Log Message:
Take care of six more mallocs:

- Pull rf_FreePhysDiskAddr() out from under a #ifdef, since we're now
going to use it.

- Add a pda_cleanup_list into the DAG header.  Use it in rf_FreeDAG() to
cleanup any PDA's that get allocated but have no "easy" way of being
located and freed when the DAG completes.

- numStripeUnitsAccessed is a per-stripe value, and has a maximum
value equal to the number of colums (thus limited by RF_MAXCOL).
Use this knowledge to set a high-bound on overlappingPDAs, and stuff
it on the stack instead of malloc'ing it all the time!  This costs us
a whopping 40 bytes on the stack, but saves a malloc() and a free().
