Debugger Changes

• The meaning of the goal(G) breakpoint test has changed: it succeeds if the current goal is an instance of G, instead of checking if the current goal unifies with G. Similarly for the ancestor(A) test.
• Any variable instantiations introduced in the evaluation of the test part are undone before executing the action part.
• The parent_pred/[1,2] tests perform module name expansion on their first argument.
• The proceed/2 and flit/2 commands are allowed at non-call ports, too; their module name expansion rules have changed.
• current_breakpoint/4 is changed to current_breakpoint/5. It now returns the breakpoint conditions in exactly the same form as given to add_breakpoint/2.
• The interpretation of the first argument of execution_state/2 has changed; the order of list elements does not matter any more.
• The new get condition allows to access action variables from within the action part.
• Test exited/1 replaces test last_port/1.
• A breakpoint condition can be a variable at add_breakpoint time, as long as this variable gets instantiated by evaluation time.
• Breakpoint macros are expanded at add_breakpoint time, rather than during evaluation.
• It is not possible any more to redefine a built-in breakpoint condition using the breakpoint expansion mechanism.
