Wang Nan 65aea23387 perf evlist: Add API to pause/resume 
perf_evlist__toggle_{pause,resume}() are introduced to pause/resume
events in an evlist. Utilize PERF_EVENT_IOC_PAUSE_OUTPUT ioctl.

Following commits use them to ensure overwrite ring buffer is paused
before reading.

[ Return -1, like all other ioctl() usage in evlist.c, rename 'pause'
