The D700 does not internally round the input frequency to the nearest

available frequency. Instead it returns an error code. This is an
issue for use with gpredict.  It is also inconsistent with other
backends, particularly the FT-857. (The rounding may occur in the radio
of the 857 but to the developer it appears transparent.)

This patch defines a simple wrapper around the th_set_freq call that
rounds the frequency to the nearest 5kHz.

Patch from Charles Suprin, AA1VS.
