40ef9cbf2f [11284] Implement prepared statements for INSERT+DELETE+UPDATE SQL requests. Should improve player save performance + lower MySQL server CPU usage. 
Note: PostgreSQL does not have prepared statements implemented using native APIs.

Huge thanks to Undergarun, kero99 and Vinolentus.

fce48282ad [11061] Bring 'autocommit' mode for MySQL back. This MySQL feature operates in so frustrating way so it is better to keep it ALWAYS ENABLED!!!

d67219e327 [11059] Fix crash in [11054]. As it turned out - we use not only async transactions but async queries too during server startup =/

07c9f0cbb8 [11054] Do not allow async transaction execution while server is loading. Call Database::InitDelayThread() function explicitly to create async DB worker thread after server initialization is complete.

631ce36680 [11045] Rewrite internals of DB layer. Simplify code and use less locking. Spawn and use separate connections for sync and async DB requests. Implement database connection pool for SELECT queries. Up to maximum 16 connections supported. Disable 'autocommit' mode for MySQL. 
UPDATE YOUR CONFIGS!

Defaults:
LoginDatabaseConnections = 1
WorldDatabaseConnections = 1
CharacterDatabaseConnections = 1

If you are not using <mtmaps> patch do not change the default settings - this is useless. You can try following option in your MySQL config to squeeze even more performance from your DB:

[mysqld]
transaction-isolation = READ-COMMITTED

Great thanks to Undergarun, kero99 and selector for making tests and providing very useful feedback and DB statistics! Have fun :)

8a7b77c088 [8441] Implement check DBs versions (required_* fields) at mangosd/realmd loading. 
* git_id updated to generate revision_sql.h file with required_* fields strings.
* mangosd/realmd changed to include header and check this strings at startup.
* mangosd/realmd will terminated if related strings not match in DB content.
  In most cases this meaning that not all expected sql updates applied.
  Current required_* field stored in DB output in error to help find what last sql updates applied.

IMPORTNAT NOTE for mangos devs: please update used git_id before adding next commits with sql updates!
