Provide helper for retrying partial vectored I/O. compute_remaining_iovec() is a re-usable routine for retrying after pg_readv() or pg_writev() reports a short transfer. This will gain new users in a later commit, but can already replace the open-coded equivalent code in the existing pg_pwritev_with_retry() function.
