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.

11c9471ad6 Change back the long pathfinder to take into account non-pathfinding classes, but only when reloading, to avoid impacting the performance.
Also make the GetPassabilityClasses functions use references instead of
wild allocations. Use a reference when passing pass classes to the AI
worker.

1709353e2c Changes the general behavior of non-pathfinding passability classes, in order to make the handling of foundation obstructions less difficult. This will allow the AI to be fixed, as reported in #3295.
Also some cleanup and comments updates.

6581796103 New long-range pathfinder.
Based on Philip's work located at
http://git.wildfiregames.com/gitweb/?p=0ad.git;a=shortlog;h=refs/heads/projects/philip/pathfinder
Includes code by wraitii, sanderd17 and kanetaka.

An updated version of docs/pathfinder.pdf describing the changes in
detail will be committed ASAP.

Running update-workspaces is needed after this change.

Fixes #1756.

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.

2e7436434d warning fixes: mostly size_t vs. specialized API type and other type conversion.
added player_id_t typedef and INVALID_PLAYER, use that instead of -1.
also added sanity checks to cpu.cpp to ensure ARCH_* is correct (see
http://www.wildfiregames.com/forum/index.php?showtopic=13327&hl=)
and further predefined macros to arch.h just to be sure.
