Speed up edge update by being clever, only updating dirty tiles instead
of everything (effectively doing to "TODO be clever" here).
This is a substantial speed improvement when an update is necessary.

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).

Motive behind the change: calls to Profile() currently crash unless they
are triggered from the main thread, but it's somewhat difficult to know
that from the code. It makes more sense to silently ignore those
particularly so we can easily have the same code be threaded or not.
This also removes a few profiling calls that don't make much sense.

This was SVN commit r22248.
FindPassableRegions intends to return all passable regions in a chunk,
but did not as it used the number of regions in that chunk. In fact,
regions can have individual IDs higher than the number of regions (as
shown by the test), therefore FindPassableRegions might miss some.
This only affected the JPS pathfinder, when starting on an impassable
cell, which called FindNearestPassableNavcell with then possibly
returned a sub-optimal navcell. This is a limited impact but upcoming
patches will rely on that function more.
Fixed using a vector to store IDs, which also makes for-range loops
usable.

Use at() over find() as it makes the code neater and the performance
impact is negligible.
This forces an algorithm change in FindReachableRegions as the key
accessed is not guaranteed to exist.

This was SVN commit r22210.
By adding a custom function in Grid, the code gets vectorised on both
gcc and clang, resulting in much faster code and faster update times,
sometimes substantially (on giant maps or when few chunks must be
updated).

Remove some useless check and a useless reverse loop, and add a flag to
prevent redundant checks.

This was SVN commit r18011.
Change the way the long-range pathfinder rasterisation works slightly so
that we have a better compatibility with the short-range pathfinder.
Should fix the "stuck units" issues, though I am not sure so I am not
marking them as fixed so far. Refs #3471, #3505, and possibly #3292.
Caveat: I am now using clearance of 0.8 for "default" class, which might
have side-effects: please report anything weird.
Also fix leftover style issues.
This was SVN commit r17161.
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.
