Move DB path to ctx instead of static var.

@artemii235 , "dbdir" is a config parameter and we can use it directly from conf (via ctx.conf), with a helper ctx method if needed for convenience. Can you please clarify whether there is a reason to duplicate it in a ctx field? Or would the conf-based solution suffice?

@ArtemGr Hi, conf-based solution is fine, I just didn't provide the full description. There's a GLOBAL_DBDIR var that is still used by C-code, would be nice to get rid of it, however it only affects some rare test cases when we want to run multiple MM2 instances on same thread. So this is low priority task.
