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

This was SVN commit r24261.
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.

Differential Revision: https://code.wildfiregames.com/D3095
This was SVN commit r24203.
- 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.

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.

This was SVN commit r24176.
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.

The script interface has code to serialize/deserialize JS objects with a
user-defined prototype. That code is usable in the AI, but currently
unused (and there are no plans to use it in the long run).
Removing it allows removing more code down the line, which helps with
the SM45-52 migration.

Following 809f297707, this decouples the hierarchical pathfinder and the
long pathfinder. The long pathfinder was the class owning the
hierarchical pathfinder, which didn't particularly make sense and
resulted in some interface awkwardness.
At the moment, the long pathfinder still needs to hierarchical
pathfinder to compute paths (to make sure they are reachable).

This was SVN commit r18760.
Using references matches the C++ coding style better and should improve
performance a bit in theory. It avoids 2 copies of T in case of the
functions registered with RegisterFunction (mainy used in the GUI). It
should also avoid one or two copies in case of
DEFINE_INTERFACE_METHOD_X, which is used in the simulation, but I
haven't bothered to count it there exactly.
It is now predefined which types have to be passed by const reference
and which are passed by value. Note that references can't be used as
out-parameters (to return multiple values to JS). This hasn't worked
before either and probably never will.
