Add additional assert to assure that helgrind reports related to SQLQueryHolderTask::Execute() and WorldSession::ProcessQueryCallbacks() are false positives.
The only chance for WorldSession::ProcessQueryCallbacks() to access the SQL queries before they are completed is if m_result.ready() is true before the end of SQLQueryHolderTask::Execute() .

* Fixed fall damage on transports while teleporting
* Fixed packets not being received by owner if sent by a controlled minion
* Fixed an issue when a teleporting transport would attempt to reload its creature passengers on old map
Closes#11140
Allow to add overlapping teles like "abc" even if "abcde" already exists. This wasn't possible and a "Teleport already exists" error was thrown instead.
Fix uninitialized Docks timer in Isle Of Conquest .

Remove assertion about Quest ExclusiveGroup since they are triggered even when adding valid quests to npcs. Fixes#8336 .
How to reproduce steps:
- .gm off
- add quest 11335 in creature_queststarter
- .reload creature_queststarter
- get in range of that creature
- .gm on
- assertion triggered
Mitigate DoS attacks like one explained in #10555 by processing a limited number of packets at each WorldSession::Update() call, allowing other WorldSessions to be processed.
100 packets in a single update sound like a reasonable amount.
