ScriptInterface is now a wrapper around a JSCompartment, and thus always
has a well-defined global.
The error reporter is moved to ScriptRuntime in anticipation of that
handling JSContext in a later diff.

This was SVN commit r24180.
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.

This avoids vswprintf failures when printing non-ASCII char* strings
from CLogger into the console.
Also convert ScriptInterface::ToString to return UTF-8, to avoid some
utf8_from_wstring calls.
Also remove some unused and redundant CConsole functions.
This was SVN commit r16333.
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.

I had to change a few other functions to take JS::MutableHandleValue
because JS::Stringify takes a JS::MutableHandleValue as input parameter.
That seems a bit strange because it should not change that value.
I assume it has historical reasons.

This was SVN commit r15605.
Changes CallFunction and CallFunctionVoid to use a HandleValue as object
parameter. Also changes some JS serialization/deserialization functions
to only support the JSAPI rooted types (drop support for CScriptVal and
CScriptValRooted there). Some other functions got changed too because
they were closely related.

* 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.

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).

This commit contains all the required changes to our source files and

A next commit will remove the old stuff of SpiderMonkey 1.8.5.
