program_loading: Replace prog_rdev() with raw start pointer and size
Since prog_locate() was eliminated, prog_rdev() only ever represents the
loaded program in memory now. Using the rdev API for this is unnecessary
if we know that the "device" is always just memory. This patch changes
it to be represented by a simple pointer and size. Since some code still
really wants this to be an rdev, introduce a prog_chain_rdev() helper to
translate back to that if necessary.
