needed changes to get unpatched initscritps to work

[Robert Millan]

Hi,

Here's a description of the changes needed for initscripts to work without
patching (see http://glibc-bsd.alioth.debian.org/patches/sysvinit/03_hacks.diff
for details):

  dmesg: accept -s
  swap{on,off}: don't print anything to stdout
  mount: accept -n, -o remount
  umount: accept -r and -d, accept multiple mount points in one command

If someone is interested in hacking the stuff from freebsd-utils, I think these
should take priority so that we can start using sysvinit in unstable.

Note: Except for the umount ones, it's not important that the flags actualy
work.  Currently we're just removing them so it wouldn't make any difference.
