perf buildid-cache: Support --list option
'perf buildid-cache' allows to add/remove files into cache but there is no option to list all cached files. Add --list option to list all _valid_ cached files. Ex, # perf buildid-cache --add /tmp/a.out # perf buildid-cache -l 8a86ef73e44067bca52cc3f6cd3e5446c783391c /tmp/a.out Signed-off-by: Ravi Bangoria <ravi.bangoria@linux.vnet.ibm.com> Acked-by: Jiri Olsa <jolsa@kernel.org> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Kate Stewart <kstewart@linuxfoundation.org> Cc: Krister Johansen <kjlx@templeofstupid.com> Cc: Masami Hiramatsu <mhiramat@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Philippe Ombredanne <pombredanne@nexb.com> Cc: Sihyeon Jang <uneedsihyeon@gmail.com> Cc: Thomas Gleixner <tglx@linutronix.de> Link: http://lkml.kernel.org/r/20180417041346.5617-3-ravi.bangoria@linux.vnet.ibm.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
