Arnaldo Carvalho de Melo 96395cbbc7 tools lib string: Adopt prefixcmp() from perf and subcmd 
Both had copies originating from git.git, move those to
tools/lib/string.c, getting both tools/lib/subcmd/ and tools/perf/ to
use it.

Jiri Olsa 9d43f5e8df perf tools: Fix the code to strip command name 
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.

The util/event.h header needs PERF_ALIGN(), but wasn't including
linux/kernel.h, where it is defined, instead it was getting it by
luck by including map.h, which it doesn't need at all.

Andi Kleen 166ebdd244 perf mem: Fix display of data source snoop indication 
'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.
