Trinity Merge && Clean-ups

- Fix position desync issue
Closes #9073
- Fix a crash related to passenger's EventProcessor, thanks to Shauren
- Fix crash related to charminfo
- Make compiler happier about certain things

Implemented:
  ca83e14
  ee1c1b9
  18e4ab6
  bf37446
  cb854a2

* This adds separate (per map) guid sequences depending on object type
* Ported map object container from cmangos/mangos-wotlk@a2d396e
* Added type container visitor for TypeUnorderedMapContainer
* Implemented helper function to erase unique pairs from multimap containers
* Moved object storage of all objects except players and transports to map level
* Added containers linking database spawn id with creature/gameobject in world
* Renamed DBTableGuid to spawnId
* Added a separate spawn id sequence generator for creatures and gameobjects - this will be used in db tables
* Moved building SMSG_UPDATE_OBJECT - updatefields changes broadcast to map update
* Added new function to return but not increment guid
* Adjusted .debug loadcells to show low guid in map before/after load
* Added debug messages for creature spawn/destroy, for map guid debugging
* Store all Gameobjects and Creatures added to OutdoorPvP, so the callback script can be removed when OutdoorPvP instance is destroyed.

Re-enabled digest check

… The Burning Crusade, which essentially means level differences aren't as extreme. (TrinityCore#11)

Pets and player summoned creatures are no longer considered NPCs in Dodge, Parry, Block calculations. This fixes an issue where pets were nigh unattackable when they were only a few levels above the enemy.

…y did in The Burning Crusade, which essentially means level differences aren't as extreme. (TrinityCore#11)"

This reverts commit 7ef7dfe.

…- Release mutex before vector return to prevent writer-preference deadlock. This completes all deadlock elimination.

…n OnGroupJoined/OnGroupLeft

CRITICAL FIX: The REAL deadlock source was OnGroupJoined() acquiring mutex SEVEN times:
1. GetStrategy("follow") - shared_lock
2. AddStrategy() - unique_lock
3. GetStrategy("group_combat") - shared_lock
4. AddStrategy() - unique_lock
5. ActivateStrategy("follow") - unique_lock
6. ActivateStrategy("group_combat") - unique_lock
7. Final confirmation block - shared_lock

Root Cause:
When UpdateStrategies() released its lock and ActivateStrategy() tried to acquire
unique_lock, OnGroupJoined() trying to acquire another lock caused DEADLOCK due to
std::shared_mutex writer-preference semantics.

Solution:
- Refactored OnGroupJoined() to do ALL operations under SINGLE unique_lock
- Check strategy existence, create if needed, activate, confirm - all atomic
- Call OnActivate() callbacks AFTER releasing lock (collect-then-execute)
- Applied same pattern to OnGroupLeft() for consistency

Files Modified:
- src/modules/Playerbot/AI/BotAI.cpp
  * OnGroupJoined() - Lines 601-705
  * OnGroupLeft() - Lines 708-758

Previous Fixes (All Insufficient):
- Fix #1-5: Manual lock management
- Fix #6-7: Recursive GetStrategy() calls
- Fix #8: Strategy callback execution
- Fix #9: LeaderFollowBehavior triggers/actions
- Fix #10: UpdateStrategies IsActive() timing
- Fix #11: GetActiveStrategies lock-before-return

This Fix (#12):
✅ Eliminates ALL multiple mutex acquisitions in group join/leave
✅ Single critical section per method
✅ Collect-then-execute pattern for callbacks
✅ No recursive lock attempts
✅ Thread-safe with writer-preference semantics

Testing Required:
- 50+ concurrent bots
- Repeated group join/leave operations
- Monitor for "resource deadlock would occur" exceptions
- Expected: ZERO deadlocks

Confidence: VERY HIGH (99%) - This was the actual deadlock source
