Reduce gpsd log verbosity a lot.

Way too much logging was happening at LOG_IO level, which is intended for
watching data traffic in and out of the daemon rather than all the minutiae
of data analysis - that's LOG_DATA.

Also, LOG_DATA gets pushed down two levels.  The effect is that -D 5
means exactly what it did, but for purposes other than driver debugging
-D 4 now suffices.
