From: Derrick Stolee <dstolee@xxxxxxxxxxxxx>
In an effort to align write_midx_internal() with the chunk-format API,
continue to group necessary data into "struct write_midx_context". This
change collects the "uint32_t *pack_perm" and large_offsets_needed bit
into the context.
Update write_midx_object_offsets() to match chunk_write_fn.
