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)

Tested by: Stan, Freagarach, mammadori
Closes #5861

25490bfec3 Improve JS Exception handling.
- 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.

Part of the SM52 migration, stage: SM45 compatible (actually SM52
incompatible, too).

ee0d204bf6 Wrap JSAutoRequest and replace usage of JSContext* with the wrapper.
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.

6f1d17c954 Stop failing if mod is broken and display invalid mods in downloader [Mod Io]
If one mod is not signed or broken in any other way, mod.io downloader
fails and does not display any mod.
The problem with unsigned mod is that its metadata are empty.

That means one cannot break mod io downloader with mods having invalid
data.

mark mod as invalid and display in list as disabled and display reason
instead description to not spam ugly error messages on screen as this is
not error by the game but of the moder
report failed signatures back to list of mods
fail if property is not set using strict mode when getting from js
check in js for undefined values

Allow to filter only valid mods.
