libperf: Add perf_thread_map struct
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.
