perf stat: Make some of the stat code generic

hi,
while going for the ability to store/display stat data in perf record/top I ended up with bunch of generic patches that make some of the stat functions standalone and simplify/reduce the builtin-stat.c code.

This patchset mostly separates the display functions into separate object, plus several other functions.

Also available in here:

perf/fixes

thanks,
jirka
