Thanks autopsy!

Here's two patches.  The first one enables squashfs.  In order to use it
you invoke kadischi with the --filesystem option::

  kadischi --filesystem=squashfs fc5-repo fedora.iso

The patch makes te following changes:
* kadischi.py:
  - New option --filesystem=[compressed fs type]  This allows the ISO
creator to select zisofs or squashfs.
  - Bug fix: Change file variable to filename because file is a python
builtin.
  - Compress the filesystem to a squashfs image if --filesystem was set
to squashfs.
  - Do not pass -z to mkisofs if we aren't compressing a zisofs.
* livecd-mkinitrd.sh:
  - Create a /cdrom directory to mount the cdrom image to directly.
  - Copy squashfs and loop modules to the initrd.
  - Create loop[0-9] devices in the initrd.
* livecd-linuxrc:
  - Mount the cd image onto /cdrom instead of /sysroot.
  - If we're using squashfs, loopback mount it on /sysroot otherwise
bind mount the cdrom to /sysroot.

Note that I haven't tested zisofs output recently so it's possible I
broke zisofs creation since I started working on this.

The second patch is a collection of bugfixes of varying correctness:
* functions.py: import shutil as the cleanup() function uses it.
* install-boot.sh: Add selinux=0 to the kernel commandline as neither
squashfs nor zisofs support selinux xattrs.
* 04auth.sh: Comment out the lokkit call as this may not exist in the
install root.  The selinux portion of this call is taken care of by
adding selinux=0 to the kernel commandlin.  The firewall portion isn't.
And when we do add support for selinux the kernel commandline won't let
us choose between targetted/strict/other.  So the correct fix for this
needs more thought.
* 05fsclean.py: Code "copy this directory recursively" in python to
avoid calling rsync in the install root (which may not exist and thus
error out.)
* movefiles.py: Code a check for file existence before attempting to
move it.  This should never be reached but my initial kadischi runs were
triggering some bug here.  I haven't seen the diagnostic message
triggered recently so the bug may have gone back into hiding.

Let me know what you think,
