Dave Taht abf70ef494 tc: support conversions to or from 64 bit nanosecond-based time 
Using a 32 bit field to represent time in nanoseconds results in a
maximum value of about 4.3 seconds, which is well below many observed
delays in WiFi and LTE, and barely in the ballpark for a trip past the
Earth's moon, Luna.

Using 64 bit time fields in nanoseconds allows us to simulate
network diameters of several hundred light-years. However, only
conversions to and from ns, us, ms, and seconds are provided.

The iproute2 64 bit api uses signed values for time. Being able to
represent positive or negative time allows us to calculate +/- deltas
between, for example, the CLOCK_TAI and CLOCK_REALTIME clocks.

Time related utility functions in tc_util.c are moved to lib/utils.c.
