2d76c81bba feat: server side knockback for AI moved objects
The client only simulates knockbacks on the character it controls
(LWOControllablePhysComponent::msgKnockback); enemies and NPCs are drawn
where the server puts them, so a knockback on them did nothing and
scripts stunned them instead.

MovementAIComponent::Knockback now flies the object the way the client
flies its character: a vector longer than 5 lifts it 0.5, throws it with
that velocity under WorldConfig gravity (times its gravity scale) until
it lands on the navmesh, no sooner than 250ms later; a shorter one moves
it by the vector. Walls taller than a step stop sideways motion, the
landing is put back onto the navmesh, and pathing and the combat AI wait
until it lands (destinations set mid air are walked to afterwards).
Position and velocity go out in the normal serialization every tick.

KnockbackBehavior builds the vector like the client's Cast (strength
capped at 300, angle as elevation, relative, caster and ignore_self) and
knocks back server moved targets that aren't immune, both when the
server casts and when a client's skill hits. The blocked bit it writes
now also answers for the target's knockback immunity, so a player whose
client hasn't caught up with a Personal Fortress isn't knocked out of it.

The AM shield generators knock enemies back like live instead of
stunning them.

* Logger: Replace calls with macros

Allows for filename and line number to be logged

* Logger: Add comments

and remove extra define

Logger: Replace with unique_ptr

also flush console at exit. regular file writer should be flushed on file close.

455f9470a5 Move EntityManager to Game namespace (#1140)
* Move EntityManager to Game namespace

* move initialization to later

Need to wait for dZoneManager to be initialized.

* Fix bugs

- Cannot delete from a RandomAccessIterator while in a range based for loop.

Touchup zone manager initialize

replace magic numbers with better named constants
replace magic zonecontrol id with a more readable hex alternative
condense stack variables
move initializers closer to their use
initialize entity manager with zone control

change initialize timings

If zone is not zero we expect to initialize the entity manager during zone manager initialization

Add constexpr for zone control LOT

* Add proper error handling

* revert vanity changes

* Update WorldServer.cpp

* Update dZoneManager.cpp

a2ca273370 Cleanup behavior bitstream reads (#888)
* Add failArmor server side

Address out of bounds reading in behavior

Address the basicAttackBehavior reading out of bounds memory and reading bits that didnt exist, which occasionally caused crashes and also caused the behavior to do undefined behavior due to the bad reads.

Tested that attacking a wall anywhere with a projectile now does not crash the game.  Tested with logs that the behavior correctly returned when there were no allocated bits or returned when other states were met.

Add back logs and add fail handle

Remove comment block

Revert "Add back logs and add fail handle"

This reverts commit db19be0906fc8bf35bf89037e2bfba39f5ef9c0c.

Split out checks
