 Purpose:  
 
 With variable objects, the value of array elements and structure members must
 be accessed individually (using the MI command -var-evaluate-expression). This
 means that a front end can take too long processing a separate MI command for
 each element/member. This patch adapts the MI command -var-list-children so
 that all the values can be accessed at once allowing the display of an array
 or structure to be expanded rapidly (in the style of Insight or Visual
 Studio).  The existing behaviour of -var-list-children is preserved of backward
 compatibility.
