uhd: reworked time_spec_t to be more flexible: arithmetic, comparison operators...

Replaced nsecs with fractional seconds in units of seconds.
Replaced nsecs and secs members with public function members.
time_spec_t has a more diverse set of constructors and methods.
It can handle the cases where frac secs are greater than 1 second.
