perf record: Introduce thread local variable

Introduce thread local variable and use it for threaded trace streaming.
Use thread affinity mask instead of record affinity mask in affinity
modes. Use evlist__ctlfd_update() to propagate control commands from
thread object to global evlist object to enable evlist__ctlfd_*
functionality. Move waking and sample statistic to struct record_thread
and introduce record__waking function to calculate the total number of
wakes.
