Core/Warden: Fix crash
Fix NULL dereference crash in case Warden is disabled (in configs or on Mac OS X platform) and client sends a CMSG_WARDEN_DATA opcode
In case of dynamic file names don't store the FILE* handle in a shared class variable but keep it only at function scope.

Ignore "w" flag and always use "a" for log files with dynamic name since the file handle is created at every log line and "w" would delete any other logged line from previous _write() calls.
The best solution would be to overwrite only at first call and append at any other call.
Handle SymTagData with inner type of SymTagPointerType.
Increase buffer sizes to avoid buffer overflows.
Avoid infinite loops by logging the children of each type only once.
Avoid too deep nesting by adding a max nesting level.
Print the address for arrays instead of just the name.
Correctly handle the return value of vsnprintf() which returns -1 if the buffer is too small http://msdn.microsoft.com/en-us/library/1kt27hek.aspx . In this case just truncate the output.
This caused a crash on character delete if Logger.entities.player.dump was enabled and set to 3.
Fixes#11539
Arena season sent to client with SMSG_INIT_WORLD_STATES opcode was not sent if Player was on a zone with id 0 on login. Initializing the zone id to -1 will always trigger UpdateZone() properly on login.
Fixes#10623
Fix "DoZoneInCombat called for creature that has empty threat list" error caused by DoZoneInCombat() called by IsSummonedBy() in a script before the Creature is allowed to enter combat.
