Recent commit broke command name strip in perf_event__get_comm_ids
function. It replaced left to right search for '\n' with rtrim, which
actually does right to left search. It occasionally caught earlier '\n'
and kept trash in the command name.

Keeping the ltrim, but moving back the left to right '\n' search
instead of the rtrim.

'perf mem report' doesn't display the data source snoop indication correctly.

In the kernel API the definition is:

  #define PERF_MEM_SNOOP_NONE     0x02 /* no snoop */
  #define PERF_MEM_SNOOP_HIT      0x04 /* snoop hit */
  #define PERF_MEM_SNOOP_MISS     0x08 /* snoop miss */

but the table used by the perf tools exchanged "Hit" and "Miss":

        "None",
        "Miss",
        "Hit",

Fix the table in perf.

Merge tag 'perf-core-for-mingo-4.12-20170419' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core

Pull perf/core cleanups from Arnaldo Carvalho de Melo:

 - Introduce new header files out of the hodge-podge that util/util.h
   became, trying to disentangle the includes hell that all C projects
   end up growing. This should help in build times, as changes to
   seemingly unrelated files (util.h included tons of headers) won't
   trigger a rebuild of most object files.

 - Use equivalent facilities found in the kernel source code base
   originated tools/include/ header files, such as __stringify(),
   ARRAY_SIZE, that has extra checks (__must_be_array()), etc.

 - For that get some more files from the kernel sources, like
   include/linux/bug.h, some just with the bits needed at this time.

 - Use the headers where facilities declared in them are used, such
   as PRIxu(32,64) macros (inttypes.h), errno defines (errno.h), etc.

 - Remove various leftovers from the initial code base we copied from
   git.git: FLEX_ARRAY, etc.
