Updated free list interface

I realized my existing interface wouldn't work
if the coalescing or adding of a new node replaced
the head of the list, as there was no way to
communicate that back to the caller. As a result,
I've updated those interfaces to accept a pointer
to the free list head pointer. This will let them
change the free list head in alloc.c if necessary.
