stdlib updates to take advantage of pointers

Browse Source 
The packed_{load,store}_active now functions take a pointer to a
location at which to start loading/storing, rather than an array
base and a uniform index.

Variants of the prefetch functions that take varying pointers 
are now available.

There are now variants of the various atomic functions that take
varying pointers (issue #112).
