Expandable \@testopt (and related) macros

The package provides an expandable variant of the LaTeX kernel command \@testopt, named \@expandable@testopt, and a more general \@expandable@ifopt, both intended for package writers. Also we have a variant of \newcommand which uses these macros to check for optional arguments.
