- With modules JavaScript code can be split up into multiple files. We
already implemented such a mechanism (`Engine.LoadLibrary`) in
multiple parts of the engine. The advantage of using modules is
that it's standart (JS-devs are familiar with it) and it doesn't
has to be implemented multiple times.
Note that `Engine.LoadLibrary` loads all files in a directory
while the new `import` only loads one file.
- With modules seemingly global variables are local to that
script/module. We already implemented such a mechanism
(`ScriptInterface::LoadScript`).

This is unused and makes the function twice as slow as it needs to be.
Differential Revision: https://code.wildfiregames.com/D5015
This was SVN commit r27697.
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.

This splits off the object-related functions, such as

It also puts the definitions in the header itself, which might end up

This removes the boost-CPP function wrappers entirely, in favour of pure
templated code in FunctionWrapper.h
The Call* functions were already heavily templated, so there is nothing
really new here. I just use tag dispatch to reduce the number of
overloads slightly.
The new functions do not need the script interface, only the script
request.

- Several passthrough functions are simply removed in favour of calling

- Make use of ScriptRequest/ScriptInterface capabilities where
relevant.
- Make JSI_* headers only expose necessary functions, lightening them
considerably and reducing duplication
- Reuse namespaces in JSI_* implementations directly, reducing visual

The new methods:
- aren't included in ScriptInterface.h directly, lightening that header
- don't use boost CPP
- don't need argument types or number or constness to be specified
- can work with object methods somewhat transparently
- support optional cmptPrivate (allowing removal of many UNUSED macro)
- support optional const ScriptRequest&, which is safer.

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

No particularly noteworthy changes, as most complex API changes were

- JSPropertyDescriptor is renamed.
- CompartmentOptions are tweaked slightly (no functional changes)
- JS::Construct - API update.
- JSClass split - API update.
- A js.msg error message was removed, so we had to use a different one.
- Tests fix: fix comparison of union instances
- Disable warning in spidermonkey Vector.h
- Update error reporting to SM52 (minor API updates)
- Ignore warnings about unused return values (would come from OOM, which

- Check for pending exceptions after function calls and script
executions.
- Call LOGERROR instead of JS_ReportError when there is a conversion
error in FromJSVal, since that can only be called from C++ (where JS
errors don't really make sense). Instead, C++ callers of FromJSVal
should handle the failure and, themselves, either report an error or
simply do something else.
- Wrap JS_ReportError since that makes updating it later easier.
This isn't a systematical fix since ToJSVal also ought return a boolean
for failures, and we probably should trigger errors instead of warnings
on 'implicit' conversions, rather a preparation diff.

As part of the SM45->52 migration, a ScriptInterface becomes a wrapper

This was SVN commit r24177.
JSAutoRequest is required before calling into most JSAPI methods, for GC
reasons.
Calling it is required and fragile as one must not forget.
Further, SM52 and later make manipulating JSContext* dangerous as that
can cross Compartment(Realm in SM68) barriers (and ScriptInterface now
matches a Compartment).
The solution to both problems is to avoid using JSContext* in 0 A.D.
itself. To achieve this, a Request class is introduced, and must be used
to access a JSContext* from a scriptInterface. Further, Request is
passed to other ScriptInterface functions isntead of JSContext*, making
it obvious that the caller has already called it, reducing errors and
redundant JSAutoRequest calls.
Only JSNative functions now get a naked JSContext* without protection,
but the likelihood of forgetting a request is lower since many
ScriptInterface functions now expect it.
JSContext* is directly passed to JSAPI functions only.
