[cdt-dev] binary-less debugging

[Elena Laskavaia <ELaskavaia@xxxxxxx>]

I want to fix CDI launch (CDIDebugModel.newDebugTarget) to make binary 
argument optional (i.e. null possible),
because passing debugging binary for many cases does not make any sense 
- such as for JTag debugging.
In this case it launch gdb without binary argument, and set-up can use 
gdb commands to set symbol file, etc.

It does not mean that it would be optional in UI, default debug launch 
still requires it.

Any objections?
