One needs to use perf_evsel__name() so that if needed the name gets
synthesized and stored in evsel->name, from where perf_evsel__name()
will serve from them on.

Adding automated test for parsing terms out of the event grammar.
Also slightly changing current event parsing test functions to
follow up more generic namespace.

Adding a new hardcoded term 'name' allowing to specify a name for the
pmu event. The term is defined along with standard pmu terms. If no
'name' term is given, the event name follows following template:

    "raw 0x<perf_event_attr::config>"

running:
    perf stat -e cpu/config=1,name=krava1/u ls

will produce following output:
    ...
    Performance counter stats for 'ls':
                 0 krava1
    ...

running:
    perf stat -e cpu/config=1/u ls

will produce following output:
    ...
    Performance counter stats for 'ls':
                 0 raw 0x1
    ...

Moving event parsing specific tests into separated file:

  util/parse-events-test.c

Also changing the code a bit to ease running separate tests.
