This function MUST handle the 'c' and 's' command packets,
as well packets to set / remove a hardware breakpoint, if used.
If there are additional packets which the hardware needs to handle,
they are handled here. The code should return -1 if it wants to
process more packets, and a <code class="constant">0</code> or <code class="constant">1</code> if it wants to exit from the
kgdb callback.
