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.

This was SVN commit r17696.

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!

5c07a25ddc More exact stack rooting (CallFunction object).
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.

31f9ca9ebf Implements CallFunction with JS::MutableHandle<T> return type.
Changes the CallFunction implementation to use macros because otherwise
we'd have to write twice as many functions manually.
Adapts GetSavedGameData to use the new function template. Additional
callers will be changed in future commits.

52f4cda439 Changes ToJSVal to take JS::MutableHandleValue instead of JS::Value&.
JS::MutableHandleValue is similar to JS::HandleValue, but the whole
JS::Value it points to can be replaced.
This change is needed for support of exact stack rooting and moving GC.
Contains a few other trivial API adjustments and style improvements too.

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).

e9e05f4efc Second (main) commit for the SpiderMonkey upgrade.
This commit contains all the required changes to our source files and
build scripts (hopefully).
A next commit will remove the old stuff of SpiderMonkey 1.8.5.

Spcial thanks to:
 - H4writer who helped a lot mainly with the performance issues we
had/have, but also with other problems or questions.
 - Leper for the review.
 - Historic_bruno for implementing the build scripts on Mac OS X and
testing on the Mac.
 - The people from the #jsapi channel and from
mozilla.dev.tech.js-engine who answered a lot of questions and helped
solving problems.
 - All the other people who helped

4b1297b328 Removes g_ScriptingHost and implements global to compartment 1 to 1 relation.
Each GUI Page gets its own compartment and all ScriptInterfaces in the
same thread should now use the same JS Runtime.
This is required for the SpiderMonkey upgrade.
Check the ticket for details.

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)
