perf tools: Add hardcoded name term for pmu events

Browse Source 
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
    ...
