717a08b6e5 Replace our test(1) with NetBSD's pdksh-derived version. The code is
significantly easier to read and extend and offers a few new tests.
A few style changes taken from style(9) and OpenBSD, as well as
whitespace cleanups.

This change was discussed on freebsd-committers and freebsd-hackers
and met with approval from at least des, eivind and brian.

MFC-jockies should make sure that bde's concerns regarding the number

3bc1b1bb27 the month and three days are up for -hackers and the 24hrs for -committers.
add a -j flag that tells date not to try to set the date.  This allows you
to use date as a userland interface to strptime.

example:
TZ=GMT date -j -f "%a, %d %b %Y %T %Z" "Sun, 08 Nov 1998 02:22:20 GMT" +%s

which is the standard format for Last-modified headers in HTTP requests.

75c1354190 This Implements the mumbled about "Jail" feature.
This is a seriously beefed up chroot kind of thing.  The process
is jailed along the same lines as a chroot does it, but with
additional tough restrictions imposed on what the superuser can do.

For all I know, it is safe to hand over the root bit inside a
prison to the customer living in that prison, this is what
it was developed for in fact:  "real virtual servers".

Each prison has an ip number associated with it, which all IP
communications will be coerced to use and each prison has its own
hostname.

Needless to say, you need more RAM this way, but the advantage is
that each customer can run their own particular version of apache
and not stomp on the toes of their neighbors.

It generally does what one would expect, but setting up a jail
still takes a little knowledge.

A few notes:

   I have no scripts for setting up a jail, don't ask me for them.

   The IP number should be an alias on one of the interfaces.

   mount a /proc in each jail, it will make ps more useable.

   /proc/<pid>/status tells the hostname of the prison for
   jailed processes.

   Quotas are only sensible if you have a mountpoint per prison.

   There are no privisions for stopping resource-hogging.

   Some "#ifdef INET" and similar may be missing (send patches!)

If somebody wants to take it from here and develop it into
more of a "virtual machine" they should be most welcome!

Tools, comments, patches & documentation most welcome.

Have fun...

bb22740673 On FreeBSD/alpha, ps(1) does not correctly report process start times
and CPU runtime because it can't access the user area via /proc/<pid>/mem.
This is because the uarea is not mapped into the process address space
at USRSTACK on the alpha like it is on the x86.

Since I'm haven't been able to wrap my brain around the VM system enough
to be able to figure out how to achieve this mapping, and since it's
questionable that such an architectural change is correct, I implemented
a workaround to allow ps(1) to read the uarea from /dev/kmem using
kvm_read() instead of from the process address space via kvm_uread().
The kludge is hidden inside #ifdef __alpha__/#endif so as not to impact
the x86. (Note that top(1) probably uses this same gimmick since it works
on FreeBSD/alpha.)
