This ugprades 0 A.D. to the latest ESR at the moment of writing. Mostly straighforward API changes (see meta-Bug 1633145) - js::Class is merged with JSClass - JSNewArrayObject becomes JS::NewArrayObject - ArrayObject-functions are moved to a new public header Array.h - JSMSG error messages have again been changed, requiring some tweaks. - AutoValueArray becomes RootedBalueArray (Bug 1634435) - 'uneval' is behind a Realm flag (Bug 1565170), but no removal is planned in the short-term future. - Some minor GC API changes (Bugs 1569564 and 1633405) - Error reporting has had some tweaks, and error flags have been removed (Bug 1620583) - StructuredClone are now always thread-safe, simplifying an API change introduced in SM52 (Bug 1607791) Tested by: Stan, Freagarach, mammadori Closes #5861 Differential Revision: https://code.wildfiregames.com/D3168 This was SVN commit r24333.
