Fill in vnodecovered in the mount structure before calling VFS_MOUNT anyway,

some things (e.g. unionfs) may depend on it. It's currently ok
for vnodecovered to be set already; it's not for v_mountedhere in
the vnode, though.
From John Darrow.
XXX should probably just extend VFS_MOUNT to take the vnode pointer as
an argument.

Use a SETRECURSE lock before calling VFS_MOUNT in the mount() system call,

since the lock may be taken again. This was the intention of the CANRECURSE
lock already there, but didn't work.
Only fill in the vnode<->mountpoint links (mountedhere and vnodecovered)
after VFS_MOUNT returned succesfully. It might happen that something called
from VFS_MOUNT mistook the vnode for an already successfully mounted on
one because of this.

readlink() from type `int' to type `size_t'. This isn't an ABI change, since

this argument to a `long'.
This may not be the final action on this matter; readlink() still returns
an `int', which may change in a future revision of the standard.

change_owner().
* Change the semantics of chown(), fchown() and lchown(): when requesting a
change of the owner of a file, clear the set-user-id bit; analogous behaviour
for group changes.
* Since the above is a violation of the semantics specified by POSIX and
X/Open, add corresponding compatibility syscalls: __posix_chown(),
__posix_fchown(), __posix_lchown(). (Neither fchown() nor lchown() is
specified by POSIX; the prefix is intended to reflect the semantics.)
* Rename posix_rename() to __posix_rename() to follow the above convention.
