checK_paranoia.sh.in: fix bug in returning success on a core dump
win32.c: some small changes - more later.
image/*.c: set run_mmc_cmd NULL explicitly.
First paranoia regression test. It's run automatically as it assumes
that you have a *flawless* CD-DA in a drive.
*.{c,h}: more integration toward libcdio routines. In particular remove
swap16 and swap32.
