Add perf_thread_map struct to libperf. It's added as a declaration into into: include/perf/threadmap.h which will be included by users. The perf_thread_map struct definition is added into: include/internal/threadmap.h which is not to be included by users, but shared within perf and libperf. We tried the total separation of the perf_thread_map struct in libperf, but it lead to complications and much bigger changes in perf code, so we decided to share the declaration.
