Tzvetomir Stoyanov (VMware) 56dce86819 libperf: Add API for allocating new thread map array 
The existing API perf_thread_map__new_dummy() allocates new thread map
for one thread. I couldn't find a way to reallocate the map with more
threads, or to allocate a new map for more than one thread.

Having multiple threads in a thread map is essential for some use cases.
That's why a new API is proposed, which allocates a new thread map for
given number of threads: perf_thread_map__new_array()

Jiri Olsa 3d970601da libperf: Change tests to single static and shared binaries 
Make tests to be two binaries 'tests_static' and 'tests_shared', so the
maintenance is easier.

Adding tests under libperf build system, so we define all the flags just
once.

Adding make-tests tule to just compile tests without running them.

Ian Rogers bba2ea17ef libperf tests: If a test fails return non-zero 
If a test fails return -1 rather than 0. This is consistent with the
return value in test-cpumap.c

Jiri Olsa 3ce311afb5 libperf: Move to tools/lib/perf 
Move libperf from its current location under tools/perf to a separate
directory under tools/lib/.

Also change various paths (mainly includes) to reflect the libperf move
to a separate directory and add a new directory under MANIFEST.
