* Re-number enums by function groups and use where possible new defined masks in code instead raw enum |-lists.
* Avoid use movement generator generic state markers like UNIT_STAT_CONFUSED for mark movement stoped.
Add special shadow UNIT_STAT_CONFUSED_MOVE/etc states for like use.
UNIT_STAT_CONFUSED in like case will be safe expect use for normal checks confused state presence
And UNIT_STAT_CONFUSED_MOVE for check real move in this state
use an extra function for setfeigndeath()
like it's done with setfeared already..
allow to apply feigndeath on creatures too
avoid moving of creatures with feign death applied
and start attacking last victim when feigndeath disappears
* Create new monster move field in Creature class and use it in all cases when expected use MONSTER_MOVE_* flags.
* Store and use MOVEMENTFLAG_* values in field in MovementInfo structure of Player class.
* Cleanups and fix related code.
NOTE: DB in creature_addon store values similar MONSTER_MOVE_* flags, scritps also expected set only this flags.
Including fix _SCallback for 3 params, triggred mode correct call for .cast back and .cast target.
Remove outdated code for support old 19421 (and ranks) implementation in client data.
