592453c62f Add a simple 'pushing' logic to unit motion to improve movement.
This implements a form of crowd movement that I've generally called
'unit pushing' in the last few years.
Essentially, any two units will push each other away when they're too
close. This makes it possible to ignore unit-unit obstructions, and thus
makes movement much smoother in crowds.
This first iteration of this system only allows pushing between idle
units and between moving units (i.e. a moving unit does not affect an
idle one).
This is because the unitMotion logic to detect it is stuck & needs to
use the pathfinders starts breaking: units can fail to move because they
are pushed away from their intended movement, and the current logic
fails to handle this gracefully.
Thankfully, the most value of this patch in terms of player experience
is found in the improvements to group movements and shuttling.

Other impacts:
- As the short pathfinder is called less often, we can increase the
starting search range & reduce the # of max turns, both improving
collision recovery.
- The performance of idle units is slightly worsened, as they must be
checked for idle-idle collisions. If needed a 'sleeping' system, as used
in physics engine, could be implemented.
- In general, however, expect slight performance improvements, as fewer
short paths are computed.
- Gathering efficiency should increase slightly, since shuttling times
are likely reduced slightly.
- As a sanity change to improve some edge cases (units that say they're
moving, i.e. pushable, but don't actually move), the 'going straight'
logic is turned off if a short path has been computed. This requires a
few cascading changes to work correctly.

Technical notes:
- To reduce the cost of the n^2 comparisons that pushing requires, units
are only compared within a small square on a grid which is lazily
reconstructed each turn. The overhead seems rather small, and this is
much simpler than keeping an up-to-date grid.
- The design is intended to be parallelisable if needed someday.
- The pathfinder's CheckMovement ignores moving units in UnitMotion, as
that is now the spec. Idle units are not ignored, which is required for
the 'collision' detection to work correctly (see above).

Refs #3442 (not fixed - idle units are not pushed by moving units).
Fixes #5084 (the overlap can still happen, but units will push each
other away).

6a66fb8205 Chasing fix - ignore the target's obstruction to avoid colliding with it.
Units movement is currently "all or nothing". This means that a chasing
entity that moves fast enough is likely to collide with its target, if
the latter is moving also. This means that it might fail to get in range
if the max range is smaller than the movement speed over a turn.
This happens to be very much the case in MP, as cavalry range is 4,
melee cav speed is ~20 and turns are 500ms.

This problem depends on which unit moves first (i.e. which unit is
lowest-ID).

To fix this, ignore the obstruction of the target, if it is moving, when
moving. This however means sometimes chasers will 'overshoot' and block
their target pathing, making the chase easier than it probably should
be.
Fleeing units don't suffer from this problem since they also ignore
their target (and their code handles it).

This new problem introduced in this diff is heavily dependent on the
exact speeds and ranges at play, and a further diff will improve the
situation to acceptable levels.

GUIObjectBase is made a IGUIObject* to avoid including those headers
un-necessarily. Subsequent diffs ought to clean up the various of

Also:
- Add standard C and C++ headers (mostly cstring for memcpy, string and
vector) where needed.
- Swap out some includes for forward declarations
- Clean up un-necessary boost includes in precompiled and other headers.
- Clean up precompiled headers, including fewer things.
- Move ACPI to the windows-specific folder as it's included there only

f42d97c6f3 Fix some animals "roaming" state not working correctly (units seem stuck in place)
Due to an issue in 4a15cc3b9f, animals incorrectly tried going towards
the roaming point instead of away from it.

With that fixed, MovementUpdate still did not trigger as the min and max
range were the same.
Use -1 as max range (= infinite) instead since we want to move
arbitrarily away.

Having an infinite max range was broken in c219ee54b2, this
re-implements that.

Further, other calls with equal min and max range have been changed
likewise.

This does not entirely fix whales, which run in other problems because
of their large roaming range.

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.

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
