c62ad8fefa Implement FromJSVal<IObject*> safely
By making all GUI proxy objects share the same class, we can easily
confirm if a given JS object is one, and from there convert to the
appropriate types.

fc60d80af1 Simplify GUI Proxy implementation & customisation.
This finishes 7c04ea0211 and 1b67a079fb.
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).

1b67a079fb Reduce duplication in JSI GUI objects implementation.
- Store the functions in an unordered_map. A no-container implementation
is doable but likely not worth the added code complexity, maybe with
C++20
- Move more things into the _impl.h
- Clear out the un-necessary friends declaration in the specific types
by moving the functions to the public interface, which makes sense.
- Fix a memory leak (JS::PersistentRootedObject weren't deleted).

This doesn't change what one needs to do to add a new type, but it does
reduce the actual code that's necessary, and makes it less error prone.

d92a2118b0 [SM78 2/2] Update to Spidermonkey 78 APIs
This ugprades 0 A.D. to the latest ESR at the moment of writing.

Mostly straighforward API changes (see meta-Bug 1633145)
- js::Class is merged with JSClass
- JSNewArrayObject becomes JS::NewArrayObject
- ArrayObject-functions are moved to a new public header Array.h
- JSMSG error messages have again been changed, requiring some tweaks.
- AutoValueArray becomes RootedBalueArray (Bug 1634435)
- 'uneval' is behind a Realm flag (Bug 1565170), but no removal is
planned in the short-term future.
- Some minor GC API changes (Bugs 1569564 and 1633405)
- Error reporting has had some tweaks, and error flags have been removed
(Bug 1620583)
- StructuredClone are now always thread-safe, simplifying an API change
introduced in SM52 (Bug 1607791)

783e77cc8d Fix f78d3ddf71 - actually speed up MP/lobby chat.
f78d3ddf71 / D1781 would fix an important source of lag... If it
actually used the code.
Also clean up some comments.

02578e46bf [SM68 2/2] Update to Spidermonkey 68 APIs
No noteworthy API changes.

Details:
- Remove UTF16 script execution since UTF8 is supported in SM68 and
going forward
- Several new headers includes are required
- Realms replace Compartments as "global holders" (see meta-Bug 1357862)
- JSRequests are removed entirely (Bug 722345), see also aae417bd29
- Trivial API updates in ProxyHandlers, ArrayBuffer, Warnings, GC
reasons, Context options, ObjectIsFunction, ValueVectors and
JSCompartment

d07f271d60 [SM60 2/2] Update to Spidermonkey 60 APIs
Two noteworthy changes:
- Proxies are update to the SM60 API, having an explicit reserved slot
and a private slot, in which the 'proxy data' and the C++ object are
stored. This fixes a debug assertion failure of SM52 (See bugs 1237504
and 1339411)
- The GC callback behaviour has changed slightly, and we should now only
look for GC_SLICE_BEGIN and GC_SLICE_END calls (Bug 1364547)

Other updates are minor:
- Bug 1339036: JSTYPE_VOID beomes JSTYPE_UNDEFINED
- Bug 1308236 - avoid ambiguous comparison by changing NULL to nullptr
- Bug 1421358, GC::reason::REFRESH_FRAME was removed. API is indicated
in jsapi.h so use that.
- Compartment behaviours update
- ClassOps changes (Bug 1389510 removed the getter/setter - 7c04ea0211 -
and bug 1370608 added one more before that so net minus one)
- Minor tests touchups again.

7c04ea0211 Make JS GUI Objects Proxy objects.
The JS-side counterparts of C++ objects are now Proxy objects, in
anticipation of SM60 changes that remove the get/set hooks entirely.
This makes semantic sense too as they are essentially phantom wrappers
around the C++ objects, with no proper JS representation.

By using different proxy handlers for different GUI object types, we can
further fix issues encountered in D2136 by defining the relevant
functions only on objects that should have them.

The main complexity with proxy handlers is that Spidermonkey assumes in
several places that they are static and data-less, so they cannot be
used directly to hold data. This diff works around that issue by storing
per-script-interface data in the CGui directly.

Further API changes in SM60 make this slightly cleaner.
