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.

ffd2219200 Don't overwrite JS error reporting by calling JS_ReportError.
Upstream spidermonkey supports JSNative error reporting by returning an
explicit failure code. This provides a full stacktrace. Calling
JS_ReportError, removed upstream, removes that stacktrace.

Instead, we should simply LOGERROR.

eafd44cfc5 Remove counterproductive lowercasing of GUI ScriptEvent names, refs #127.
a8f48ff7e0 introduced XeroXMB lowercasing of element and attribute names
as a feature.
cf9d8b9797, 4d390f501c, dda6268466 added bugfixes and TODOs because of
that.
f76d0ffdc6, 44fe226dd2 removed the XeroXMB lowercase feature.
This patch removes the lowercasing GUI bugfixes that don't fix any bug
anymore while increasing code complexity and lowering performance
(string copies).

Do not send mouse coordinates objects for events that do not relate to
the mouse.

Store event names in static const members to:
(1) improve performance, ensuring that the CStr is not reconstructed
every call,
(2) obtain compile errors when misspelling event names,
(3) allow reuse of the strings in inherited and friend classes.
