Just ignore the case where focus has more argument that planed as it has
been reported as an error earlier.
Also fix the error message for calling member function with the wrong
number of argument to not include the base in the count.
Fix#4883
Semi-random selection of clippy topics that were
uncontroversial before:-).
Leaves about 84 deduplicated issues in the code base
according to clippy from nightly.
Since commit 6fefe75a1c the handling
of forward-focus bindings happens before the resolve_expressions pass,
which means that we cannot rely on type mismatch
error handling yet.
Fixes#4475
Achieve this by generating a `focus()` function for such components
and call it from the outside.
This replaces the previous focus handling with what should be cleaner:
- Any `forward-focus: some-element;` is basically syntactic sugar for
`public function focus() { some-element.focus(); }`.
- The init code gets simplified to calling focus() on the root, if it's
available.
Since the `focus()` functions are now generated in the imports pass,
they become visible in the style checker. That means the checker
requires consistent focus handling between the styles.
