vectors; defer that to vfs_opv_init().
Change the interface to vfs_opv_init() and export it; it now takes a
pointer to an array of vnodeopv_desc *'s to initialize. Allocate
the vnode operations vectors here. Called by vfs_attach().
Implement vfs_opv_free(), which deallocates the vnode operations
vectors. Called by vfs_detach().
Change vfsinit() to build the initial vfs_list by traversing the
vfs_list_inital[] table, and vfs_attach()'ing those file systems.
Also, initialize special vnodeopv_descs (dead, fifo, spec) which
are not associated with any particular file system.
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.
(thus causing s_leader to become NULL) by storing the session ID separately
in the session structure. Export the session ID to userspace in the
eproc structure.

UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code. i provided some help
getting swap and paging working, and other bug fixes/ideas. chuck
silvers <chuq@chuq.com> also provided some other fixes.
this is the rest of the MI portion changes.
this will be KNF'd shortly. :-)
down "Data modified on freelist" and "muliple free" problems.
The log is activated by the MALLOCLOG option, and the size of the
event ring buffer is controlable via the MALLOGLOGSIZE option (default
is 100000 entries).
From Chris Demetriou, cleaned up a little by me per suggestions in the
e-mail from Chris that contained the code.
