  r.curvenumber: replace python implementation with c version (#1550)

The previous Python version was used on a nominal sized region (nrows = 47104, ncols = 36785) and /usr/bin/time reported that wall-clock time was 1h33m52s, whereas this C implementation took 1m37.69s (a speedup of ~57.6x).
The module interface and outputs are unchanged; only the implementation has been ported to C.
