Update the error handling in a couple of cases to exit gracefully if
certain mandatory conditions aren't met.
Reduce the maximum number of initiators to 8 for this example code. While
1024 is more correct, this example code would act like it was stalled out
even though it was merely allocating the needed structures in init_ccbs()

we will fail to unmount it, but it won't be removed from the tree,
so in that case there is no need to reinsert it.
This fixes a panic reproducable in the following steps:
# zfs create tank/foo
# zfs snapshot tank/foo@snap
# cd /tank/foo/.zfs/snapshot/snap
# umount /tank/foo
panic: avl_find() succeeded inside avl_add()

with packages on the release media. It looks like we'll be putting just
the doc packages on the new "memory stick" image as well as disc1. There
will be no other packages on the CDROM-sized media. The DVD sized media
will include the doc packages plus whatever other packages we decide to
make part of the release.
This commit just brings the basic structure in line with being able to
do this. We still need to discuss with various people exactly which
packages will be included on the DVD.
If the environement variable "PKG_DVD" is set a tree suitable for the
DVD media is generated. Otherwise a tree suitable for the "memory stick"
and disc1 is generated.

does a KASSERT that the group address is multicast, so the
check if this is indeed true and eventually return a EINVAL if not,
should be done before calling inp_lookup_mcast_ifp. This fixes a kernel
crash when calling setsockopt (sock, IPPROTO_IP, IP_ADD_MEMBERSHIP,...)
with invalid group address.

never been inserted into the pfs_vncache list. Since pfs_vncache_free()
does not anticipate this case, it decrements pfs_vncache_entries
unconditionally; if the vnode was not in the list, pfs_vncache_entries
will no longer reflect the actual number of list entries. This may cause
size of the cache to exceed the configured maximum. It may also trigger
a panic during module unload or system shutdown.
Do not decrement pfs_vncache_entries for the vnode that was not in the
list.

Now that pty(4) is a loadable kernel module, I'd better move /dev/ptmx
in there as well. This means that pty(4) now provides almost all
pseudo-terminal compatibility code. This means it's very easy to test
whether applications use the proper library interfaces when allocating
pseudo-terminals (namely posix_openpt and openpty).
