[RFCv3 0/9] perf tool: parser generator for events parsing

[Jiri Olsa <jolsa@redhat.com>]

hi,
I'd never imagine how much code I need to introduce before
I could push through the event grouping patch.. ;)

Here's new version of event parsing patchset. To summarize:
 - adding event parser bison/flex generator
 - the event syntax stays as it was
 - adding event format file sysfs attribute
   for pmu device
 - adding new syntax to specify raw events based
   on the sysfs pmu's format attribute
   eg. "cpu/config=1,config1=2,config2=3/u"

There are helping patches 1-4, which I did not want to
mangle with the actual change. Patches 5-9 implement
the feature itself.

I consider this patchset as RFC. Everything seems to work,
but I did not want to spend much time over it before any
fundamental design comments.. ;)

Attached patches:
 1/9 perf, tool: Make perf_evlist__splice_list_tail global
 2/9 perf, tool: Remove unused functions from debugfs object
 3/9 perf, tool: Add sysfs mountpoint interface
 4/9 perf, tool: Add bitmap_or function into bitmap object
 5/9 perf: Add sysfs format attribute for pmu device
 6/9 perf, tool: Add parser generator for events parsing
 7/9 perf, tool: Add config options support for event parsing
 8/9 perf, tool: Add perf pmu object to access pmu format
 9/9 perf, tool: Add support to specify pmu style event

thanks for comments,
jirka
