Convert everything to use negative error codes. The caller treats all non-zero returns the same so this does not affect run time. A couple places set "rc" instead of "status" so those error paths ended up returning success by mistake. Get rid of the "rc" variable and use "status" everywhere. Remove the bogus "status = 0" initialization, as a future proofing measure so the compiler will warn about uninitialized error codes.
