Properly save transport related data to database when saving a Player .
On Player login update the current position as relative to transport, in case the transport moved.
Fix a database race condition between authserver saving session key to database asynchronously and worldserver reading it; session key is now saved synchronously.
- Changed default loggers and appenders
- '.' determines the relation between loggers ("type.subtype" inherits "type" logger setting if logger "type.subtype" is not defined)
- When core logs a message it search for the correct logger (root is the default one)
ie: a message logged with "type.subtype"
* Core will try to find a logger with name "type.subtype", if its not found then will search for "type", again if its not found it will return the default one "root"
Include a Helgrind suppressions file under source control. Each suppressed race is either a false positive, a read race followed by a lock acquire anyway, a bool race. Suppressions related to the same issue in the same function are grouped with a counter in brackets [ ] .
Fix tabs added in bcee801e4b .

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
