    gdb/cli: add a 'normal_stop' option to 'cli_suppress_notification'
    
    Extend the 'cli_suppress_notification' struct with a new field,
    'normal_stop', that can be used for checking if printing normal stop
    events on the CLI should be suppressed.
    
    This patch only introduces the flag.  The subsequent patch adds a user
    command to turn the flag off/on.
