jackpoz be7d82ba8d Core/Maps: Fix Spline triggered assert
Fix an assert triggered by float to int32 cast overflowing to -1, now it replaces -1 with max int32 value.
Fix another assert triggered by Vector3 magnitude float overflow to max/infinity in StaticMapTree::isInLineOfSight(), in this case return false.

Both asserts can be reproduced by casting Mind Control to a NPC, tele to z: 1.0e+38 using client hack tools, move to allow the server to register the new position and stop Mind Control.

jackpoz 2a47b602d7 Core/Aura: Fix SPELL_AURA_BIND_SIGHT invalid read
Mind Vision has Aura Effect SPELL_AURA_BIND_SIGHT which adds the target to a special Map container i_objectsToSwitch, used to switch grid containers for target Creatures of this Aura Effect.

When the target is a Creature, when the Creature is removed from world it's added to i_objectsToSwitch and then to i_objectsToRemove, iterated in this order in Map::RemoveAllObjectsInRemoveList() so the reference in i_objectsToSwitch is valid.
When the target is a Player, when the Player logs out it's added to i_objectsToSwitch but then Map::RemovePlayerFromMap() deletes the Player, leaving an invalid reference in i_objectsToSwitch.

Since the whole point of i_objectsToSwitch is to store Creatures and since the stored references are used only if the condition "GetTypeId() == TYPEID_UNIT" is verified, it's safe to add only objects of TYPEID_UNIT type to the container.

jackpoz 21459739c6 Fix uninitialized UpdateMask field
Initialized UpdateMask::_bits to NULL in all constructors.
UpdateMask(UpdateMask const& right) constructor sets the field count with SetCount() method before any field initialization. This means that SetCount() will call delete[] on the uninitialized _bits pointer field, leading to undefined behavior.
