as it accentally contained the wrong set of patches. These will be
submitted separately.

- * tfrc_scaled_sqrt  -  Compute scaled integer sqrt(x) for 0 < x < 2^22-1
- * Uses scaling to improve accuracy of the integer approximation of sqrt(). The
- * scaling factor of 2^10 limits the maximum @sample to 4e6; this is okay for
- * clamped RTT samples (dccp_sample_rtt).
- * Should best be used for expressions of type sqrt(x)/sqrt(y), since then the
- * scaling factor is neutralised. For this purpose, it avoids returning zero.
