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.

Completes work starting in D2313 / a33fd55e81:
- Make C++ mistakes where values can be changed without messages being
sent easier to notice / harder to do.
- Make the IGUISetting interface more flexible, allowing custom settings
implementing their own logic. This is used to clean up hotkey code
introduced in 33af6da5e1.
Side effects:
- FromJSVal_Vector clears the vector being passed in. I have some vague
memory of not doing that in D24 / 2bae30c454 as an optimisation, but it
seems more like a footgun to me.
- Most usage of SetSettingFromString is replaced by direct method calls,
as we can generally cast to the proper GUI object type. Where we can't,
it is kept as a poor's man virtual dispatch.
- It moves a few member variables elsewhere, e.g. TextOwner now gets its
own member variable settings.

GUI Proxy objects are now easier to specialize, code duplication is
reduced, code is made safer.
In details:
- the proxy private is always the IGUIObject* pointer
- the private data is accessed through a safer wrapper
- CreateJSObject returns an opaque type to allow easier extension &
prevent errors.
- The implementation of CreateJSObject is moved near the GUI Proxy
template instantiation, and both are wrapped in a convenient macro (this
makes it so that if you use the macro, you can't forget to overload the
method, and vice-versa).
- The common IGUIObject JS interface no longer needs to be repeated.
- All specialisations are again put in the same file, for improved
compile-time & clarity, given there are so few lines now.
- While at it, implement toSource which makes it possible to `uneval`
components (does the same as toString though).

This is the same commit as 4bb31f084e, reverted in 5d1899785a. Noted
issues were fixed.
Partial revert/fix of 2f19cf86d3 and 2567fee329.
Before this diff, it was possible for a mod containing a cache/ or a
config/ folder to get written to incorrectly.
The issue is VFS can map multiple directories to one 'virtual' path, for
reading mods. However, writing data is problematic: which path to
choose?
The only viable solution is to use a path relative to the highest
priority directory encountered in the VFS path, or write paths could be
'hijacked' by lower-priority mods.
This fixes these issues by:
- Adding a new lookup mode ('Real-path') that explicitly picks the real
path relative to the highest-priority subdirectory in the VFS Path.
- Preventing overwriting a real directory with a lower priority one in
general.
- Revert c0c8132dd4's GetRealPath change, re-introducing the function as
GetOriginalPath.
This also cleans up some duplication that led to empty mod folders in
the user mod path, and cleans up loading the 'user' mod.
It also makes it explicit that a directory must be passed to Mount().
Note that the new 'realpath' lookup can still be somewhat complex with
many mount points at various hierarchy levels, but it is at least
predictable/deterministic without having to be careful about populating
order.
