Subject: [PATCH/RFC 0/5] perf tool: event parsing enhancements

hi,
sending some enhancements for event parsing.

There are basically 2 features:
 - adding hardcoded term 'name' to allow specifying a name
   for the pmu event (patch 1/5)
 - implement hardcoded term 'branch_type' and allow specifying
   values like "branch_type=hv|any_ret|1" (patches 2-4/5)

Also, I was thinking of some overall event syntax documentation,
so I outlined something in patch 5/5. It's unfinished, highly
mistyped and partly stolen stuff.
What I'd expect would be some feedback about the form. Like what
it should look like.. event syntax + description of each event
type, modifiers etc.. please be gentle, it's RFC ;)


Attached patches:
 1/5 perf, tool: Add hardcoded name term for pmu events
 2/5 perf, tool: Split term type into value type and term type
 3/5 perf, tool: Add list type for event term parsing
 4/5 perf, tool: Add pmu event parse support for branch_sample_type values
 5/5 perf, tool: Add events specification doc

thanks,
jirka
