* Combat/Threat rewrite (PR #19930) prep work. Mostly refactors, and a compatibility layer on ThreatManager/HostileReference that allows scripts to be changed already.
* *PCH.cpp are now only compiled with MSVC, other compilers use custom helper commands to generate the precompiled header
* Don't call the linker for pch helpertargets
(cherry picked from commit 137f5e7887)
- Move on-create customs (all explored, all reputations) to CharacterHandler::HandlePlayerLogin for first login. Fixes#19839.
- Add Wrath factions to all reputations custom (it only had BC factions).
- Remove unused ReputationMgr::SendStates. Add ReputationMgr::SendState handling for sending all updated states in arbitrary order if nullptr is passed (used in point #1).
- Fix all weapon skills max custom to properly apply on learning new weapon skills.
- Now only requires the either target's group leader or target itself to be on your map
- Now summons all applicable group members even if one member fails checks
- No longer has some truly weird edge case instance unbind code that could cause exploit behavior (Really, I have no idea why this existed, because it certainly didn't do what it might've been meant to do.)
Then it turned out that gameobject LoS is already fixed. So all this does, really, is restructure some stuff.
And remove the hack from Sapphiron because I could.
* Add new method Map::getFullVMapDataForPosition to get area info and liquid info in a single vmap lookup
* Use this lookup in Map:: relocation methods to update m_areaId and m_zoneId fields on WorldObject
* Adjust GetZoneId/GetAreaId on WorldObject to always return these cached fields
* Clean up liquid state handling on Unit and Player
* Hand floor's Z coord up through GetFullTerrainStatusForPosition, use it to update a new field in WorldObject, and use that to feed a new GetFloorZ call on WorldObject.
Closes#16489
* Pet/Guardian AI hook re-organizing:
- Adjust OwnerAttacked/OwnerAttackedBy hooks on CreatureAI to fire for all owned units, not just player pets. This should allow guardians to more reliably recognize valid targets.
- Kill off the AttackedBy hook. While it was defined in CreatureAI.h as virtual, it was only ever invoked for player pets in specific situations. This makes it classic developer bait.
- Adjust PetAI to use DamageTaken instead of AttackedBy.
- Adjust behavior of AttackStart on PetAI to compensate.
