Allow for standard repl behavior within debugger context

[vspinu]

Would be nice to have full featured repl experience within the debugger. Being able to freely eval arbitrary forms and instrument other forms within the debugger is very useful. Also see this comment.

There are two ways to go about it. Either mimic interruptible-eval within the debugger (might be easier with the current implementation), or recur to some async strategies (e.g. allocate for each debugged session its own thread and stall that one instead of the eval thread). The second strategy would mean a more complicated instrumentation of def forms, like wrapping def's bodies into futures or async go blocks.
