perf test: Suppress libtraceevent warnings
Currently libtraceevent emits warning on unsupported event formats.
However it'd be better to see them only -v option is given. To do that,
it needs to override the warning() function which is used in the
libtracevent. Thus add set_warning_routine() same as set_die_routine()
and check the verbose flag in our warning routine.
Before:
# perf test 5
5: parse events tests :
Warning: [kvmmmu:kvm_mmu_get_page] bad op token {
Warning: [kvmmmu:kvm_mmu_sync_page] bad op token {
Warning: [kvmmmu:kvm_mmu_unsync_page] bad op token {
Warning: [kvmmmu:kvm_mmu_prepare_zap_page] bad op token {
Warning: [kvmmmu:fast_page_fault] function is_writable_pte not defined
...
Ok
After:
# perf test 5
5: parse events tests : Ok
