0538233e2c Implement changes to make fix for NQNFS and MFS unmounting (race conditions) 
work. Not quite as good as with the Lite2 merges, but it'll do until then.

* dounmount() expects to be called with the mountpoint marked busy
* all callers of dounmount() thus make the call themselves
* if a filesystem was being unmounted, and we're woken up in vfs_busy(),
  don't reference the mountpoint struct pointer, as it has very probably
  been freed.

c745cba077 If the target for a rename() call exists, it will be removed. So, don't 
leave any pages around (i,e, insert a vnode_pager_uncache()).

  gratuitous casts.

53fccab940 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.

for them. There are a few #ifdef COMPAT_XX remaining, but they are not easy

fb371ccef0 tty_tb.c: need to include ioctl_compat.h in order to compile. 
sysv_shm.c: make shm_find_segment_by_shmid global so it can be used by
	    COMPAT_HPUX. There should be a better way...
rest: Add #ifdef COMPAT_HPUX where needed
