f189172db6 UnitMotion hack to fix units being stuck near corners.
I think there is a small mismatch between CheckMovement & the vertex
pathfinder when computing passability because one is ray-based and the
other just uses edges. However, it's out of my reach to fix it for now.
This can lead to units being stuck near building edges occasionally.
This introduces an un-intrusive recovery strategy (aka a hack) in
HandleObstructedMove that should get the units unstuck.

Should fix #6114 (to a sufficient extent anyways)

83703992c9 Fix speed glitch
Introduced in 40cbde1925
MoveToFormationOffset may be called after the formation controller is
reset, leading to issues. It seems best to trust only
SetMemberOfFormation.

This causes the speed glitch experienced by wow & Valihrant.

40cbde1925 Further Pushing tweaks: more customisable, longer ranges.
This overall decreases the deathball effect from units walking to each
other a bit.
- Fix formations - this cleans up a UnitMotion hack for formations,
making it possible to increase pushing ranges without breaking closely
knit formations like testudo.
- Make MINIMAL_PUSHING and the MOVE_EXTENSION configurable, and add a
STATIC_EXTENSION as well.
- Increase the pushing range significantly, making units sparser.

3745940de8 Fix OOS in unit motion
Fixes 592453c62f
wasObstructed and wentStraight are not reset when Move() isn't called,
but PostMove may still be called (if the unit was pushed). This will
OOS.

bb49fbe793 Further reduce usage of TERRAIN_TILE_SIZE in non-terrain components
TERRAIN_TILE_SIZE is now only used in relevant places in the simulation.
This also makes it mostly possible to use CFixed in constexpr contexts.

35ed55cfd6 ParamNode: switch to utf8, ToXML -> ToXMLString, test tweak, PCH tweak
This changes ParamNode to use UTF8 values internally (XMB files are UTF8
since cb9d0733ef).
This removes the need for a lot of conversions, speeding things up and
allows cleaning up the validator interface & a few other callsites.
ConstructJSVal could be a tad slower because of UTF8->16 conversions
within Spidermonkey; but the difference is unlikely to be noticeable in
practica.

Also:
- Changes `ToXML` to `ToXMLString` for clarity.
- Add a simple "op" test & show a particular behaviour of merge nodes
that I intend to change somewhat in D3830.
- Remove Component.h from simulation2 PCH - brought in too much.

52e8a0c5fb Fix chasing after Motion Manager & Pushing.
The motion manager introduced in bae258f9a1 makes 'chasing' (e.g. an
entity targeting another entity, which also applies to fleeing)
behaviour symmetrical: both units see the initial state instead of it
being ID-dependent.
This allows removing hacks introduced in 6a66fb8205 (and refined in
7b88b1a0f9).

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).

f6a2d6da63 Fix degenerate case in UnitMotion resulting in lag.
9d82ae15af introduced logic to extend the search range of the short
pathfinder in some situations. This extension was unbounded, resulting
occasionally in search domains several hundred meters wide, and path
computation that can take several seconds.

eac613b7bf Enforce tight coupling of CCmpUnitMotion/CCmpUnitMotionManager
bae258f9a1 implemented CCmpUnitMotionManager, which handles motion for
CCmpUnitMotion (as distinct from ICmpUnitMotion, the interface).
The tight coupling between these two components was awkward at the
interface level, leaking underlying implementation details.

This diff makes CmpUnitMotionManager explicitly manage CmpUnitMotion,
instead of any implementation of ICmpUnitMotion, and moves files around
as requir
ed.
This:
- Makes it impossible to accidentally try to have the wrong
IID_UnitMotion managed by the UnitMotionManager.
- Allows devirtualising the calls from the manager to UnitMotion itself
(and inlining, as they are compiled in the same TU).
- Cleans up the manager interface - MotionState is now part of
CCmpUnitMotionManager.
- Cleans up ICmpUnitMotion interface - no need to provide a private
interface for the manager.
