5c642611c4 Vertex pathfinder - fixes to quadrant optimisation to ensure units don't take detours around obstructions.
Compute the outward quadrants once and for all instead of setting them
dynamically, because there is no reason why we should always arrive from
the same quadrant as the first time we see a vertex.
Don't consider quadrants for the start-vertex, because of the edge
expansion (which can put us in illegal quadrants)

These result in (much) better paths, the tradeoff being that we now look
at some more vertices.

Fixes #5476

58018a1056 UnitMotion - rename CheckTargetMovement to PathingUpdateNeeded for clarity, and improve the logic.
This new version compares the final waypoint with the target's
obtruction shape and uses reachability checks to know if we will be in
range or not.

f42d97c6f3 Fix some animals "roaming" state not working correctly (units seem stuck in place)
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.

c219ee54b2 Move "IsInRange" family of functions to the Obstruction Manager and make the commutative.
These functions were placed in UnitMotion, which had nothing to do with
range checks and made them available only to moving entities for no
particular reason.

This patch also adds support for square-square range checks and
shape-shape distance checks.

Modified from a patch by bb on top of work from wraitii.

357203a90f Pathfinding changes: unit-unit collisions now allow for some overlap, so units can get closer to each other, which I found improved pathfinding considerably.
Also fix a potential issue I noticed in some cases, though that
particular fix implies scrapping waypoints, so if units seem to get
lost, please report so and I'll revert those changes.

I can't find any way to get units stuck with this patch.

have side-effects: please report anything weird.

ae6475fcc0 Fix a typo, patch by godlikeldh.
This typo didn't have any influence since dirty unit shapes are usually
discarded during the rasterization (they don't block long-range
pathfinding). Switching the order of a check in RasterizeHelper prevents
performance problems to a really small extent.

128a603287 Use the terrain-only grid for terrain edges in the short pathfinder algorithm. This grid is updated on each terrain change, whereas the passability grid is updated once a turn. This caused OOS on rejoin, fixes #3292.
However, using the terrain-only grid reveals one discrepancy between the
short pathfinder (which uses unit radii) and the long one (which uses
unit clearances). So I implemented the change proposed by sanderd17 in
#3294, which is removing unit radius and using only the pathfinder
clearance. Refs #3294
Now some tweaking has to be done in the templates, so that units get a
passability class suited to their apparent size. In the meantime the
unit motion is quite bugged.

db39d742f0 Fix units falling off the edge of the world.
I guess changes to the map loading sequence caused the TerrainChanged
message to be sent before the map was switched from square to circular
instead of after. The pathfinder didn't notice the switch, so it
continued treating the map as if it were square, allowing units to walk
into the permanent map-corner SOD and vanish, and allowing territories
to expand into the SOD.

Tell the pathfinder explicitly when the map shape changes, so it can
discard its cached data correctly.

4663ac0fe7 split debug_assert into ENSURE and ASSERT as discussed in a previous meeting.
the old debug_assert always ran and tested the expression, which slows
down release builds. wrapping them in #ifndef NDEBUG is clumsy. the new
ASSERT behaves like assert and ENSURE like the old debug_assert. Let's

speed up release builds. (already done in bits.h and unique_range.h)
