Uri.getQueryTable

Get the query table from the URI. Keys and values in the table are freed with g_free when they are deleted. A value may be null to indicate that the key should appear in the query string in the URI, but does not have a value. Free the returned #GHashTable with #[glib.hash_table.HashTable.unref] when it is no longer required. Modifying this hash table will modify the query in the URI.
