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.
