Map local guids 6.x -> 3.3.35:

Implemented:
  https://github.com/TrinityCore/TrinityCore/commit/ca83e14f8b141fab0a13e08f48fca6c1ace0c4c7
  https://github.com/TrinityCore/TrinityCore/commit/ee1c1b97be4492ecabe8b15ea6323fc37e4eaa8c
  https://github.com/TrinityCore/TrinityCore/commit/18e4ab6911468b829b0fc768e532a770263c3717

  https://github.com/TrinityCore/TrinityCore/commit/cb854a2b7bb7bd96cf9c4d1daf3789f797bf4db8

* 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.
