pack v4 format does not go along well with pack size limit feature. v4
requires to know the number of objects in the pack in advance in order
to contruct various tables after pack header. When pack size is
limited, we don't know this number until we write objects out and hit
it. By then the only option we have is rewrite the pack and update the
tables.
