perf tools: change machine__findnew_thread() to set thread pid
Add a new parameter for 'pid' to machine__findnew_thread().
Change callers to pass 'pid' when it is known.
Note that callers sometimes want to find the main thread
which has the memory maps. The main thread has tid == pid
so the usage in that case is:
machine__findnew_thread(machine, pid, pid)
whereas the usage to find the specific thread is:
machine__findnew_thread(machine, pid, tid)
