When calling `Engine.PushGuiPage` a promise is returned. The promise is
settled when the "child" page is closed. That allows to `await` it
inside `async` functions.
Previously the callback was run right inside the call to
`Engine.PopGuiPage`. Now the continuation of the promise is called at
the end of the "tick".
This won't help performance. It will more likely make things worse.
Since gui pages aren't opened or closed that frequently, it doesn't
matter that much.
Refs: 86c151ebaa
For the engine side:
The promise is stored in the `CGUIManager::SGUIPage` (like previously
the callback). When the promise is fulfilled it enqueues a callback in
the `JobQueue` of the `JSContext`.

Summary:
Most of the times the callback stores a reference to a variable in scope
where the `Future` is in. When the scope is left the reference get's
dangling. `CancelOrWait` is called in multiple places (mostly
destructors) to ensure the callback isn't executed anymore.
This patch deduplicates thous calls to `CancelOrWait`.

Since 1bccfef6fb the `CSimulation2` uses the `std::shared_ptr` only in
the constructor and stores a `ScriptContext&` (inside it's members).
That's a bit dangerous: A caller might think `CSimulation2` takes
ownership of the `ScriptContext`.
With this commit the caller has to pass an `ScriptContext&` to the
constructor.

Two changes to the vertex pathfinder that should generally improve
performance:
- Sort unaligned edges by distance like we did aligned edges. This
isn't very scientific, but the idea is generally sound, and empirically
it seems to do OK.
- Relax the optimality by using a weighted heuristic, with weight 4/3
or 5/3 depending on the number of obstacles around. In the worst cases,
A* will return paths that are this many times less optimal, but search
should be faster in general (and sometimes much faster).
Both of these optimisations might increase the constant-cost slightly,
but should decrease the worst-case runtimes.

Following the AI unthreading in 4df03ed2d2 / D3769, structured clones

This is much faster, about 10-15% wall time on an AI 1v1 profile.
This also potentially reduces memory fragmentation and GC needs, as
writing clones allocated a lot of data.

CmpPosition::TurnStart checks whether the territory changed underneath
each entityevery turn. The only user of this is TerritoryDecay
(structures, for the most part). It is rather inefficient to have this
done for all entities.
The simplest solution is to listen to position-changed messages in
TerritoryDecay instead. This should hardly ever happen in vanilla 0
A.D., except in Atlas, so it's basically free.

Follows 8eecc39e71.
Piping the autostart through a GUI page is easy but requires using the
GUI in non-visual mode, which is problematic since it's not initialized.
The GUI is not needed, only its ability to load scripts, so this diff
fixes the problem by adding an 'entrypoint' script in the new
`autostart` folder that gets called with this unique ability, setting
things up properly. The mod mod gets a placeholder.
Other changes:
- Fix some issues with networked autostart:
- Players were not assigned slots.
- The host didn't actually wait for other players.
- Move gamesettings from `gui/gamesettings/` to `gamesettings/`. This
moves attributes as well.
- Move autostart files from `gui/autostart/` to ` autostart/`. Note that
`gui/autostart/` still exists as it's used in the tutorial button from
the main menu.
- Rename the JSI_VFS functions to be explicitly about their function:
the ability to write and the potential restricted folders.
- Don't require `autostart` when using `--autostart-client` in
non-visual mode.
Starting the autostart client/host has poor UX in some situations, but
improving that feature is beyond the scope of this diff.
Suggestions for future work:
- Some files in gui/common should probably be moved elsewhere
- Template loading code is duplicated
- The gamesetup code still needs work for proper UI/logic separation.

This makes it possible to make units heavier, which both push more & get
pushed less by other units.
In particular, the diff does it for siege units & elephants.
This improves movement for these units in crowd situation, since they
will now basically not move when other regular units push into them.

This is a paradigm change for AI computation.
Historically, the AI was intended to be run in a separate thread from
the simulation. The idea was that slow AI wouldn't stop the renderer
from being smooth.
In that original design, the AI received a copy of the game world and
used that to run its logic. This meant the simulation could safely do
whatever it wanted in the meantime. This copy was done via AIProxy &
AIInterface.
This design ended up having significant flaws:
- The copying impacts the simulation negatively, particularly because
AIProxy subscribes to a lot of messages (sometimes sent exclusively to
it). This time cannot be threaded, and impacts MP games without AIs.
- Copying the data is increasingly difficult. Modifiers are a headache,
LOS is not implemented. Lots of logic is duplicated.
The intended benefits of the design also failed to realise somewhat:
- The AI was never threaded, and in fact, it is probably better to try
and thread Sim + AI from the renderer than just the AI, at which point
threading the AI specifically brings little benefit.
The new design is much simpler and straighforward, but this has some
side-effects:
- The AI can now change the simulation. This can be used for cheating,
or possibly for a tutorial AI.
- The AI runs in the same GC zone as the simulation, which may lead to
more frequent Sim GCs (but overall we might expect a reduction in
temporary objects).
- The AI state was essentially cached, so replacing some functions with
Engine.QueryInterface might be slower. The tradeoff should be balanced
by lower AIProxy computation times.
Future work:
- Threading some specific AI tasks could still be worthwhile, but should
be done in specific worker threads, allowed to run over several turns if
needed.
Technical note: the AI 'global' is in its own Realm, which means name
collisions with the same are not possible.
Other notes:
- The RL Interface uses the AI Interface and thus will gradually lose
some data there. Given that the RL Interface can now request data
however, this should be dine.

The UnitManager already lists all units, so we do not need to go through
the visual actor of entities to update them. This is faster and
decouples simulation & graphics code slightly.
Further, the simulation does not need to know about texture changes (see
also 410d2e883a), so remove those calls in Atlas.

This was SVN commit r26269.
The main change is the introduction of a 'pushing pressure' counter on
units. This counter increases when units get pushed around, and
decreases over time. In essence, units under high pressure move slower &
are harder to push around.
The major effect is that units can now get bogged down when very dense
groups start colliding. This makes movement more realistic, makes unit
movement more 'chokepointy', and generally improves the mathematical
soundness of the system (lower values are easier to handle for our 200ms
turns).
Other changes:
- The logic to detect units crossing each other's path has been
reworked. Units that run towards each other should not more obviously
avoid each other.
- New parameters: 'Spread' is a measure of how strong the pushing effect
is based on distance. With the current settings, static-pushing is
rather 'on/off', whereas moving-pushing is more gradual (and thus the
max influence distance was increased when moving).
- Default values have been tweaked for lower overlap.
- Units only looked at other units within their grid region. This led to
overlap near grid-borders. Units now look at neighboring grid elements,
which largely removes this issue. While this may be slower, the
performance of pushing was largely negligible before, so it is unlikely
to become a main cause of lag (and overlap was generally disliked by
players).
- Units no longer orient in the direction of pushing, but instead keep
facing their target. This can look slightly odd under very heavy pushing
forces, but vastly improves behaviour of very slow units such as rams
(since they spend much less time turning around). As a side-effect,
clean up angle code following acc780bcbb .
Engine changes:
- Add a debug rendering mode at compile-time to help understand what is
happening.
- Make it possible to constexpr initialise fractional fixed numbers by
using FromFraction
