7fdc304e12 FEATURE: Add read_vcd -begin_time/-end_time activity windowing (#466)
* Add read_vcd -begin_time/-end_time activity windowing.

Limit VCD transition and duty counting to an optional time window so
activity annotation can ignore regions outside the interval of interest.

* Format VcdCount::setFilter parameters one per line.

* Address VCD begin/end review: VcdTime, sentinel, rename.

Use VcdTime and vcd_null_time instead of int64_t/-1, rename
VcdCount filter bounds to begin/end_time, rename the regression to
vcd_begin_end_time, and document read_vcd -begin_time/-end_time in
ChangeLog.txt.
