[cdt-debug-dev] CDI changes

["Alain Magloire" <alain@xxxxxxx>]

Heads up,

  Let's get the bad news out of the way 8-).
  In the head some heavy changes/refactoring coming, a brief overview:


A brief overview of some the changes

The CDI API:

- new Managers additions:
	- ICDISession.getVariableManager()
	- ICDISession.getExpressionManager()
	- ICDISession.getRegisterManager()
  rationale:
	The managers are responsible for things like registers, variables,
	signals, shareLibraries, breakpoints, expressions, etc ...
	Every time the target is suspended, they try to update. For example
	the SharedLibraryManger will call "info shared" to detect new
	shared object dlopen/dlclose or the RegisterManager will proble all
	the registers to see changes.  Some targets may not like
	this type of probing, so we can turn off this behaviour on a manager
	basis.

- new methods:
	- ICDIVariable.getStackFrame()
	- ICDIStackFrame.getThread()
	- ICDIThread.getTarget()
	- ICDITarget.getSession()
  rationale:
	will be possible to trace back i.e. this local variable came
	from this stackframe, from this thread, from this target etc ..

In the  MI --> CDI implementation some heavy factoring, that will
affect the external users of that plugin:

- Refactor/Rename: CSession --> Session
- Refactor/Rename: CTarget  --> Target
- Refactor/Rename: CThread  --> Thread
