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.

-libperf tutorial
-================
-
-Compile and install libperf from kernel sources
-===============================================
-.. code-block:: bash
-
-  git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
-  cd linux/tools/perf/lib
-  make
-  sudo make install prefix=/usr
-
-Libperf object
-==============
-The libperf library provides several high level objects:
-
-struct perf_cpu_map
-  Provides a cpu list abstraction.
-
-struct perf_thread_map
-  Provides a thread list abstraction.
-
-struct perf_evsel
-  Provides an abstraction for single a perf event.
-
-struct perf_evlist
-  Gathers several struct perf_evsel object and performs functions on all of them.
-
-The exported API binds these objects together,
-for full reference see the libperf.7 man page.
-
-Examples
-========
-Examples aim to explain libperf functionality on simple use cases.
-They are based in on a checked out linux kernel git tree:
-
-.. code-block:: bash
-
-  $ cd tools/perf/lib/Documentation/tutorial/
-  $ ls -d  ex-*
-  ex-1-compile  ex-2-evsel-stat  ex-3-evlist-stat
-
-ex-1-compile example
-====================
-This example shows the basic usage of *struct perf_cpu_map*,
-how to create it and display its cpus:
-
-.. code-block:: bash
-
-  $ cd ex-1-compile/
-  $ make
-  gcc -o test test.c -lperf
-  $ ./test
-  0 1 2 3 4 5 6 7
-
-
-The full code listing is here:
-
-.. code-block:: c
-
-   1 #include <perf/cpumap.h>
-   2
-   3 int main(int argc, char **Argv)
-   4 {
-   5         struct perf_cpu_map *cpus;
-   6         int cpu, tmp;
-   7
-   8         cpus = perf_cpu_map__new(NULL);
-   9
-  10         perf_cpu_map__for_each_cpu(cpu, tmp, cpus)
-  11                 fprintf(stdout, "%d ", cpu);
-  12
-  13         fprintf(stdout, "\n");
-  14
-  15         perf_cpu_map__put(cpus);
-  16         return 0;
-  17 }
-
-
-First you need to include the proper header to have *struct perf_cpumap*
-declaration and functions:
-
-.. code-block:: c
-
-   1 #include <perf/cpumap.h>
-
-
-The *struct perf_cpumap* object is created by *perf_cpu_map__new* call.
-The *NULL* argument asks it to populate the object with the current online CPUs list:
-
-.. code-block:: c
-
-   8         cpus = perf_cpu_map__new(NULL);
-
-This is paired with a *perf_cpu_map__put*, that drops its reference at the end, possibly deleting it.
-
-.. code-block:: c
-
-  15         perf_cpu_map__put(cpus);
-
-The iteration through the *struct perf_cpumap* CPUs is done using the *perf_cpu_map__for_each_cpu*
-macro which requires 3 arguments:
-
-- cpu  - the cpu numer
-- tmp  - iteration helper variable
-- cpus - the *struct perf_cpumap* object
-
-.. code-block:: c
-
-  10         perf_cpu_map__for_each_cpu(cpu, tmp, cpus)
-  11                 fprintf(stdout, "%d ", cpu);
