e9c4bcdd34 perf symbols: add Java demangling support 
Add Java function descriptor demangling support.  Something bfd cannot
do.

Use the JAVA_DEMANGLE_NORET flag to avoid decoding the return type of
functions.

Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

New features:

 - Add 'L' hotkey to dynamicly set the percent threshold for histogram
   entries and callchains, i.e. dynamicly do what the --percent-limit
   command line option to 'top' and 'report' does. (Namhyung Kim)

Infrastructure changes:

 - Per hists field and sort lists, that will be used, for instance,
   in the c2c tool (Jiri Olsa)

Documentation changes:

 - Update documentation of --sort and --perf-limit options
   for 'perf report' (Namhyung Kim)

Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

 - tracepoint_error() can receive e=NULL, robustify it, fixes a problem noticed
   with a very specific combination: Machine with Intel PT (e.g. Broadwell),
   kernel with no perf_event_attr.context_switch feature (e.g. 4.2) and unreadable
   tracefs (for instance !root users), making the fallback from
   perf_event_attr.context_switch to the sched:sched_switch tracepoint to fail
   reading its info from tracefs, fix it. (Adrian Hunter)

 - Fix segfault in intel PT, by making it follow the 'struct thread' lifetime cycle
   checking expectations, noticed for instance, when processing perf.data files with
   Intel PT data using 'perf script' and when exiting 'perf report' (Adrian Hunter)

 - Fix CFI usage from .eh_frame and .debug_frame, which sometimes requires that we
   fallback from .eh_frame to .debug_frame in architectures such as PowerPC (Hemant Kumar)

51fd2df1e8 perf stat: Fix interval output values 
We broke interval data displays with commit:

  3f416f22d1 ("perf stat: Do not clean event's private stats")

This commit removed stats cleaning, which is important for '-r' option
to carry counters data over the whole run. But it's necessary to clean
it for interval mode, otherwise the displayed value is avg of all
previous values.

Before:
  $ perf stat -e cycles -a -I 1000 record
  #           time             counts unit events
       1.000240796         75,216,287      cycles
       2.000512791        107,823,524      cycles

  $ perf stat report
  #           time             counts unit events
       1.000240796         75,216,287      cycles
       2.000512791         91,519,906      cycles

Now:
  $ perf stat report
  #           time             counts unit events
       1.000240796         75,216,287      cycles
       2.000512791        107,823,524      cycles

Notice the second value being bigger (91,.. < 107,..).

This could be easily verified by using perf script which displays raw
stat data:

  $ perf script
  CPU  THREAD       VAL         ENA         RUN        TIME EVENT
    0      -1  23855779  1000209530  1000209530  1000240796 cycles
    1      -1  33340397  1000224964  1000224964  1000240796 cycles
    2      -1  15835415  1000226695  1000226695  1000240796 cycles
    3      -1   2184696  1000228245  1000228245  1000240796 cycles
    0      -1  97014312  2000514533  2000514533  2000512791 cycles
    1      -1  46121497  2000543795  2000543795  2000512791 cycles
    2      -1  32269530  2000543566  2000543566  2000512791 cycles
    3      -1   7634472  2000544108  2000544108  2000512791 cycles

The sum of the first 4 values is the first interval aggregated value:

  23855779 + 33340397 + 15835415 + 2184696 = 75,216,287

The sum of the second 4 values minus first value is the second interval
aggregated value:

  97014312 + 46121497 + 32269530 + 7634472 - 75216287 = 107,823,524

   tests, more can be done to filter out uninteresting info in the output
   (Arnaldo Carvalho de Melo)

 - Improve the 'perf test bp_signal' test (Wang Nan)

 - Check environment before starting the BPF 'perf test', so that we can just
