Improved split for symmetric tensor functions.
Currently, a mixed element with symmetric tensor
subelement counts the complete value shape of
the subelement (not accounting for symmetries)
towards its total value size. But split will
use the symmetry mapping when indexing the
mixed function to get sub function components,
so you get sub functions like [[w0, w1], [w1, w3]].

Bugfixes:
- validate_form uses form.form_data().form instead of calling expand_indices, avoiding possible duplicate calls to this.
- extract_arguments checks for duplicate argument counts.
- lhs produced "u*v*dx + 0*ds" from "u*v*dx + g*ds"
