long overdue... this isn't quite as extensible as the original api3/blocks system was, but this is primarily intended to replace Item->useOn(). If plugins want to use it it can be extended later on.
This is basically how blockstate discovery would actually work in the full-blown system. This maps blocks with unrecognized blockstates to static runtimeIDs not known to the client.
This means that all blocks which don't have corresponding runtimeIDs in the new system will translate to update! blocks instead.
Mojang do this differently: they try to a) match id+meta, if that fails b) match id+0, and if that fails, then replace with update! block runtime ID. I can't do that here because I need to be able to convert both ways. They only need to be able to convert from legacy -> new.
This allows the removal of lots of ugly code, and also exposes lots of similarities with how this update type was handled. This can be further improved in the future to more generically handle cases.
I realized in the process of changing this, that it might actually be simpler to treat to treat scheduled updates and neighbour updates as one and the same. They use the same mechanism for being saved on chunks (TileTicks),
and doing that would make updating only require one queue instead of two.

this is not technically correct behaviour, but this preserves the current behaviour.
These are never called accidentally, or at least it's highly unlikely to do so. It might be reasonable to throw exceptions for this, but for the meantime they are redundant - extra indentation for no good reason.
This also removes the $force parameter from BlockFactory::init().
MOP doesn't make any sense anyway.
RayTraceResult is a container which represents the point at which a line hits a bounding box. No dependence on blocks or entities is wanted or needed.
MovingObjectPosition has API changes to allow it to wrap RayTraceResult, but nothing uses MOP anymore anyway.
This would allow modularisation of the pocketmine\\math namespace.
This now removes the need for recursing around for structures comprised of multiple blocks. Instead, override getAffectedBlocks() to return all blocks that need to be deleted when the current block is deleted, and make sure that only one half of the block drops something. When a player breaks one of the blocks, all the blocks affected by that block will also be destroyed, creating particles and sounds where appropriate.
This fixes creative drops for double plants and beds.
