* fixed malloc corruption in target->debug_reason
* GDB remote server will now remain online even if the target
is in a funny state, e.g. if it requires a reset, it is
running while GDB is not in the continue or step packet,
e.g. via monitor resume/halt commands in GDB script.
* Added some _DEBUG_GDB_IO_ debug tools
* Fixed a couple of GDB server lockups, e.g. when O packets
detect a severed connection
* added ACK upon connection (send +).
* added keep-alive messages to reset so GDB protocol remains happy.
* fixed crash when timing out connection to GDB
