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

Add API for mods to hook liquid transformation events (#11405)
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.

bf22184d6e Fix unnecessary exception use in 3 more methods (#8791)
* Fix unnecessary exception use in Server::SendBlocks

The code in this method calls getBlockNoCreate and then
messes around with try...catch to skip blocks which are not
in the memory. Additionally, it repeatedly calls
m_env.getMap() inside this loop. Speed the code up by
extracting the m_env.getMap() out of the loop and getting
rid of the try...catch.

* Fix unnecessary exception use in Server::SendBlock

Another unnecessary try...catch is slowing down
Server::SendBlock. Remove that to speed it up and get a nice
side effect of simplifying the code in question.

* Fix unnecessary exception use in MMVManip::initialEmerge

Remove another unneeded exception usage from
MMVManip::initialEmerge to speed that code up and simplify
it but be careful to not remove the braces as there is a
TimeTaker in use there.

The Map::getSectorNoGenerate throws an exception but no other

misuse in ClientMap::emergeSector and remove the exception
throwing version of the method along with the "NoEx" suffixes
in the names of these methods.

e9ceead81d Fix unnecessary exception use in Map::isNodeUnderground
The isNodeUnderground calls getBlockNoCreate which calls
getBlockNoCreateNoEx and throws InvalidPositionException
if the returned value is nullptr, which isNodeUnderground
then catches to return "false". Remove the try..catch in
isNodeUnderground by calling getBlockNoCreateNoEx instead
of getBlockNoCreate and checking the returned value for
nullptr.

eb2bda7d0b Optimize string (mis)handling (#8128)
* Optimize statbar drawing

The texture name of the statbar is a string passed by value.
That slows down the client and creates litter in the heap
as the content of the string is allocated there. Convert the
offending parameter to a const reference to avoid the
performance hit.

* Optimize texture cache

There is an unnecessary temporary created when the texture
path is being generated. This slows down the cache each time
a new texture is encountered and it needs to be loaded into
the cache. Additionally, the heap litter created by this
unnecessary temporary is particularly troublesome here as
the following code then piles another string (the resulting
full path of the texture) on top of it, followed by the
texture itself, which both are quite long term objects as
they are subsequently inserted into the cache where they can
remain for quite a while (especially if the texture turns
out to be a common one like dirt, grass or stone).

Use std::string.append to get rid of the temporary which
solves both issues (speed and heap fragmentation).

* Optimize animations in client

Each time an animated node is updated, an unnecessary copy of
the texture name is created, littering the heap with lots of
fragments. This can be specifically troublesome when looking
at oceans or large lava lakes as both of these nodes are
usually animated (the lava animation is pretty visible).
Convert the parameter of GenericCAO::updateTextures to a
const reference to get rid of the unnecessary copy.

There is a comment stating "std::string copy is mandatory as
mod can be a class member and there is a swap on those class
members ... do NOT pass by reference", reinforcing the
belief that the unnecessary copy is in fact necessary.
However one of the first things the code of the method does
is to assign the parameter to its class member, creating
another copy. By rearranging the code a little bit this
"another copy" can then be used by the subsequent code,
getting rid of the need to pass the parameter by value and
thus saving that copying effort.

* Optimize chat console history handling

The GUIChatConsole::replaceAndAddToHistory was getting the
line to work on by value which turns out to be unnecessary.
Get rid of that unnecessary copy by converting the parameter
to a const reference.

* Optimize gui texture setting

The code used to set the texture for GUI components was
getting the name of the texture by value, creating
unnecessary performance bottleneck for mods/games with
heavily textured GUIs. Get rid of the bottleneck by passing
the texture name as a const reference.

* Optimize sound playing code in GUIEngine

The GUIEngine's code receives the specification of the sound
to be played by value, which turns out to be most likely a
mistake as the underlying sound manager interface receives
the same thing by reference. Convert the offending parameter
to a const reference to get rid of the rather bulky copying
effort and the associated performance hit.

* Silence CLANG TIDY warnings for unit tests

Change "std::string" to "const std::string &" to avoid an
unnecessary local value copy, silencing the CLANG TIDY
process.

* Optimize formspec handling

The "formspec prepend" parameter was passed to the formspec
handling code by value, creating unnecessary copy of
std::string and slowing down the game if mods add things like
textured backgrounds for the player inventory and/or other
forms. Get rid of that performance bottleneck by converting
the parameter to a const reference.

* Optimize hotbar image handling

The code that sets the background images for the hotbar is
getting the name of the image by value, creating an
unnecessary std::string copying effort. Fix that by
converting the relevant parameters to const references.

* Optimize inventory deserialization

The inventory manager deserialization code gets the
serialized version of the inventory by value, slowing the
server and the client down when there are inventory updates.
This can get particularly troublesome with pipeworks which
adds nodes that can mess around with inventories
automatically or with mods that have mobs with inventories
that actively use them.

* Optimize texture scaling cache

There is an io::path parameter passed by value in the
procedure used to add images converted from textures,
leading to slowdown when the image is not yet created and
the conversion is thus needed. The performance hit is
quite significant as io::path is similar to std::string
so convert the parameter to a const reference to get rid of
it.

* Optimize translation file loader

Use "std::string::append" when calculating the final index
for the translation table to avoid unnecessary temporary
strings. This speeds the translation file loader up
significantly as std::string uses heap allocation which
tends to be rather slow. Additionally, the heap is no
longer being littered by these unnecessary string
temporaries, increasing performance of code that gets
executed after the translation file loader finishes.

* Optimize server map saving

When the directory structure for the world data is created
during server map saving, an unnecessary value passing of
the directory name slows things down. Remove that overhead
by converting the offending parameter to a const reference.
