Fix chunk block changes being sent out of order (#5169)
* Flush out all pending, buffered changes at the end of each tick, after every chunk is ticked. This makes every block update client-side in unison, instead of unlucky ones only being sent 1 tick later.
* Re-add buffer for outgoing network data; IOCP async WSASend has higher overhead than expected... Fixes regression introduced in 054a89dd9

054a89dd9e Clarify cClientHandle, cPlayer ownership semantics
+ 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.

Use tracing for explosions (#4845)
* 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

* TNT: pull block destruction into common function

99856df686 Add WakeUp/AddBlock distinction
* WakeUp is for singular changes (block breaking for example). The simulator should check blocks around the position and discover other affected blocks as it sees fit
* AddBlock is for when you know a whole area is to be updated; chunk loading, or area wakeups for example
+ Prepares for correct handling of destroyed blocks after removal of SolidBlockHandler in the redstone simulator

Pulled the BlockID and BlockInfo headers from Globals.h. (#4591)
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

Optimise chunk set (#4260)
Closes #1244

Initially I was just going to add the cChunkData to cSetChunkData but profiling revealed 
that the copying wasn't even the biggest slowdown. Much more time was being spent in 
cChunk::CreateBlockEntities and cChunk::WakeUpSimulators than was in memcpy so I've made 
those significantly faster as well.

Optimisations performed:
 * cSetChunkData now stores blocks in a cChunkData object
 * cChunkData objects can now perform moves even if they are using different pools
 * cChunk::CreateBlockEntities now iterates in the correct order and only over present chunk sections
 * Similarly for cChunk::WakeUpSimulators
 * cSetChunkData::CalculateHeightMap now shortcuts to the highest present chunk section before checking blocks directly
