First one: add missing exception handler in ProcessProtocolIn
Second: remove faulty logic dealing with incomplete packets.
`a_Data = a_Data.substr(m_Buffer.GetUsedSpace() - m_Buffer.GetReadableSpace());`
was incorrect; it attempted to apply a length derived from m_Buffer to an unrelated a_Data. Its purpose was to give cProtocol the data the client sent, minus initial handshake bytes. However, we can use the knowledge that during initial handshake, there is no encryption and every byte can be written unchanged into m_Buffer, to just call cProtocol with a data length of zero. This will cause it to parse from m_Buffer - wherein we have already written everything the client sent - with no a_Data manipulation needed.
Additionally, removed UnsupportedButPingableProtocolException (use of exception as control flow) and encode this state as m_Protocol == nullptr, id est "no protocol for this unsupported version", which is then handled by cMultiVersionProtocol itself.
* Turn off global-constructors warning. These are needed to implement cRoot signal handler functionality
* Add Clang flags based on version lookup instead of a compile test. The CMake config process is single threaded and slow enough already
* Reduced GetStackValue verbosity
+ Clarify EnchantmentLevel, StayCount, AlwaysTicked, ViewDistance signedness
+ Give SettingsRepositoryInterface a move constructor to simplify main.cpp code
- Remove do {} while (false) construction in redstone handler
* Use lapis for enchanting, subtract correct number of levels, ClientHandle now selects from pregenerated list.

* Introduce recipe book functionality
The recipe book helps especially new players. Missing it gives the
impression that cuberite is not as advanced as it is.
The handling of the recipe book uses the following functions:
- Unlock Recipes
(https://wiki.vg/index.php?title=Protocol&oldid=14204#Unlock_Recipes) to
make recipes available and show the notification for new recipes.
Initialization is done on player login for known ones, the update is done
when new items are discovered.
- Craft Recipe Request
(https://wiki.vg/index.php?title=Protocol&oldid=14204#Craft_Recipe_Request)
when the user selects a recipe from the recipe book to fill the slots.
Known recipes are initialized on player login via `Unlock Recipes` with
`Action` 0.
As soon as a new recipe is discovered this is added via `Unlock Recipes`
with `Action` 1.
To be able to know and recognize new recipes the player class is
extended with `KnownItems` and `KnownRecipes`. As soon as a player
touches an item this is compared to the list of `KnownItems`, if the
item is unknown the recipes are checked for this item and the other
ingredients are checked with the list of `KnownItems`. If a full match
is discovered the recipe is unlocked with the client and stored in the
`KnownRecipes`.
To unlock recipes the recipe ID is sent to the client. A mapping file
(for protocol 1.12.2) translated the minecraft recipe names to ids. The
crafting.txt is extended with and minecraft recipe names is possible.
Limitations:
Only a single recipe is added to the crafting area. Multiple clicks or
shift click does not increase the number of builds.

* Address first issues mentioned by @peterbell10
- Some linting
- Extract loading of recipe specific protocol mapping into a function
- Build `RecipeNameMap` only once
- Use `std::optional`
- Extract `LoadRecipe` from `Window`
* Start to implement new suggestions
* Update with suggestions from @peterbell10
* Some minor cleanup
* Update protocol packet IDs
* Remove unused include
* Include header in cmake
* Change a vector to integer counter
* Change dromedaryCase method names to PascalCase
* Address suggestions from @madmaxoft

To load all recipebooks iterate over the `Protocol` subdirectories
to find mapping files.

Closes#4236
CMake now creates a header file in the build directory under the path "include/Globals.h" which just includes "src/Globals.h" with an absolute path. Then instead of adding "src/" to the include directories, it adds "include/".
#include "Globals.h" still works by including the build generated file and any other src-relative path will not work.
This is my attempt to fix#4112. The root cause of the issue was that the lapis slot was treated exactly the same as the enchanting slot, so it on the server side it would only ever slot one item.
My fix is to check if its the second slot in the window, then check if it's lapis (it would slot whatever). If it is lapis I call the base click handler.
* Replace cWorld::FindClosesPlayer with cWorld::DoWithClosestPlayer
* Implement experience reward splitting into the orb sizes used in vanilla
* Modified speed calculation in cExpOrb::Tick to make the orbs fly towards the player
Fixes#4216
* Change reinterpret_cast -> static_cast wherever possible
* Remove more unnecessary `const_cast`s.
reinterpret_casts should be avoided for the same reason as c-style casts - they don't do any type-checking. reinterpret_cast was mainly being used for down-casting in inheritance hierarchies but static_cast works just as well while also making sure that there is actually an inheritance relationship there.
