Subject: [PATCH] Debugger: Implement Create/Attach on
 LocalTargetHostInterface.

LocalTargetHostInterface:
- Implement the create and attach functionality. In theory, this completes
  everything that's needed in order to adjust the main application to do
  all debugger interface creation via the roster.
