92ad6a61fa Fix OOS introduced by pathfinder threading preparation diff d592bf9cb6
Following d592bf9cb6, paths were computed at the end of turn N, and then
messages were sent at the beginning of turn N+1. However, the path
requests were removed at the end of turn N and so weren't serialised,
and neither were computed paths. This meant rejoiners would OOS when the
game was serialised with pending path results.

To fix this in preparation for threading, the architecture needs to
change slightly so that requests are kept and serialised correctly, and
rejoiners can compute the paths after deserialisation, in order to send
the messages at the beginning of turn N+1.

Fixes #5604

32b2c01c7c Decouple long and hierarchical pathfinders to an extent.
Following 809f297707, this decouples the hierarchical pathfinder and the
long pathfinder. The long pathfinder was the class owning the
hierarchical pathfinder, which didn't particularly make sense and
resulted in some interface awkwardness.

At the moment, the long pathfinder still needs to hierarchical
pathfinder to compute paths (to make sure they are reachable).

809f297707 Move the Vertex Pathfinder to its own helper class
The vertex pathfinder was implemented directly in CCmpPathfinder,
instead of being a separate helper like the hierarchical pathfinder or
the long pathfinder.

This moves it to its own helper VertexPathfinder, which gets us ready
for D14 and pathfinder threading. Some struct definitions need to be
moved around.

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.

8494e36aa8 Revert the logic change in 9da482ead4. This commit removed the checks in UnitMotion against structures, which should have been fine except the short-range pathfinder and the long-range pathfinder are not entirely compatible (check out #3532 for details). This behavior was probably slightly optimized, but it was too clever for its own good in the current state of the pathfinder, might be reintroduced later.
This resulted in ALL "units inside obstructions" issues.

Thanks to elexis for the testing.

Fixes #3532, #3450.

formations, but this is only aesthethic.)

9da482ead4 Based on previous experimental changes, major update to the unit motion.
With this change, units will not check their movement against all
obstructions when moving: terrain and static obstructions are assumed to
be handled by the long-range pathfinder.
However, when static obstructions are changed, the paths have to be
invalidated. In order to minimize the performance impact, units will
check for obstructions when they move after a passability change. If
they collide with something, they will recompute a path that will take
into account the new passability map.

Also includes some code cleanup. This patch should not change
performance a lot: the lower number of checks should give a small
performance improvement while using the message broadcasting system
should hurt it a bit.

f134ac63bb Revert most of f240374b28 which was actually bad. It caused units to get stuck because the obstructions won't block the same paths when rasterized on the grid and when directly tested for collisions.
As a general rule, pathfinding-blocking shapes should not be tested
against for movements. Only the passability grid should be considered.
As the algorithm which tests paths on this grid was fixed in 1c9ea56800,
it can be safely used.

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.
