a) a widget's nid is always it's index in the codec's widget list.

b) members of the widget connection list may be invalid.
so,
- change azalia_nid_to_index to azalia_widget_enabled, and have it only
check that the given nid is valid, and that the corresponding widget
is enabled.
- use azalia_widget_enabled every time members of the connection list
are used.
