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.
+ A cPlayer, once created, has a strong pointer to the cClientHandle. The player ticks the clienthandle. If he finds the handle destroyed, he destroys himself in turn. Nothing else can kill the player.
* The client handle has a pointer to the player. Once a player is created, the client handle never outlasts the player, nor does it manage the player's lifetime. The pointer is always safe to use after FinishAuthenticate, which is also the point where cProtocol is put into the Game state that allows player manipulation.
+ Entities are once again never lost by constructing a chunk when they try to move into one that doesn't exist.
* Fixed a forgotten Super invocation in cPlayer::OnRemoveFromWorld.
* Fix SaveToDisk usage in destructor by only saving things cPlayer owns, instead of accessing cWorld.
- Removed RemoveFromAllChunks. On destruction cWorld::RemovePlayer calls RemoveClientFromChunks already, and there's no need to manually clear the chunk lists.
* 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
* Tried to fix a small issue...
Ended up rewriting a bunch of god awful, opaque code with no source
and no sense. Who names a function GetPlayerRelativeBlockHardness???
It's gone now. We're safe again.
* Testing anti-cheat.
* Tidy up debug logging.
* Remove empty member declaration.
* Rewrite GetDigSpeed slightly for better readability.
* GetMiningProgressPerTick now returns 1 when instantly mined. Fixed hasily written typo.
* Comment style and typo fixes.
* Use lapis for enchanting, subtract correct number of levels, ClientHandle now selects from pregenerated list.

* BlockHandler initialisation is a constant expression
If we can't make it all namespaces, this is the next best I guess.
+ Tag handlers constexpr, const as needed
+ Inherit constructors
* Privatise handler functions
* More constexpr

* TNT: Implement tracing algorithm
+ Add intensity tracing
* Fix iterating over all players to SendExplosion, even those not in range
* Implemented TNT entity interaction
* Fixed misaligned destruction tracing
* Finalise TNT algorithm
- Remove BlockArea and just use chunks
Using SetBlock makes it so that we can update everything properly, and does appear to be faster.
* BlockInfo learns about explosion attentuation
* Rename Explodinator parameters

* 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

The BlockID.h file was removed from Globals.h and renamed to BlockType.h (main change)
The BlockInfo.h file was removed from Globals.h (main change)
The ENUM_BLOCK_ID and ENUM_ITEM_ID enum names were replaced with ENUM_BLOCK_TYPE and ENUM_ITEM_TYPE (cosmetics)
The various enums, such as eDimension, eDamageType and eExplosionSource were moved from BlockType.h to Defines.h, together with the helper functions for converting between them and strings (StringToDimension et al.) (minor)
Many inline functions were moved from headers to their respective cpp files, so that BlockType.h could be included only into the cpp file, rather than the header.
That broke our tests a bit, since they pick bits and pieces out of the main code and provide stubs for the rest; they had to be re-stubbed and re-verified.
eMonsterType values are no longer tied to E_ITEM_SPAWN_EGG_META_* values
* Replace buckets to the selected hotbar slot, rather than the first available.
Replicates vanilla behaviour, as well as being more logical.
* Refactor cInventory::AddItem. Behaviour is now documented
* Add new cInventory::ReplaceOneEquippedItem and ::SetEquippedItem methods
* Return empty potion to the same slot after drinking
* Replace buckets correctly in other situations, not simply water and lava
Uses the new ReplaceOneEquippedItem method
* Correct collecting water from source block with bottle
* Add cPlayer::ReplaceOneEquippedItemTossRest method
* Handle stacked filled buckets (in theory)
Use new cPlayer::ReplaceOneEquippedItemTossRest method
* Wrong overload of function push() got called when pushing a cEntity*.
Using a const cEntity * fixes this.
* Fixed accidental wrong indentation
* Compiler didn't like old style cast
* Kicking player when writing chat message longer than 2048
* Accounted for Astrings size() method returning bits, not bytes
* Fixed typo

* Stabilise MoveToWorld
* Fix comments and deprecate ScheduleMoveToWorld
* Enhanced thread safety for m_WorldChangeInfo
* Return unique_ptr from cAtomicUniquePtr::exchange
* cWorld now calls entity cEntity::OnAddToWorld and cEntity::OnRemoveFromWorld.
Allows broadcasting entities added to the world from the world's tick thread.
This also factors out some common code from cEntity::DoMoveToWorld and cEntity::Initialize.
As a consequence, cEntity::Destroy(false) (i.e. Destroying the entity without broadcasting) is impossible.
This isn't used anywhere in Cuberite so it's now deprecated.
* Update entity position after removing it from the world.
Fixes broadcasts being sent to the wrong chunk.
* Fix style
* cEntity: Update LastSentPosition when sending spawn packet
* Add Wno-deprecated-declarations to the lua bindings
* Kill uses of ScheduleMoveToWorld
