HullHider gets a hideEntities parameter: the fight still hides entities inside
hidden hulls, /hullhider only hides blocks. As the TechHider also dropped
spawn packets at hidden positions, ForPlayer#canAccessEntitySpawn decides
about them now, which the BauTechHider always allows.
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.
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.
