44aef27b78 Adapt unitMotion to edge-edge distance checks.
D981/c219ee54b2 changed IsInXChecks to use edge-to-edge distance instead
of centre-to-edge, which broke UnitMotion's min-range movement, which
assumed distance to the center.

Since units are represented as squares, the diagonal point may be closer
to the target than the "real" clearance by a factor √2, so the delta
between minimum range and maximum range should be at least `(√2 - 1) *
clearance` to be safe in all situations (this is generally not a problem
for regular units which have a clearance of 0.8, but could be one for
catapults or elephants).

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.

795e414663 Hierarchical pathfinder: Speed up edge update
Speed up edge update by being clever, only updating dirty tiles instead
of everything (effectively doing to "TODO be clever" here).

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.

75d0c56070 Don't crash when calling the profiler from a 'non-main' thread
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.

d3de36527d Hierarchical pathfinder: fix an issue with regions and some touch-ups
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.

6aa99d762f Add a new spatial subdivision, based on an old patch by wraitii.
This subdivision is faster but less precise, so range queries get more
entities and are a bit slower (up to 1ms approx.), but the overall gain
on a simulation update is always positive and can reach 10ms per frame.

For now, this new subdivision is only used by the range manager,
integrating it in the obstruction manager might be sensible.

c02a7e1a7b SpiderMonkey 31 upgrade
This upgrade also introduces exact stack rooting (see to the wiki:
JSRootingGuide) and fixes problems with moving GC. This allows us to
enable generational garbage collection (GGC).
Measurements a few months ago have shown a performance improvement of a
non-visual replay of around 13.5%. This probably varies quite a bit, but
it should be somewhere between 5-20%. Memory usage has also been
improved. Check the forum thread for details.

Thanks to everyone from the team who helped with this directly or
indirectly (review, finding and fixing issues, the required C++11
upgrade, the new autobuilder etc.)! Also thanks to the SpiderMonkey
developers who helped on the #jsapi channel or elsewhere!

8441a3f8d6 Fix compilation failure with GCC and C++98/03.
Local types shall not be used as a template argument. So move it
to a higher scope. This restriction was lifted in C++11, so we
might want to change this back when we switch to that.

8e30410109 Improve PickEntitiesAtPoint
First, do a ray intersection test with the bounding-sphere for all
entities on the map and then check the more detailed selection shape for
the remaining candidates. Do checks that require component lookups after
the ray intersection tests because these are relatively expensive.
The old method for figuring out which entities are below the mouse
cursor was incorrect because it does a 2D check to filter out the first
candidates which can lead to incorrect results with lower camera angles
and high buildings or buildings with a large footprint. Such problems
were avoided with quite a large radius for this 2D test and resulted in
a large number of candiate entities after this first test (200-500).
Also rename PickEntitiesAtPoint to PickEntityAtPoint and make it return
only one (the closest) match.

I've tested performance with the tracelogger by starting a map and then
moving the mouse in circles for one minute. The results were relatively
stable. I've compared the total time percentage of input.js:836, which
spends nearly all of the time in PickEntityAtPoint.
Ardennes Forest - Normal size:       Original: 41.46%    Patched: 31.6%
Ardennes Forest - Giant size:        Original: 40.59%    Patched: 51.55%

As we see, it's faster on normal map sizes but slower on giant maps with
a lot of entities.
This approach can be further improved with some kind of spatial
subdivision for the culling (like an octree), which would help the unit
renderer too. This way it should be possible to make it faster (and
still correct) on all map sizes and with a large total numbers of
entities.
