[patch][8339] Improved storing/restoring BG entry point

[ApoC]

What bug does the patch fix? What features does the patch add?

* Introduced new table character_battleground_data

* Entry point is now stored on BG enter event not join event

* Entry point for dungeons is now correctly set to nearest graveyard

(this prevent well known assert in GetInstance because of porting to already destroyed instance)

* Teleporting from BG correctly restore mount state

* Teleporting from BG correctly restore taxi flight

(in multipath flight you will end up in nearest transition point on the route)

Any chance to see this in mangos-0.12 soon?

[VladimirMangos]

for mangos-0.12 only table creating make sense maybe. In 2.4.3 work another way save position: always seelcted leader position in moment BG registering near BG master.
