rt-graph: input to real-time plots is processed using real-time timestamps

Each plot processes only the records which fit within the time window displayed.
When passing records into a real-time plot, kernelshark will now decide if a
record is within the current time window using real-time timestamps, instead of
the old ftrace timestamps.

This change also enables infinite zooming into the real-time plots.
