  1. Fix nasa#429, update OS_time_t definition to 64-bit ticks 

    Use a single 64-bit tick counter as OS_time_t, rather than
a split 32 bit seconds + 32 bit microseconds counter.

This benefits in several ways:

- increases the timing precision by 10x (0.1us ticks)
- increases the representable range by 400x (+/-14000 yrs)
- simplifies addition/subtraction (no carry over)
- avoids "year 2038" bug w/32-bit timestamps
