    tools: a few improvements in performance-log-viewer.py
    
    Fix searching for samples by thread name, in particular, when there
    are unnamed threads.
    
    Use GtkMenuButton, instead of GtkButton, for the find-samples
    header button.
    
    Add mnemonics to the find-samples popover.
