- Implement DatabaseWorkerPool::DirectCommitTransaction for synchronous transaction execution (as opposed to asynchronous/enqueued).
- Add MySQL errno 1213 "Deadlock found when trying to get lock; try restarting transaction" handler. If 1213 is called the core will retry to directly execute the transaction a maximum of 5 times.
- Separate rewarded quests from active quests, and store them in a new table to reduce database size
- Drop the no longer needed `rewarded` column from character_queststatus for smaller table size
- Prevent filling the database with dropped quests
- Delete useless records
- Implement queststatus save "queues" instead of states
- Minor optimizations
WARNING: Backup your database!

branch : trunk
- Add generic HandleMySQLErrno() method.
- Add the ability to re-execute a certain statement if errorhandler resolved the situation succesfuly.
- Add support for MySQL errno´s 2006, 2013, 2048, 2055 - fixes automatic reconnection behaviour.
- Cleanup in affected code
NOTE: You should still be smart enough to configure your worldserver and authserver´s MaxPingTime to be lower than your MySQL´s wait_time.

branch : trunk
As a side effect moved related queries to prepared statements.
As one more side effect fixed not shown and lost mail items in returned expired mail (patch by Quriq14).

- Declare some functions const
- Fix some mem leak
- Fix some resource leak
- Remove unused variables and functions
- Remove duplicate functions
- Reduce the scope of some variables
- Remove unused file

branch : trunk
- Make time format of MaxPingTime consistent between authserver and worldserver. Note that the value is in minutes, update your config files accordingly if needed.
- Remove obsolete atomic uint32 and prevent concurrent calls to vector::size() in DatabaseWorkerPool

branch : trunk
- Make the mysql connectionpool shared for async and syncrhonous connections.
- Allow configurable amount of connections for the pool
- Allow configurable amount of delaythreads
Note that delaythreads now only represent in-core threads. Whenever they execute a task they will pick a free connection from the pool instead of using their previously unique assigned connection.
The purpose of this design change is better distribution of SQL requests (no bottlenecks paired with idling) among available resources.
This also prevents a ¨memory waste¨ of preparing async prepared statements on synchronous connections (that were never called) - and vice versa. Now, connections aren´t explicitly async or synchronous, they serve both purposes.
Use at own risk, might cause instabilities.
Don´t forget to update your config files and clear your cmake cache.

*** TO PRESERVE (COPY) THE DATA CONTAINED IN THE OLD TABLES, YOU MUST FOLLOW THE FOLLOWING SQL-RECIPE (REPLACE DATABASENAMES WHERE NEEDED!) ***
-- Move creature_respawn from world to characters db
INSERT INTO `characters`.`creature_respawn` (`guid`, `respawntime`, `instance`)
SELECT `guid, `respawntime` `instance` * FROM `world`.`creature_respawn`;
-- Remove creature_respawn table from world db
DROP TABLE `world`.`creature_respawn`;
-- Move gameobject_respawn from world to characters db
INSERT INTO `characters`.`gameobject_respawn` (`guid`, `respawntime`, `instance`)
SELECT `guid`, `respawntime`, `instance` FROM `world`.`gameobject_respawn`;
-- Remove creature_respawn table from world db
DROP TABLE `world`.`gameobject_respawn`;
-- Move reserved names from world to characters db
INSERT INTO `characters`.`reserved_name` (`name`)
SELECT `name` FROM `world`.`reserved_name`;
-- Remove reserved_names table from world db
DROP TABLE `world`.`reserved_name`;
*** THE ABOVE MUST BE DONE, OR EXISTING INSTANCES WILL BE FULLY RESPAWNED - YOU HAVE BEEN WARNED ***
Closes issue 4842. Closes issue 4849.
