HandleObstructedMove contains logic to drop long waypoints, should they
be occupied by units (because that can get the pathfinder stuck, since
the long-range pathfinder can find a path, but not the vertex one).
However PathResult already drops waypoints this way, so this code can be
removed for simplification.

This fixes a number of issues with formations:
- Gives the controller an obstruction. This fixes the bug where units in
formations can't gather from a tree.
- Stop special-casing formation members in PathResult. This fixes
formation members being stuck in-place when they run in an obstruction.
- Makes sure units stay in Formation.IDle when they are idle so that
D1337/D1901 can work correctly in the IDLE state.
- Warn if animals enter this state.
- Make sure that formation members that end up in INDIVIDUAL.IDLE go
back to FORMATION.IDLE for sanity and for better housekeeping (refs
#3144 - fixed completely upstream).

Following D1899/98f609df1d, we have logic that can handle calling
MoveSucceeded() even if we don't go through the special STATE_STOPPING
state, and following D1898/8ac104b07a we no longer need STATE_STOPPING
for animation sync either.
m_State can therefore be entirely removed as it is redundant with other
information.

After the recent UM changes, units sometimes chase/flee forever as they
can never actually get in range.
This is because moving to the current target's position is not enough
when the target is moving.
By accounting for the target movement's in ComputeTargetPosition, the
behaviour is much improved.

This is a partial revert of 4fda917f46, which skipped the
"MoveToTargetAttackingRange" in APPROACHING. I (incorrectly) assumed
that the original order was still perfectly fine, but in fact the
attacker's max range may have changed as that depends on the relative
elevation between attack and target - and so the original order might
never get us in range!
This was introduced originally in 8c74df2acd.
Add a comment to clarify this.
Further, this makes sure UnitMotion still is aware that it has a target
even if it is in range from the beginning, as that could lead
to stuckiness (and did when chasing sometimes). This was done in D1984
anyways.
Fixes#5478.

This makes it possible to merge the TryGoingStraightTo family of

This means it is now called even for point goals and decreases the
likelihood of stuck units (as we take over from the long-range

the goal).

This was SVN commit r22426.
D981/c219ee54b2 changed IsInXChecks to use edge-to-edge distance instead
of centre-to-edge, which broke UnitMotion's min-range movement, which
assumed distance to the center.
Since units are represented as squares, the diagonal point may be closer
to the target than the "real" clearance by a factor √2, so the delta
between minimum range and maximum range should be at least `(√2 - 1) *
clearance` to be safe in all situations (this is generally not a problem
for regular units which have a clearance of 0.8, but could be one for
catapults or elephants).
Differential Revision: https://code.wildfiregames.com/D1969
This was SVN commit r22422.
Previously, unitMotion had no code that checked particularly if the
target was still in the world.
When the target moved out of the world, unitMotion would follow the path
to its last known position, then send a "MoveSucceeded" message once
there.
Following 98f609df1d, this message was no longer sent. Thus unit would
follow their path to its last waypoint and stay there, unable to carry
on or finish the order. UnitMotion now explcitly sends a "MoveFailed"
message.
This still changes behaviour from A23, requiring further revisions to
UnitAI (see D1992 for one such case).
Minohaka tested an earlier version of this change (which incorporated
D1992) and accepted it.

Due to an issue in 4a15cc3b9f, animals incorrectly tried going towards
the roaming point instead of away from it.
With that fixed, MovementUpdate still did not trigger as the min and max
range were the same.
Use -1 as max range (= infinite) instead since we want to move
arbitrarily away.
Having an infinite max range was broken in c219ee54b2, this
re-implements that.
Further, other calls with equal min and max range have been changed
likewise.
This does not entirely fix whales, which run in other problems because
of their large roaming range.

Units in 0 A.D. exhibited a "gliding" behaviour at the end of a
movement, e.g. they switched to the Idle animation and still moved a
little bit.
The reason for this behaviour is that entities check if they reached
their destination after moving. Other components (unitAI mostly) will
then possibly change animations and such, resulting in a movement over
the turn while the entity is possibly now in another animation state
than "move".
Instead, what should be done is checking if the entity has arrived
before moving, so if UnitAI calls StopMoving, then entity won't move at
all on the same turn, and the gliding effect vanishes.
The STATE_STOPPING state is made un-necessary by this change, since this
off-by-one mistake was the reason for its existence. It can be removed
(see downstream).

FacePointAfterMoving intends for the unit to face the destination once a

duplications.

These variables together held the state for the target of UnitMotion, as
set by the MoveTo[X] family of functions.
Wrapping them in a struct reduces the chances that one will accidentally

Calling StopMoving() resets this target, which wasn't before and left

UnitAI is now solely in charge of moving and stopping, making UnitMotion
behaviour easier to predict, which will ultimately help with unitAI
development. It might temporarily make units more resilient than before
however.
UnitMotion also tells UnitAI that it's arrived with "MoveCompleted"
messages, but these actually could be wrong - unitAI could decide that
we didn't want to stop after all - so change the name for something less
misleading.
