(cherry picked from commit 5c1fc5e387)
Unit::StopMoving() is evil, and so is MotionMaster::Clear()
the first can really mess up existing movement generators
the second can interrupt "controlled" movements... can do it literally mid-air
(cherry picked from commit c826ec0a3c)
- PvE combat is now always mutual. UNIT_FLAG_IN_COMBAT is backed by actual references to the units we're in combat with.
- PvP combat is now also tracked, and almost always mutual; spells like Vanish and Feign Death can break this rule. That means we can easily determine a list of players we're fighting.
- By extension, IsInCombatWith now has sensible behavior when invoked on nonplayers.
- Threat and combat systems are no longer the same.
- They still have an enforced relationship (threat implies combat - clearing combat clears threat)...
- ...but we can have combat without threat. A creature (with threat list) isn't considered to be engaged until it has an entry on its threat list...
- ...which means we can now faithfully replicate retail engage behavior. Combat on projectile launch - engagement start on projectile impact. Yay for progress!
- AI method refactor, as already ported in 6113b9d - `JustEngagedWith`, `JustEnteredCombat` and `JustExitedCombat`.
- Vehicle threat is now properly pooled on the main vehicle body (fixes#16542).
- Various edge case bug fixes for threat redirects (Misdirection "cancelling" Vigilance and similar).
- Target re-selection is now significantly faster.
- Fixed a ton of other smaller edge case bugs, probably.
Closes#7951 and #19998.

Core/Spell: The giant CastSpell unclusterfucking (that's a word now) of this generation.
- CastSpell now always takes three arguments - target, spellId, and a struct containing extra arguments
- This struct (CastSpellExtraArgs, see SpellDefines.h) serves as a conglomerate of every previous combination of the 20 billion different CastSpell overloads, all merged into one
- It has some great utility constructors - check them out! All of these can be used to implicitly construct the ExtraArgs object.
- A gajillion refactors to make everything behave the way it always has
(cherry picked from commit d507a7e338)
* 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.

Set in front modifies only the serverside orientation, use with care.
Also check for current focus to prevent things like incorrect damage on casting creatures (ie dragon breath direction change in your face because of some taunt missclick)
(cherry picked from commit 229444b74a)
* Mostly aimed at removing Log/DatabaseEnv includes from other headers
* Fix most packet headers including other packet headers - moved common structures such as ItemInstance to their own files
* Moved SAI function definitions to source files (massive or requiring many different dependencies)
