80ab2987a0 libperf: Add perf_evlist__poll() function 
Move perf_evlist__poll() from tools/perf to libperf, it will be used in
the following patches.

And rename the existing perf's function to evlist__poll().

428dab813a libperf: Merge libperf_set_print() into libperf_init() 
The libperf_set_print() function needs to be called in any case so let's
merge it with libperf_init(), so we have just one init function.

20f2be1d48 libperf: Move 'page_size' global variable to libperf 
We need the 'page_size' variable in libperf, so move it there.

Add a libperf_init() as a global libperf init function to obtain this
value via sysconf() at tool start.

Committer notes:

Add internal/lib.h to tools/perf/ files using 'page_size', sometimes
replacing util.h with it if that was the only reason for having util.h
included.

80dc2b3e25 libperf: Adopt simplified perf_evlist__open()/close() functions from tools/perf 
Add the following functions:

  perf_evlist__open()
  perf_evlist__close()

It's a simplified version of perf's evlist__open() without the sampling
id index calculations. We can try to merge it in the future when we need
it in some new libperf user.

Also adopt some helper evlist traversing macros. In the future we can
remove them from util/evlist.h, but that requires also some other
changes.

It's a simplified version of evsel__open() without the fallback

We can try to merge it in the future to libperf, but it has many

continue using its evsel__open() version, continuing to support running
on older kernels when possible.

So move the initialization of the core evlist (calling
perf_evlist__init()) to before perf_evlist__set_maps() in
evlist__init().

47f9bccc79 libperf: Add build version support 
Add a shared library version, generating the following files:

  $ ll tools/perf/lib/libperf.so*
  libperf.so -> libperf.so.0.0.1
  libperf.so.0 -> libperf.so.0.0.1
  libperf.so.0.0.1

Committer testing:

One has to build just libbperf to get this, building perf so far doesn't
trigger this, i.e. I tried:

  $ make O=/tmp/build/perf -C tools/perf

And the files above were not created, so one has to do:

  $ make O=/tmp/build/perf -C tools/perf/lib/
  make: Entering directory '/home/acme/git/perf/tools/perf/lib'
    LINK     /tmp/build/perf/libperf.so.0.0.1
  make: Leaving directory '/home/acme/git/perf/tools/perf/lib'
  $ ls -la /tmp/build/perf/*.so.*
  lrwxrwxrwx. 1 acme acme    16 Jul 22 15:37 /tmp/build/perf/libperf.so.0 -> libperf.so.0.0.1
  -rwxrwxr-x. 1 acme acme 16368 Jul 22 15:37 /tmp/build/perf/libperf.so.0.0.1
