8360efbd6c Bring in a hybrid of SunSoft's transport-independent RPC (TI-RPC) and
associated changes that had to happen to make this possible as well as
bugs fixed along the way.

  Bring in required TLI library routines to support this.

  Since we don't support TLI we've essentially copied what NetBSD
  has done, adding a thin layer to emulate direct the TLI calls
  into BSD socket calls.

  This is mostly from Sun's tirpc release that was made in 1994,
  however some fixes were backported from the 1999 release (supposedly
  only made available after this porting effort was underway).

  The submitter has agreed to continue on and bring us up to the
  1999 release.

  Several key features are introduced with this update:
    Client calls are thread safe. (1999 code has server side thread
    safe)
    Updated, a more modern interface.

  Many userland updates were done to bring the code up to par with
  the recent RPC API.

  There is an update to the pthreads library, a function
  pthread_main_np() was added to emulate a function of Sun's threads
  library.

  While we're at it, bring in NetBSD's lockd, it's been far too
  long of a wait.

  New rpcbind(8) replaces portmap(8) (supporting communication over
  an authenticated Unix-domain socket, and by default only allowing
  set and unset requests over that channel). It's much more secure
  than the old portmapper.

  Umount(8), mountd(8), mount_nfs(8), nfsd(8) have also been upgraded
  to support TI-RPC and to support IPV6.

  Umount(8) is also fixed to unmount pathnames longer than 80 chars,
  which are currently truncated by the Kernel statfs structure.

81667275a9 Don't warn about unknown mount types, since they most likely simply mean
that the right module hasn't been loaded yet (and mount(8) will do so
when necessary).

a69497d73f Finish up umntall support. init now passed an argument to the
rundown script 'reboot' or 'single'.  ISO support (which never
    worked) has been removed from mount_nfs.  mount_nfs and umount
    now use mounttab, which allows umntall to work properly.  The
    rc scripts now call umntall as appropriate.

bc70c1725f quoting << Martin_Blapp
-	Completly changed the internals of umount(8). We do three
	checks now to see if 'argv' is in the mounttable. It they
	all fail, we return to main and print a warning.

-	fixed the umount mount-order. The checks are rather complex
	to do this. Cause umount(8) should also be able to unmount
	several devices at once ('umount -a', 'umount -A',
	'umount /mnt /mnt2'), the mount-order get's important.
	I added checks to mark and unmark already unmounted devices.

- 	Various fixes with nfs-unmounts (no rpc-calls were done,
	or they were done although there was an existing mount).
	Since we allow overlay-mounts, we should also handle them
	properly.

-	Translate the deprecated nfs-syntax with '@' to ':' like
	mount_nfs does. The ':' syntax has now precedence, but '@'
	still works.

-	'umount -v' is now fixed for all cases and doesn't print
	garbage like two times the mountpoint etc.

-	removed non documented and useless umount '-F'.

-	hanged nfsmounts can now unmounted 'without' any problems.
	I've removed stat() and realpath() checks on the mountpoint.
	Instead we just do a realpath() on the basedir of the
	mountpath and add the dirname again.
	Implemented this as an idea from phk. But there are still
	vfs-restrictions if the nfs_mount is busy. If there are
	unwritten metadata on a hanged nfs-mount, and we modify
	nfs_vfsops.c to not return EBUSY, we get a deadlock :(
	The problem has now moved from userland to kernel.

-	removed the BUGS part from the umount(8) manpage.

-	Converted it to ANSI C (more than 60% of the code have
	changed).

428fb2dd11 Fix PR 1607, hopefully without breaking the PR 5208 fixes.
umount() was trying to stat() the mountpoint, this would fail if the
mountpoint was a NFS mountpoint, and the fallback code would try and pass
a hostname:/dir path as the mountpoint to unmount(2), which would fail.

This whole stat() of the name supplied on the command line business is
trouble as it'll wedge on a hung NFS mount.

I'm not entirely sure why we are not simply looking up both arguments
in the mount table and doing the right thing without accessing the
filesystem.  It seems that we're going to a lot of trouble to allow
mountpoints on symlinks and other wierd things.

82000ec41c Fixed the previous fix. The original path was annulled when it
was a directory, so the error message for attempting to unmount
an unmounted-on directory was more broken than before.

bd4f43ff72 mount(8) only uses realpath() for the mountpoint, so don't look up the
real path here for the mount device (or path).  This fixes difficulties
unmounting devices that are actually symlinks to real devices.

Also, print the original path instead of the real path in early error
messages.  nfs path handling and later error messages may still be wrong,
probably only in silly cases where the original path is both a symlink
and a remote path.

d499a0ef65 Merge from Lite2.
- use new getvfsbyname() interface.
- new -A option, like -a except only mounted file systems are unmounted.

All non-cosmetic FreeBSD changes in umount.c, except ignoring of
realpath() failures, went away because they are done better in Lite2.
realpath() failures must be ignored so that non-pathnames like
"<above>:/foo" and "host:/bar" get as far as mount(2).

5974081cea From njw@cs.city.ac.uk (Nick Williams):
/sbin/umount does not return the correct exit status due to incorrect
logic in its internals.

Further, because of the nature of the code, you *cannot* use it to
umount a directory from a union mountpoint. Well, you can sometimes,
it depends on if the directory is at the top of the union stack or not :)
