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.
