perf llvm: Use strerror_r instead of the thread unsafe strerror one (2016-03-23 17:42:21 -0300)

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

User visible:

- Fix documentation of :ppp modifier in 'perf list' (Andi Kleen)

- Fix silly nodes bitfield bits/bytes length assertion in 'perf bench numa' (Jakub Jelen)

- Remove redundant CPU output in libtraceevent (Steven Rostedt)

- Remove 'core_id' check in topology 'perf test' (Sukadev Bhattiprolu)

Infrastructure:

- Record text offset in dso to calculate objdump address, to use with
modules in addition to vDSO symbol address calculations (Wang Nan)

- Move utilities.mak from perf to tools/scripts/ (Arnaldo Carvalho de Melo)

- Add cpumode to the perf_sample struct, this way we don't need to pass
the union event to the machine and thread resolving routines, shortening
function signatures and allowing the future introduction of a way
to use tracepoint events instead of the unavailable HW cycles counter on
powerpc guests in perf kvm by just hooking on perf_evsel__parse_sample,
at the end (Arnaldo Carvalho de Melo)

- Remove/unexport die() related infrastructure, that at some point will
finally be removed (Arnaldo Carvalho de Melo)

- Adopt linux/stringify.h from the kernel sources, not to touch this
kernel header from tools/ (Arnaldo Carvalho de Melo)

- Stop using strbuf for things we can instead trivially use libc's asprintf()
(Arnaldo Carvalho de Melo)

- Ditch tools/lib/util/abspath.c, its only exported function was used at just
one place and can be replaced by libc's realpath() (Arnaldo Carvalho de Melo)

- Use strerror_r() in the llvm infrastructure, tread safe, its what is used
elsewhere in tools/perf/ (Arnaldo Carvalho de Melo)

Cleanups:

- Removed misplaced or needless __maybe_unused/export (Arnaldo Carvalho de Melo)
