libsysprof-analyze: add sysprof_document_list_symbols_in_traceable()

Browse Source 
This function will list the symbols in a traceable in a way that is
suitable for showing in a GtkListView or GtkColumnView. For example, that
requires creating copies of the symbols so that duplicates do not cause
hickups with GtkListItemManager.
