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().

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.

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.

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.

Add a perf_evsel__open() function to libperf.
It's a simplified version of evsel__open() without the fallback
mechanism.
We can try to merge it in the future to libperf, but it has many
details, lets start simple, requiring the latest kernel, perf should
continue using its evsel__open() version, continuing to support running
on older kernels when possible.

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
