The new TechHider registers a permanent global filter, so BauSystem now uses
a single BauTechHider that combines the hiding rules of the spectator
techhider, /techhider and /xray per player. To support the different
obfuscation blocks of these rules, ForPlayer now provides the obfuscation
block per position.
The ChunkHider now also checks single valued chunk sections, which were sent
unfiltered before, and recalculates their block count if they change.
Unhandled packet types are logged once; statistics, debug samples and ping
responses are passed through.
The legacy TechHider and its access widener entries are removed.
ObfuscationConfig resolves the hidden blocks, block states (including all
waterlogged states when water is hidden) and block entity types plus the
obfuscation block, either from a gamemode's techhider config or from plain
materials. TechHiderWrapper now only contains the fight specific access rules.
Hull no longer depends on FightSystem: plugin, world, region, ground
visibility and hidden blocks are passed in. HullRegion is the common block
box hulls work on. The generic HullHider<K> manages one hull per key and does
the block, entity and REntity tracking; FightHullHider keeps the fight
specific parts (team hulls, viewer rules, state dependent registration).
Entities are now checked against the hull with block coordinates, so entities
in the bottom layer and at the max z edge are handled correctly.
HiderCore holds the TechHider, ChunkHider and AccessPrivilegeProvider so that
FightSystem and BauSystem can both shade it. BlockIds and ProtocolUtils stay in
SpigotCore (used by AntiNocom and RFallingBlockEntity) and move to
de.steamwar.core to avoid a split package. The access widener entries the
TechHider needs are duplicated into hidercore.accesswidener; the legacy
TechHider still needs its own copies in SpigotCore.
