Jaroslav Škarvada 66dfdff03d perf tools: Add Python 3 support 
Added Python 3 support while keeping Python 2.7 compatibility.

Committer notes:

This doesn't make it to auto detect python 3, one has to explicitely ask
it to build with python 3 devel files, here are the instructions
provided by Jaroslav:

 ---
  $ cp -a tools/perf tools/python3-perf
  $ make V=1 prefix=/usr -C tools/perf PYTHON=/usr/bin/python2 all
  $ make V=1 prefix=/usr -C tools/python3-perf PYTHON=/usr/bin/python3 all
  $ make V=1 prefix=/usr -C tools/python3-perf PYTHON=/usr/bin/python3 DESTDIR=%{buildroot} install-python_ext
  $ make V=1 prefix=/usr -C tools/perf PYTHON=/usr/bin/python2 DESTDIR=%{buildroot} install-python_ext
 ---

We need to make this automatic, just like the existing tests for checking if
the python2 devel files are in place, allowing the build with python3 if
available, fallbacking to python2 and then just disabling it if none are
available.

So, using the PYTHON variable to build it using O= we get:

Before this patch:

  $ rpm -q python3 python3-devel
  python3-3.6.4-7.fc27.x86_64
  python3-devel-3.6.4-7.fc27.x86_64
  $ rm -rf /tmp/build/perf/ ; mkdir -p /tmp/build/perf ; make O=/tmp/build/perf PYTHON=/usr/bin/python3 -C tools/perf install-bin
  make: Entering directory '/home/acme/git/linux/tools/perf'
  <SNIP>
  Makefile.config:670: Python 3 is not yet supported; please set
  Makefile.config:671: PYTHON and/or PYTHON_CONFIG appropriately.
  Makefile.config:672: If you also have Python 2 installed, then
  Makefile.config:673: try something like:
  Makefile.config:674:
  Makefile.config:675:   make PYTHON=python2
  Makefile.config:676:
  Makefile.config:677: Otherwise, disable Python support entirely:
  Makefile.config:678:
  Makefile.config:679:   make NO_LIBPYTHON=1
  Makefile.config:680:
  Makefile.config:681: *** .  Stop.
  make[1]: *** [Makefile.perf:212: sub-make] Error 2
  make: *** [Makefile:110: install-bin] Error 2
  make: Leaving directory '/home/acme/git/linux/tools/perf'
  $

After:

  $ make O=/tmp/build/perf PYTHON=python3 -C tools/perf install-bin
  $ ldd ~/bin/perf | grep python
	libpython3.6m.so.1.0 => /lib64/libpython3.6m.so.1.0 (0x00007f58a31e8000)
  $ rpm -qf /lib64/libpython3.6m.so.1.0
  python3-libs-3.6.4-7.fc27.x86_64
  $

Now verify that when using the binding the right ELF file is loaded,
using perf trace:

  $ perf trace -e open* perf test python
     0.051 ( 0.016 ms): perf/3927 openat(dfd: CWD, filename: /etc/ld.so.cache, flags: CLOEXEC           ) = 3
<SNIP>
  18: 'import perf' in python                               :
     8.849 ( 0.013 ms): sh/3929 openat(dfd: CWD, filename: /etc/ld.so.cache, flags: CLOEXEC           ) = 3
<SNIP>
    25.572 ( 0.008 ms): python3/3931 openat(dfd: CWD, filename: /tmp/build/perf/python/perf.cpython-36m-x86_64-linux-gnu.so, flags: CLOEXEC) = 3
<SNIP>
 Ok
<SNIP>
  $

And using tools/perf/python/twatch.py, to show PERF_RECORD_ metaevents:

  $ python3 tools/perf/python/twatch.py

  #

And with this patch, but building normally, without specifying the
PYTHON=python3 part, which will make it use python2 if its devel files are
available, like in this test:

  $ make O=/tmp/build/perf -C tools/perf install-bin
  $ ldd ~/bin/perf | grep python
	libpython2.7.so.1.0 => /lib64/libpython2.7.so.1.0 (0x00007f6a44410000)
  $ ldd /tmp/build/perf/python_ext_build/lib/perf.so  | grep python
	libpython2.7.so.1.0 => /lib64/libpython2.7.so.1.0 (0x00007fed28a2c000)
