  Compose: add iterator API Allow users to iterate the entries in a compose table. This is useful for other projects which want programmable access to the sequences, without having to write their own parser. - New API: - `xkb_compose_table_entry_sequence`; - `xkb_compose_table_entry_keysym`; - `xkb_compose_table_entry_utf8`; - `xkb_compose_table_iterator_new`; - `xkb_compose_table_iterator_free`; - `xkb_compose_table_iterator_next`. - Add tests in `test/compose.c`. - Add benchmark for compose traversal. - `tools/compose.c`: - Print entries instead of just validating them. - Add `--file` option. - TODO: make this tool part of the xkbcli commands.
