without corresponding number of fifo_open(). This causes assertion
failure in fifo_close() due to vp->v_fifoinfo being NULL for kernel
with INVARIANTS, or NULL pointer dereference otherwise. In fact, we may
ignore excess calls to fifo_close() without bad consequences.
Turn KASSERT() into the return, and print warning for now.

program name, and ignore that entry. ipfw2.c code instead skips
this entry and starts with options at offset 0, relying on a more
tolerant implementation of the library.
This change fixes the issue by always passing a program name
in the first entry to getopt. The motivation for this change
is to remove a potential compatibility issue should we use
a different getopt() implementation in the future.
No functional changes.

Note: this is only really necessary because of the ifconfig
logic to add/remove the jail IPs upon start/stop.
Consensus among simon and I is that the logic should
really be factored out from the startup script and put
into a proper management solution.
- We now support starting of no-IP jails.
- Remove the global jail_<jname>_netmask option as it is only
helpful to set netmasks/prefixes for the right address
family and per address.
- Implement jail_<jname>_ip options to support both
address familes with regard to ifconfig logic.
- Implement _multi<n> support suffix to the jail_<jname>_ip
option to configure additional addresses to avoid overlong,
unreadbale jail_<jname>_ip lines with lots of addresses.

Even though the code seems to be FreeBSD kernel code, it isn't compiled
on FreeBSD. I could have known this, because I was a little amazed that
I couldn't find a prototype of pfopen()/pfclose() somewhere else,
because it isn't marked as static.
Apart from that, removing these functions wouldn't have been harmful
anyway, because there are some other strange things about them (the
implementation isn't consistent with the prototype at the top). Still,
it's better to leave it, because it makes merging code back to older
branches a little harder.

It turns out I was patching functions that weren't used by pf(4) anyway.
They still seem to use `struct proc *' instead of `struct thread *'.
They weren't listed in pf_cdevsw.
Because it is not possible to access the pf(4) character device through
any other device node as the one in devfs, there is no need to check for
unknown device minor numbers.

an interpreter definition in its program header), set the auxiliary
ELF argument AT_BASE to 0 rather than to the address that we would
have mapped the interpreter at if there had been one.
The ELF ABI specifications appear to be ambiguous as to the desired
behavior in this situation, as they define AT_BASE as the base address
of the interpreter, but do not mention what to do if there is none.
On Solaris, AT_BASE will be set to the base address of the static
binary if there is no interpreter, and on Linux, AT_BASE is set to 0.
We go with the Linux semantics as they are of more immediate utility
and allow the early runtime environment to know that the kernel has
not mapped an interpreter, but because AT_PHDR points at the ELF
header for the running binary, it is still possible to retrieve all
required mapping information when the process starts should it be
required. Either approach would be preferable to our current behavior
of passing a pointer to an unmapped region of user memory as AT_BASE.

While noone normally notices this for the system shutdown, it helps for
cleanly shutting down trusted jails.

This is useful for cases such as NUMA or different layouts for the same
memory type.
- Provide a new api for adding new backend kegs to secondary zones.
- Provide a new flag for adjusting the layout of zones to stagger
allocations better across cache lines.
