  tools lib traceevent: Use 'const' in variables pointing to const strings (2012-11-09 17:42:47 -0300)

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

. Add a 'link' method for hists, so that we can have the leader with
  buckets for all the entries in all the hists.  This new method
  is now used in the default 'diff' output, making the sum of the 'baseline'
  column be 100%, eliminating blind spots. Now we need to use this
  for 'diff' with > 2 perf.data files and for multi event 'report' and
  'annotate'.

. libtraceevent fixes for compiler warnings trying to make perf it build
  on some distros, like fedora 14, 32-bit, some of the warnings really
  pointed to real bugs.

. Remove temp dir on failure in 'perf test', fix from Jiri Olsa.

. Fixes for handling data, stack mmaps, from Namhyung Kim.

. Fix live annotation bug related to recent objdump lookup patches, from
  Namhyung Kim

. Don't try to follow jump target on PLT symbols in the annotation browser,
  fix from Namhyung Kim.

. Fix leak on hist_entry delete, from Namhyung Kim.

. Fix a CPU_ALLOC related build error on builtin-test, from Zheng Liu.
