This moves the "async" pathfinding computations to a worker, preparing
the architecture for threading.

This was SVN commit r22902.
Having Async in the name was not really informative and made it awkward
to reuse for non-async code.

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).

This was SVN commit r22278.
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.

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.
This was SVN commit r16867.
Also make the GetPassabilityClasses functions use references instead of
wild allocations. Use a reference when passing pass classes to the AI
worker.
This was SVN commit r16833.
Implements build limits. See #687.
Implements autorotation for dock placement.
Fixes unit spawning to consider terrain passability. See #893.
Adds new passability criteria based on distance from shore.
Updates build restrictions on some templates.
Changes unit spawning search to 4 tiles away from foundation.
Changes garrison/training spawn failure to nicer UI notification.
This was SVN commit r9970.
Pass terrain passability data to AI scripts.
Expand pathfinder passability data to 16 bits per tile, to allow more
classes.

Partially support JS typed arrays.
Allow foundations to be placed on top of units (fixes#499).
Stop farms and fishes blocking movement (fixes#534).
