perf probe: Add --quiet option to suppress output result message (2014-10-27 17:16:34 -0200)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible:

* 'perf probe' --demangle typo fix and a new --quiet option (Masami Hiramatsu)

* Fix report -F (abort, in_tx, mispredict, etc) segfaults for sample.data files
without branch info (Jiri Olsa)

* Don't open the DWARF info multiple times, keeping instead a dwfl handle
in struct dso, greatly speeding up 'perf report' on powerpc. (Sukadev Bhattiprolu)

* Add patch that should have went in a previous patchkit to use global cache
provided by libunwind (Namhyung Kim)

* Make CPUINFO_PROC an array to support different kernels, problem
detected when the information reported via /proc/cpuinfo changed on ARM (Wang Nan)

* Introduce PARSE_OPT_DISABLED option flag and use it to avoid showing
undersired options in tools that provides frontends to 'perf record', like
sched, kvm, etc (Namhyung Kim)

Infrastructure:

* More Intel PT work, including a facility to export sample data (comms,
threads, symbol names, etc) in a database friendly way, with an script to use
this to create a postgresql database. (Adrian Hunter)

* Use make sure that thread->mg->machine points to the machine where
the thread exists (it was being set only for the kmaps kernel modules
case, do it as well for the mmaps) and use it to shorten function
signatures (Arnaldo Carvalho de Melo)
