perf_counter tools: kerneltop: add real-time data acquisition thread
Decouple kerneltop display from event acquisition by introducing
a separate data acquisition thread. This fixes annnoying kerneltop
display refresh jitter and missed events.
Also add a -r <prio> option, to switch the data acquisition thread
to real-time priority.
