libperf cpumap: Replace usage of perf_cpu_map__new(NULL) with perf_cpu_map__new_online_cpus()

Passing NULL to perf_cpu_map__new() performs
perf_cpu_map__new_online_cpus(), just directly call
perf_cpu_map__new_online_cpus() to be more intention revealing.

libperf: Add man pages

Change the man page generation to asciidoc, because it's easier to use
and has been more commonly used in related projects. Remove the current
rst pages.

Add 3 man pages to have a base for more additions:

libperf.3 - overall description
libperf-counting.7 - counting basics explained on simple example
libperf-sampling.7 - sampling basics explained on simple example

The plan is to add more man pages to cover the basic API.

The build generates html and man pages:

$ cd tools/lib/perf/Documentation
$ make
ASCIIDOC libperf.xml
XMLTO libperf.3
ASCIIDOC libperf-counting.xml
XMLTO libperf-counting.7
ASCIIDOC libperf-sampling.xml
XMLTO libperf-sampling.7
ASCIIDOC libperf.html
ASCIIDOC libperf-counting.html
ASCIIDOC libperf-sampling.html

Add the following install targets:

install-man - man pages
install-html - html version of man pages
install-examples - examples mentioned in the man pages
