This adds new methods AllocateSharedPages, ReserveForSharedMemoryMapping and CanAllocateSharedPages to v8::PageAllocator, which if overridden allows the platform to declare that it supports allocation and remapping of shared memory. This interface is currently a work in progress so the new methods are marked "INTERNAL ONLY" and they may change without being first deprecated. An implementation of PageAllocator is provided that can allocate and map shared memory on Linux and Android, but no other platforms are yet supported. While Windows is not supported the interface has been designed to make this possible as AllocateSharedPages returns a SharedMemory object that wraps the shared memory and provides its own remap function. This should allow the SharedMemory object on windows to contain a mapping a to hFileMappingObject as required by MapViewOfFileEx.
