perf test: Fix dwarf unwind using libunwind.

Perf tool fails to unwind user stack if the event raises in a shared
object. This patch improves tests/dwarf-unwind.c to demonstrate the
problem by utilizing commonly used glibc function "bsearch". If perf is
not statically linked, the testcase will try to unwind a mixed call
trace.

By debugging libunwind I found that there is a bug in unwind-libunwind:
it always passes 0 as segbase to libunwind, cause libunwind unable to
locate debug_frame entry fir first level ip address (I add some more
debugging output into libunwind to make things clear):

>_Uarm_dwarf_find_debug_frame: start_ip = 10be98, end_ip = 10c2a4
>_Uarm_dwarf_find_debug_frame: found debug_frame table `/lib/libc-2.18.so': segbase=0x0, len=7, gp=0x0, table_data=0x449388
>_Uarm_dwarf_search_unwind_table: call lookup:ip = b6cd3bcc, segbase = 0, rel_ip = b6cd3bcc
>lookup: e->start_ip_offset = bcf18 (rel_ip = b6cd3bcc)
>lookup: e->start_ip_offset = 6d314 (rel_ip = b6cd3bcc)
>lookup: e->start_ip_offset = 33d0c (rel_ip = b6cd3bcc)
...
>lookup: e->start_ip_offset = 15d0c (rel_ip = b6cd3bcc)
>lookup: e->start_ip_offset = 15c40 (rel_ip = b6cd3bcc)
>_Uarm_dwarf_search_unwind_table: IP b6cd3bcc inside range b6c12000-b6d4c000, but no explicit unwind info found
>put_rs_cache: unmasking signals/interrupts and releasing lock
>_Uarm_dwarf_step: returning -10
>_Uarm_step: dwarf_step()=-10

This patch passes map->start as segbase to dwarf_find_debug_frame(), so
di will be initialized correctly.

In addition, dso and executable are different when setting segbase. This
patch first check whether the elf is executable, and pass segbase only
for shared object.

Pull perf events update from Ingo Molnar:
"On the kernel side there's few changes, the one that stands out is
PEBS machine state sampling support on x86, by Stephane Eranian.

On the tooling side:

User visible tooling changes:

- 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)

- 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)

- Fallback to kallsyms when using the minimal 'ELF' loader (Arnaldo
Carvalho de Melo)

- Fix annotation with kcore (Adrian Hunter)

- Support source line numbers in annotate using a hotkey (Andi Kleen)

- Callchain improvements including:
* Enable printing the srcline in the history
* Make get_srcline fall back to sym+offset (Andi Kleen)

- TUI hist_entry browser fixes, including showing missing overhead
value for first level callchain. Detected comparing the output of
--stdio/--gui (that matched) with --tui, that had this problem.
(Namhyung Kim)

- Support handling complete branch stacks as histograms (Andi Kleen)

Tooling infrastructure changes:

- Prep work for supporting per-pkg and snapshot counters in 'perf
stat' (Jiri Olsa)

- 'perf stat' refactorings, moving stuff from it to evsel.c to use in
per-pkg/snapshot format changes (Jiri Olsa)

- Add per-pkg format file parsing (Matt Fleming)

- Clean up libelf feature support code (Namhyung Kim)

- Add gzip decompression support for kernel modules (Namhyung Kim)

- More prep patches for Intel PT, including a a thread stack and more
stuff made available via the database export mechanism (Adrian
Hunter)

- 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)

- 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)

... and lots of other fixes and smaller improvements"
