> Extend the C code generator to support more DFDL features such as
> arrays with occursCountKind="expression" and padding variable length
> elements to multiples of 4 bytes by following them with alignment="4"
> elements.  Currently the generator handles only finite inlined arrays,
> not unbounded arrays or arrays with dynamically allocated memory.  An
> array's declaration always uses its maxOccurs attribute as its size
> and uses that same amount of static memory space regardless of how
> many values the data file actually puts into the array element.
> Note the new support for padding variable length elements is
> rudimentary, barely handles even my specific alignment="4" use case,
> and needs reviewer suggestions to improve it.
