- Move the text segment below the 47-bit limit, needed for script_exception_wrapper which must be lightuserdata
- Replace CUSTOM_RIDX_SCRIPTAPI with full userdata
* Fix pathfinder fail when startpos is over air
* Note down pathfinder restrictions
* Implement real A* search
* Pathfinder: Implement buildPath non-recursively
* Update find_path documentation
* Pathfinder: Check if jump path is unobstructed
* Pathfinder: Fix drop check first checking upwards
* Pathfinder: Return nil if source or dest are solid
* Pathfinder: Use priority queue for open list
This bug is only exposed by 91eef646a59575bd9ae792e257bb6ad12fafc0b1
independent of the move of get_connected_players from Lua to C++.
Previously, there would be a small time window where the SAO had
its peer ID set to PEER_ID_INEXISTENT but the RemotePlayer was
still linked to the SAO, resulting in an ObjectRef that crashed
on certain function calls (#9387).
Unified flags handling in C++ and Lua Settings API
