patch v2


This is a new version of the patch. It eliminates the remaining corner case
where C_TYPE_VARIABLY_SIZE was not fully defined by the basic properties of the
type, i.e. unspecified sizes as 'int foo(int x[*])'.  The idea to represent
them with a type domain that makes them automatically be understood as a VLA.
This also another old issue where the old representation was causing them to be
printed as [0].
