90688fce27 Change the second and third args to struct vfsops' (*vfs_mount)() to 
'const char *', and 'void *', respectively.  The second arg is taken directly
from user arguments, and is const there, so must be const in the prototypes
and functions.  The third arg is also taken directly from user arguments.
It doesn't have to be changed, but since it's cleaner to keep the type
the same as the user arg's type, and I'm already making the 'const char *'
change...

a67c0b16b8 define path name string variables that we should not (and, thankfully, do 
not) modify as 'const char *' rather 'char *'.

6ddae4d140 Implement proper `..' locking in lookup code to avoid many potential 
deadlocks.

copy up properly when adding a link to lower-layer only file.
(I believe there are still more deadlocks remaining.)

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.
