This PR is the second attempt to translate builtin.
Server-sent translation files can be added to `builtin/locale/`, whereas client-side translations depend on gettext.
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.

This commit clarifies the maximal length of the serialized strings.
It will avoid accidental use of serializeString() when a larger string can be expected.
Removes unused Wide String serialization functions
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).
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.
* Drop genericobject.{cpp,h}
This file is not for generic object but for ActiveObject message passing.
Put ownership of the various commands to the right objects and cleanup the related code.
* Protect ServerActiveObject::m_messages_out
* typo fix
Does not clear the parent's attachment information when the child is deleted locally.
Either it was removed permanently, or just temporary - we don't know, but it's up to the server to send a *detach from child" packet for the parent.
This change reduces the amount of sent data towards clients. Inventory lists that are already known to the player are skipped, saving quite some data over time.
Raises protocol version to 38 to ensure correct backwards-compatible code.
* 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.

Avoid an unsuitable spawn position (which if outside mapgen limits can
cause a crash) if the main 0-3999 loop reaches its end. Fallback to a
spawn at 0,0,0.
Check the mapgen-returned 'spawn_level' value for being outside limits.
When 'air_count' reaches 2, move back down 1 to spawn in the lower
empty node.
If the spawn position is disallowed by 'objectpos_over_limit()', 'break'
from loop instead of 'continue' because positions above are probably
also over limit.
Reset 'air_count' to 0 if an obstruction is found, to make 'air_count'
consecutive empty nodes.
Allow spawn in 'airlike' drawtype nodes such as mod-added vacuum,
alien atmospheres, fog etc.
Add clarifying comments and improve codestyle.

* 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.
* Force send a mapblock to a player.
Send a single mapblock to a specific remote player.
This is badly needed for mods and games where players are teleported
into terrain which may be not generated, loaded, or modified
significantly since the last player visit.
In all these cases, the player currently ends up in void, air, or
inside blocks which not only looks bad, but has the effect that the
player might end up falling and then the server needs to correct for
the player position again later, which is a hack.
The best solution is to send at least the single mapblock that the
player will be teleported to. I've tested this with ITB which does this
all the time, and I can see it functioning as expected (it even shows
a half loaded entry hallway, as the further blocks aren't loaded yet).
The parameter is a blockpos (table of x, y, z), not a regular pos.
The function may return false if the call failed. This is most likely
due to the target position not being generated or emerged yet, or
another internal failure, such as the player not being initialized.
* Always send mapblock on teleport or respawn.
This avoids the need for mods to send a mapblock on teleport or
respawn, since any call to `player:set_pos()` will pass this code.
If a formspec is submitted from a form fields handling
callback of another form (or "formspec shown from another
formspec"), the fields submitted for it can get
rejected by the form exploit mitigation subsystem with a
message like "'zorman2000' submitted formspec
('formspec_error:form2') but server hasn't sent formspec to
client, possible exploitation attempt" being sent to logs.
This was already reported as #7374 and a change was made
that fixed the simple testcase included with that bug
report but the bug still kept lurking around and popping
out in more complicated scenarios like the advtrains TSS
route programming UI.
Deep investigation of the problem revealed that this
sequence of events is entirely possible and leads to the
bug:
1. Server: show form1
2. Client *shows form1*
3. Client: submits form1
4. Server: show form2
5. Client: says form1 closed
6. Client *shows form2*
7. Client: submits form2
What happens inside the code is that when the server in
step 4 sends form2, the registry of opened forms is
updated to reflect the fact that form2 is now the valid
form for the client to submit. Then when in step 5 client
says "form1 was closed", the exploit mitigation subsystem
code deletes the registry entry for the client without
bothering to check whether the form client says was
closed just now is indeed the form that is recorded in
that entry as the valid form. Then later, in step 7 the
client tries to submit its valid form fields, these will
be rejected because the entry is missing.
It turns out the procedure where the broken code resides
already gets the form name so a simple "if" around the
offending piece of code fixes the whole thing. And
advtrains TSS agrees with that.

* Optimize Server::SendCloudParams: use CloudParams object ref instead of deserialized attributes
This doesn't check the fields in anyway whatsoever so it should only be seen as a way to mitigate exploits, a last line of defense to make it harder to exploit bugs in mods, not as a reason to not do all the usually checks.

thread_local permits to limit variable lifetime to thread duration. Use it on each setting place which uses static to cache variable result only for thread lifetime. This permits to keep the same performance level & reconfigure server from MT gui in those various variables places.
Add thread_local to undersampling calculation too.
Previously, findSpawnPos() did not take the 'mapgen_limit' setting into account,
a small limit often resulted in a spawn out in the void.
Use the recently added 'calcMapgenEdges()' to get max spawn range through a new
mapgenParams function 'getSpawnRangeMax()'.
Previously, when a player respawned into a world, 'objectpos_over_limit()' was
used as a check, which was inaccurate.
Use the recently added 'saoPosOverLimit()' to get exact mapgen edges.
Also fix default value of 'm_sao_limit_min'.
These code be generated by CSM, a modded client or just copy and pasted by the player.
Changes
- Update configuration example and setting translation file.
- Remove colour codes before logging chat.
- Add setting to remove colour codes before processing the chat.
* Have the server send the player list to the client
Currently the client generates the player list based on the Client active object list, the issue with this is that we can't be sure all player active objects will be sent to the client, so this could result in players showing up when someone run `/status` but auto complete not working with their nick and CSM not being aware of the player
* Allow enabling and disabling mods.
* Re-fix 605599b6f1
This breaks some chars like € in chat.
Instead verify is char is a non control char -> iswcntrl
