c562063980 Some implementations of getopt() expect that argv[0] is always the
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.

8154af81ff Update jail startup script for multi-IPv4/v6/no-IP jails.
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.

4c6a60218c Rewrite of MI strlen(3) in a way that can better utilize modern hardware by

The idea is taken from J.T. Conklin's x86_64 optimized version of strlen(3)

55b043392b Revert my previous two changes.
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.

95c807cf5e When a statically linked binary is executed (or at least, one without
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.

7bc5585ecb Instead of killing the 'watchdog' subshell and leaving a sleep for
rcshutdown_timeout (normally 30s) around re-parented to init, make
sure both go away using pkill -P.

While noone normally notices this for the system shutdown, it helps for
cleanly shutting down trusted jails.
Found without a killall in the base system, which in rc.d/jail normally
ensures that all processes of a jail to be stopped will be killed.

0d2cf8374a - Use __XSTRING where I want the define to be expanded. This resulted in

8d9b29f35b If the parent up/down task was queued then sync with it before returning from

11b763df19 Fix errors introduced when I rewrote select.
- Restructure selscan() and selrescan() to avoid producing extra selfps
   when we have a fd in multiple sets.  As described below multiple selfps
   may still exist for other reasons.
 - Make selrescan() tolerate multiple selfds for a given descriptor
   set since sockets use two selinfos per fd.  If an event on each selinfo
   fires selrescan() will see the descriptor twice.  This could result in
   select() returning 2x the number of fds actually existing in fd sets.

91dd9aae1a Add explicit static DTrace tracing to the callout mechanism, capturing
pointers to the callout handler just before and just after the callout
it invoked.  I attempted to do this in a manner congruent to tracing in
Solaris's callout mechanism, but couldn't quite use the same names due
to convention and syntax differences.

Example DTrace script to generate a distribution graph of callout
execution times:

callout_execute:::callout_start
{
        self->cstart = timestamp;
}

callout_execute:::callout_end
{

        @length = quantize(timestamp - self->cstart);
}
