Fix arena chunk purge/dealloc race conditions. Fix arena_chunk_dealloc() to put the new spare in a consistent state before dropping the arena mutex to deallocate the previous spare. Fix arena_run_dalloc() to insert a newly dirtied chunk into the chunks_dirty list before potentially deallocating the chunk, so that dirty page accounting is self-consistent.
