eb7940b418 Silence warnings about unused result.
Introduce a DISCARD macro to ignore the warn_unused_result attribute
used by Spidermonkey, and reuse it elsewhere.

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).

ab5616b4c4 Mass rename CxPrivate to CmptPrivate.
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.

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.

1a66f510d0 Use const T& for parameters of some types in script-exposed native functions
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.

5f86beea6f Replace HandleWrapper and avoid repoint function
JS::Handle<T>::repoint gets removed with SpiderMonkey 38, so the
existing solution has to be replaced. The new approach should also be a
bit clearer. Named Return Value Optimization (NRVO) should avoid a
superfluous temporary for the return value in the generic template
function implementation of AssignOrFromJSVal.

c02a7e1a7b SpiderMonkey 31 upgrade
This upgrade also introduces exact stack rooting (see to the wiki:
JSRootingGuide) and fixes problems with moving GC. This allows us to
enable generational garbage collection (GGC).
Measurements a few months ago have shown a performance improvement of a
non-visual replay of around 13.5%. This probably varies quite a bit, but
it should be somewhere between 5-20%. Memory usage has also been
improved. Check the forum thread for details.

Thanks to everyone from the team who helped with this directly or
indirectly (review, finding and fixing issues, the required C++11
upgrade, the new autobuilder etc.)! Also thanks to the SpiderMonkey
developers who helped on the #jsapi channel or elsewhere!

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.

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.

cfa59fc4e1 Changes our JSNative functions to use JS::CallReceiver/JS::CallArgs.
This is the new way for working with arguments in JSNative functions.
JS_THIS_VALUE, JS_ARGV, JS_SET_RVAL and direct access to vp or argc are
deprecated and will probably be removed in future versions of
SpiderMonkey.
CallArgs also takes care of proper rooting and you can get the values as
Handles or MutableHandles. The interface changes a little bit for ESR
31, but commiting this now still makes it easier and the changes shout
be straigtforward (search and replace more or less).

4663ac0fe7 split debug_assert into ENSURE and ASSERT as discussed in a previous meeting.
the old debug_assert always ran and tested the expression, which slows
down release builds. wrapping them in #ifndef NDEBUG is clumsy. the new
ASSERT behaves like assert and ENSURE like the old debug_assert. Let's
change any time-critical but not-super-important ENSURE to ASSERT to
speed up release builds. (already done in bits.h and unique_range.h)
