It is a bit curious place to draw the line; we want to make sure
that blob_entry can hold huge data, but in this step we do not mind
read_object_file() is not capable of going full 64-bit?
I guess I'll see soon enough why by reading later steps. I can see
that for the purpose of making write_entry() aware of the size_t,
this is necessary at the minimum.
Looking good.
