Introduce CanEverReachTarget in the Attack component to check whether
a target is geometrically reachable at all, accounting for height
offsets and turreted units inside buildings.
For non-parabolic attacks (e.g. melee), a simple 3D distance check
from the closest approach point is used.
For parabolic attacks (e.g. ranged), the parabolic range formula
is used to determine if the height difference is surmountable
from the closest horizontal distance to the target.
Add GetClosestApproachDistanceToTurretPoint to TurretHolder
to estimate the minimum horizontal distance to a turret point,
using its local offset and the holder's obstruction size.
Passable buildings are not considered obstacles.
Fixes units on the ground trying to attack unreachable units on walls
or towers when the projectile's arc cannot reach the required height.
It was previously stored at the end of the array of per-player flags and
set by calling SetLosRevealWholeMap with the player ID -1. However, ever
since the introduction of observer mode in 883f307b40, -1 is the player
ID of observers everywhere else including for GetLosRevealWhole:
GetLosRevealWhole(-1) always returns true in order to reveal the map to
observers, however, the cinema manager, for example, called it meaning
to find out whether the whole map is revealed to all players.
To fix this and avoid confusion about this in the future, this patch
splits this flag from the per-player flag array and introduces new
functions to set and retrieve it.
This name is more descriptive.
And the plan is to split off the extra player value of the vector into
an own flag in the future, and LosRevealAllForAll would have been a poor
name for that.
Avoid cases of filenames
Update years in terms and other legal(ish) documents
Don't update years in license headers, since change is not meaningful
Will add linter rule in seperate commit
Happy recompiling everyone!

This was SVN commit r27786.
The main benefits are more convenient code in the component interfaces
TU and no limit on the # of arguments that can be passed.

This was SVN commit r25350.
Introduce a LOS_TILE_SIZE, to replace usage of TERRITORY_TILE_SIZE in
the LOS code.
This makes it possible to change the resolution of LOS/Terrain without
affecting the other component.
Additional refactoring:
- LosTile has been renamed LosRegion (it's more comparable to the
hierarchical pathfinder regions/spatial subdivisions)
- LosState explicitly refers to "los vertices" instead of terrain
vertices.

This was SVN commit r24980.
Units sometimes ignored targets that entered their LoS. The cause is
d0fc8ff67d: range queries returned units farther away, and those units
might actually be out of range if distance is computed center-to-center,
which both UnitAI and LOS do. This meant that code relying on range
query updates was possibly broken, and indeed units missed things (see
ticket).
This introduces a boolean to switch between pre-d0fc8ff67d behaviour
(entity-as-point, center-to-center range queries) and post-d0fc8ff67d
(entities-as-circumscribing-circle, edge-to-edge range queries).
The former is used for UnitAI (where the new behaviour bugged), auras
(where varying structure sizes made it awkward) and build
restrictions(which simply did not really need it).
Reverts 7f1ee23d88, 050c5401b1 (with the exception of the iber monument
footprint), and the template changes in d0fc8ff67d itself.
It also reduces alertRaiser ranges slightly, this was missed in the
original diff.
#3381 is not reopened as BuildingAI still uses the new range queries.

Range manager has several `std::vector` for fixed-size arrays and 2D
grids. By using proper data structures, the code readability is
improved.
This also moves around the LosVisibility enum.

Units can be stuck in gather states when the target ought to be
collectable from, but it's actually unreachable.
A new FINDINGNEWTARGET intermediate state for GATHER will try and find a
new, different target to collect from. This should generally improve the
behaviour (perfect reachability checks would be required to completely
fix it).
Use this also when the target is knowably unreachable / uncollectible.

This improves performance quite a lot because it avoids a huge number of
