    Deprecate dbx mode
    
    GDB has a dbx emulation mode that adds a few aliases and helper
    commands.  This mode is barely documented and is very superficial
    besides.  I suspect it is rarely used, and I would like to propose
    deprecating it for GDB 12, and then removing it in GDB 13.
