6e8ba625ef Ignore the mountpoint's `v_usecount' in nfs_unmount() if MNT_FORCE is on. 
This takes care of two related problems:
	- `umount -f' wouldn't work if someone's working directory is
	  the filesystem root.
	- vfs_unmountall() would complain about a busy `/' on a
	  diskless setup.

d9d0cc229c fix two bugs (the latter potentially fatal) in xdr_string_encode(): 
(1) if length needed was > MCLBYTES, an mbuf would be lost, and
(2) the wrong check was being used to determine if MCLGET succeeded.

XXX There is no clean solution to the cookie/cookieverifier validity mess.
    Together with the disabled strict cookie check, this puts us back at
    what v2 did in this case. Slightly better solution possible by
    consequently storing 64bit cookies in other places too.

c9c8301a91 Fix vop_link, vop_symlink, and vop_remove semantics in several ways: 
* Change the argument names to vop_link so they actually make sense.
* Implement vop_link and vop_symlink for all file systems, so they do proper
  cleanup.
* Require the file system to decide whether or not linking and unlinking of
  directories is allowed, and disable it for all current file systems.
(Also, remove the cross-device link check, that was moved into the file
systems some time ago.)

d61f235615 Add cookie support. Stash cookies in the word prior to the end of 
each entry, and read them out in nfs_readdir().

Caveat: our current caching method for directory blocks uses the
server offset of the first directory entry as an identifier, so a
Linux emulation getdirentries() will wind up retrieving one block from
the NFS server for each directory entry, unnecessarily thrashing the
cache.  The situation isn't as bad for other emulations.

Instead of getblk(), we need to write a routine to scan each cache
block associated with vp to find a cookie that matches at some
directory entry.  Some later time.

f7003b8eba blow away all vestiges of nfsnode locking. 
(1) it's unnecessary
	(2) it causes machines to hang (yup!)
	(3) it'd be gone in a few days anyway (it'd been yanked out
		of 4.4-Lite by macklem long ago)
It was only there because macklem couldn't originally decide if things
should be locked, or not...

489bece05f be more intelligent with credentials, so nfsd's don't inherit 
strange credentials.  This doesn't actually have any effect on
performance, because the remote cred is used for all operations,
anyway.  however, it makes "ps" et al. look normal, because the
proc's ucred is no longer clobbered.
