paging stats. Fixed problem with free_reserved becoming depleted during
certain swap_pager operations.

This puppy is in good shape now.
It is a fully blown SCSI-driver, but it isn't a high performance one. It is
implemented entirely with polled I/O, and is intended to drive CD-ROM's, not
disks and tapes. It will run disks and tapes if asked to, but it isn't a
very good idea to do so. Transfer-rates max out at 600-700 kbyte/sec.
There is one problem: when write-requests get over 8192 bytes, the pseudo-DMA
stalls. This is only a problem if you dd(1) to a raw-device of some kind,
for mounting a disk it is ok. I have circumvented this by disabling the
pseudo-DMA in those cases.
It's very unlikely that I will spend more time on improving the performance
of this driver, it can do what I want it to now: install from a CD-ROM, and I
don't see any benefit in actually adding interrupts to the driver, considering
that performance never will be better than 700 kbyte/sec anyway.
You can install it under 1.1.5 too, by adding the lines to files.i386, your
config-file and copying pas.c and ic/ncr_5380.h over.
I will fix any bugs I can get a handle on.

- make sure error messages for bad integers are moderately sensible
- handle test ! "abc" -o "abc" (This should evaluate to true)
(and similar cases) ie:
and/or operator test added to POSIX special case processing.
- more test cases added.
Based on: Work done on 1.x's test(1) by Andrew Moore and Adam David.
otherwise the machine will overflow the stack in a recursive fault loop
(causing the machine to spontaneously reboot because of the stack fault
that ultimately happens).
Submitted by: Inspired by Bruce Evans, but this change is different
than what he suggested.

These are the FAQ files, reorganized a bit and updated marginally for 2.0.
There is *still more work to be done* in updating, so if some of your FAQ text
is below, please check it over! We've also got a lot of FAQ entries still
to write (examples: "how do I upgrade?" "what's new in 2.0?" "how do I
install on a notebook/second drive/from DOS/etc etc etc?"
1. DISTFILE is gone and replaced by DISTFILES, which can contain one or
more file specifications.
2. MASTER_SITE created, which points to the distfiles directory on
freebsd.cdrom.com (which I'll set up in a moment).
3. HOME_LOCATION is now simply a hint, and is never directly used except
to inform the user when ncftp unable to transfer a file from
MASTER_SITE.
4. ncftp is now assumed to live somewhere in the path, in preparation for
Andrew bringing it in on a more permanant basis.
5. XMKMF defined - it was not before.
Thanks to Andrew (ache) for many helpful suggestions.
