[PATCH 12/55] perf tools: Enable config raw and numeric events

[Wang Nan]

This patch allows setting config terms for raw and numeric events.
For example:

 # perf stat -e cycles/name=cyc/ ls
 ...
 1821108      cyc
 ...

 # perf stat -e r6530160/name=event/ ls
 ...
 1103195      event
 ...

 # perf record -e cycles -e 4:0x6530160/name=evtx,call-graph=fp/ -a sleep 1
 ...
 # perf report --stdio
 ...
 # Samples: 124  of event 'cycles'
 46.61%     0.00%  swapper        [kernel.vmlinux]            [k] cpu_startup_entry
 41.26%     0.00%  swapper        [kernel.vmlinux]            [k] start_secondary
 ...
 # Samples: 91  of event 'evtx'
 ...
 93.76%     0.00%  swapper      [kernel.vmlinux]            [k] cpu_startup_entry
         |
         ---cpu_startup_entry
            |
            |--66.63%--call_cpuidle
            |          cpuidle_enter
            |          |
 ...

3 test cases are introduced to test config terms for symbol, raw and
numeric events.
