commit 44cfdef0a40d6c5d4514a927d9e46f5c2acc1586
Author: Marc Schink <de...@za...>
Date:   Fri Jun 14 16:19:56 2024 +0200

    server/gdb: Restructure commands
    
    Use a command group 'gdb' with subcommands instead of individual
    commands with 'gdb_' prefix.
    
    The old commands are still available to ensure backwards compatibility,
    but are marked as deprecated.
