* fixed malloc corruption in target->debug_reason

Browse Source 
* 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
