    Extend gdbstub to support more features of gdb remote protocol to keep
    gdb-7 and emacs gud mode happy:
    
     (*) The D command.  Detach debugger.
    
     (*) The H command.  Handle setting the target thread by ignoring it.
    
     (*) The qAttached command.  Indicate we 'attached' to an existing process.
    
     (*) The qC command.  Indicate that the current thread ID is 0.
    
     (*) The qOffsets command.  Indicate that no relocation has been done.
    
     (*) The qSymbol:: command.  Indicate that we're not interested in looking up
         any symbol addresses.
    
     (*) The qSupported command.  Indicate the maximum packet size and the fact
         that reverse step and continue aren't supported.
    
     (*) The vCont? command.  Indicate that we don't support any of its variants.
    
    Also make it possible to trace the commands and replies without tracing
    the individual character I/O.
