in stopped state. Add helper for executing calls
to ExtensionContext including recording of output in
OutputCallback. Extend symbol resolution to return addresses
as well since QApplication::widgetAt() is ambiguous and needs
to be called by address. Add 'widgetat' extension command
to return the widget.
- Move the 'current module' into the Node
- Split symbol group hierarchy into LocalsSymbolGroup
tied to frame/thread and a separate, scopeless
WatchesSymbolGroup
- Add infrastructure for removing symbols from a SymbolGroup,
doing the index bookkeeping.
- Add method to synchronize watches to WatchesSymbolGroup
(iname/name map).
- Introduce watches commands for adding and dumping.
- Extend locals command to get watches as well.
- Add a dummy 'ErrorSymbolGroupNode' to use in case
insertion fails.
