- 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.

SM52 essentially replaces JSRuntime with JSContext (though JSContext
itself was replaced with JSCompartment).
To prepare for this migration, rename all Runtime-related things to

ScriptInterface is now a wrapper around a JSCompartment, and thus always

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.

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.

When serialising JS objects, we keep track of any encountered object,
and serialize it only once. Any further serialisation instead stores an
ID referring to the original object (essentially an opaque pointer).
The trouble of course is to have a unique, persistent identifier for
such an object.
svn uses an ObjectIDCache, essentially a "JS Object -> ID" map (which
internally is essentially a "JS heap pointer -> ID" map).
JS, since ES15, includes a "Symbol" primitive type, which is a unique,
immutable identifier. They are also not iterable by for..in or
GetOwnPropertyName or related.
This means they can be used to store the tag directly on the object
(since it's impossible overwrite a user property).
Thanks to this, we can forgo ObjectIDCache in the serializers, and since
following D2897 it becomes unused, we can delete it, along with the
Finalization code it used.

Optimizing the memory footprint requires likely different functions

Itms came up with the same patch for the SpiderMonkey 45 update
independently.
This was SVN commit r20062.
64bit conversions (including the long ones) are not safe, because not
every number can be converted to the 2^53 JS numbers and pretending to
do so is asking for bugs.
Explicitly use the double type in the Replay menu, because std::time_t
is unspecified and some platforms like Ubuntu yakkety:i386 fail to
build, looking for long.
Double should work for the next 285 million years, becomes consistent
with SavedGame.cpp, is tested by test_ScriptConversions.cpp and doesn't
pretend to cover all 64bit numbers.
