0f60bf3a97 Split off Object-related functions from ScriptInterface
Follows 34b1920e7b.

This splits off the object-related functions, such as
[Set/Get/Has]Property, CreateObject, CreateArray, FreezeObject.

It also puts the definitions in the header itself, which might end up
with faster code here & there, though perhaps slower compilation time
(somewhat doubtful since we already included most things anyways).

61e0aef0b4 Split JS conversions from ScriptInterface.
All ToJSVal/FromJSVal definitions are put in a separate header.
Remove AssignOr[To/From]JSVal duplication.

The functions were already static so this is rather straightforward.

d46a417748 Replace ScriptInterface::Call* with new ScriptFunction functions
Finishes work started in f3aedf88a6.
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.

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.

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).

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.

dcf5a2667f CLogger: Use cppformat instead of sys_vswprintf.
sys_vswprintf relies on platform-specific printf implementations, which
vary widely between platforms (in handling of truncation, return values,
use of %s/%S/%hs/%ls for mixing char and wchar_t strings, etc) and are
therefore a pain.

Use cppformat's fmt::sprintf instead, which has very similar syntax to
sprintf but is more C++ish and is portable.

Also, wchar_t is stupid, so use char* strings (which are expected to be
UTF-8) in CLogger. This creates a bit of a pain with changing all
callers to convert to char* strings, but that's their fault for not
using UTF-8 already.

169174824f Exact stack rooting for ScriptInterface::ToString.
I had to change a few other functions to take JS::MutableHandleValue

e818b08344 Better support for SpiderMonkey rooted types in the ScriptInterface.
* Adds additional overloads/specializations which are required when
passing JS::Handle<T>/JS::MutableHandle<T> types to different functions.
* Replaces GetPropertyJS with a GetProperty specialization.
* Allows us to avoid the implementation of ToJSVal specializations for
JS::Value and JS::HandleValue. Such conversions should only happen if
there's no way around it and if you are aware of it.
* Adds test to make sure that all potentially required specializations
with custom implementations are instantiated. This should help prevent
introducing bugs in temporarily unused code.

7acdde5c86 Changes tests to use global g_ScriptRuntime instead of creating a new JSRuntime for each test.
The tests crashed on my Debian systems but not on my Ubuntu system.
The crash happened in line 142 of SpiderMonkey's ThreadLocal.h.

I know that I had to use a workarounnd for contexts to avoid destroying
the context that was created first. I also had in mind that in newer
versions a JS_Init function got introduced which presumably solves this
kind of issues.
Based on this experience I assumed runtimes could have a similar problem
and this patch indeed fixes the issues.
Unfortunately the correct usage of JSRuntimes in that regard is not
documented.
There's only a rater misterious comment in JSAPI.h which hasn't been
cleared up so far and is most likely completely outdated
(https://bugzilla.mozilla.org/show_bug.cgi?id=992641).
