Hi Akio and everyone!

recently I started to work on debugger.  Attached is the current work.
I was able to stop a domain and disp under gdb the current ip.
Backtrace is not working.  I suppose it requires the ar.bsp value which has to 
be computed.
Also I didn't try on core images.

I am not yet planning to continue this work now.  If anyone wants to continue 
please tell.

Tristan.
