* optimize ram block handling Save the last element of the ram_list. This allows to faster find where to add new elements when they are not bigger then page size. * save ram_list freed this keeps the optimization for find_ram_offset() intact after snapshot restore. * cow only clear the tlb of affected pages * update flatview when possible Building each flatview new when the memory has changed is quite expensive when many MemoryRegions are used. This is an issue when using snapshots. * update benchmark for new api * save flatview in context this avoids rebuilding the flatview when restore a context. * init context flatview with zero * address_space_dispatch_clear remove subpage with higher priority * docutemnt the options for UC_CTL_CONTEXT_MODE Specialy stress that with UC_CTL_CONTEXT_MEMORY it is not possible to use the context with a different unicorn object.
