[GIT PULL||RFC 00/11] perf library and regression testing improvements

[Arnaldo Carvalho de Melo]

Hi Ingo, Peter et al,

	Trying to simplify using the API for tools and more specifically for
'perf test' regression tests, please take a look, perhaps starting from the last
changeset, that implements a regression test using the resulting library API.

	It also reduces the 'perf' tool footprint by not using hard coded array
sizes, more need to be done, but should be a good start, one changeset shows a
good reduction in BSS use.

	Suggestions for naming most welcome, I thought about using "event__",
but that is taken, "perf_event__", but thought it would clash with "event_t",
so used the jargon used for the '-e' parameters: "Event Selector", but don't
like it that much, what do you think?

	Writing the first regression test I think there are more ways to simplify,
on top of these, like not requiring a thread_map, i.e. passing NULL for that
parameter would mean: self-monitor, etc.

        If you are pleased as-is, please pull from:

Arnaldo Carvalho de Melo (11):
  perf tools: Introduce event selectors
  perf evsel: Adopt MATCH_EVENT macro from 'stat'
  perf util: Move do_read from session to util
  perf evsel: Delete the event selectors at exit
  perf evsel: Steal the counter reading routines from stat
  perf evsel: Introduce per cpu and per thread open helpers
  perf tools: Refactor cpumap to hold nr and the map
  perf tools: Refactor all_tids to hold nr and the map
  perf evsel: Use {cpu,thread}_map to shorten list of parameters
  perf evsel: Auto allocate resources needed for some methods
  perf test: Add test for counting open syscalls
