cover 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:
git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
perf/fixes

thanks,
jirka

perf stat: Add 'identifier' flag to 'struct perf_stat_config'

Add 'identifier' flag to 'struct perf_stat_config' to carry the info whether to use PERF_SAMPLE_IDENTIFIER for events.

This makes create_perf_stat_counter() independent.

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.

Quoted 6 lines

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

Also available in here:
git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git

Thanks, applied,
