    tools: a few improvements in performance-log-viewer.py
    
    In sample-search predicates, remove the "exclusive" parameter of
    the "function()" function, and replace it with optional "id" and
    "state" parameters, which limit the match to the call-stacks of
    matching threads, as per the "thread()" function.
    
    Sort the backtrace thread-list by thread ID.
