This map is never cleared.

Done.

SourceMappingChanged event is definitely not something that belongs to
uiSourceCode anymore. It should be moved to DebuggerWorkspaceBinding where a
method like addSourceMappingChangedListener(uiSourceCode) should be added.
I am fine with doing this in a separate patch though, as this seems quite
independent to other changes in this patch.
