perf thrad_map: Add comm string into array
Adding support to hold comm name together with pids in 'struct
thread_map'. It will be useful for --per-thread option to display task
pid together with task name.
Adding thread_map__read_comms function that reads/set
comm string for the 'struct thread_map'.
Getting the task name from /proc/$pid/comm.
