1e8299dcdb Fix off-by-one line number in JS error reporting.
Post SM60 upgrade, CompileFunction started actually adding a line in
front of the source buffer, shifting the error reporting in the
simulation and other callers of LoadScript.
The GUI isn't affected as it uses LoadGlobalScript, which uses Evaluate
directly.

e22a915351 Add a function to query a global object, including JS classes, from C++
The latter are not properties of the global object but stored within the
global lexical environment.
This is not currently needed, but will be useful for future diffs.

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)

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.

fd8f5abd2e [SM52 2/2] Update to Spidermonkey 52 APIs.
No particularly noteworthy changes, as most complex API changes were
already supported in SM45 and done.
The addition of JSStructuredCloneData allows to remove our custom class.

Changes:
- InformalValueTypeName is back in the API, so remove our
implementation.
- Stop using JSRuntime entirely in favour of JSContext*
- 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
isn't recoverable)

Most of the patching was done by Itms.

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).

ab5616b4c4 Mass rename CxPrivate to CmptPrivate.
As part of the SM45->52 migration, a ScriptInterface becomes a wrapper
around a JSCompartment, not a JSContext, thus we ought to store private
data for the compartment and not the context.
This is a mass rename of CxPrivate to CmptPrivate to match that before
the actual changes.

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.
