perf stat: Fallback to user only counters when perf_event_paranoid > 1 (2016-05-12 16:25:18 -0300)

----------------------------------------------------------------
perf/urgent fixes:

User visible:

- Fallback to usermode only counters when perf_event_paranoid > 1, which
is the case now (Arnaldo Carvalho de Melo)

- Do not reassign parg after collapse_tree() in libtraceevent, which
may cause tool crashes (Steven Rostedt)

Build fixes:

- Fix the build on Fedora Rawhide, where readdir_r() is deprecated and
also wrt -Werror=unused-const-variable= + x86_32_regoffset_table on
!x86_64 (Arnaldo Carvalho de Melo)

- Fix the build on Ubuntu 12.04.5, where dwarf_getlocations() isn't
available, i.e. libdw-dev < 0.157 (Arnaldo Carvalho de Melo)
