09152a86ff Add a description of the restrictions that red(1) imposes to users, 
and a warning that this "restricted mode" can be bypassed easily by
using symlinks, so that users don't depend too much on it.

41623b2d75 Don't try to decode old-style options if the argv[1] begins with `-' and the 
second character represents some option taking an argument. This fixes
problem when ps(1) is invoked for examply as follows:

$ ps -Ufoobar1234

the above example results in option string being interpreted as
-U foobarp1234 - note extra `p'.

49d54362f1 Bogusness may have happened using a variable assignment here before, but 
proper parens mean that fd is always set by open(2) [in any part of C],
and so we can accurately check for it returning -1, without feeling like
we need to initialise fd to -1 in its declaration.

In other words, fix a stylistic/bogus nit.

52183d0145 Add uuidgen(2) and uuidgen(1). 
The uuidgen command, by means of the uuidgen syscall, generates one
or more Universally Unique Identifiers compatible with OSF/DCE 1.1
version 1 UUIDs.

From the Perforce logs (change 11995):

Round of cleanups:
o  Give uuidgen() the correct prototype in syscalls.master
o  Define struct uuid according to DCE 1.1 in sys/uuid.h
o  Use struct uuid instead of uuid_t. The latter is defined
   in sys/uuid.h but should not be used in kernel land.
o  Add snprintf_uuid(), printf_uuid() and sbuf_printf_uuid()
   to kern_uuid.c for use in the kernel (currently geom_gpt.c).
o  Rename the non-standard struct uuid in kern/kern_uuid.c
   to struct uuid_private and give it a slightly better definition
   for better byte-order handling. See below.
o  In sys/gpt.h, fix the broken uuid definitions to match the now
   compliant struct uuid definition. See below.
o  In usr.bin/uuidgen/uuidgen.c catch up with struct uuid change.

A note about byte-order:
        The standard failed to provide a non-conflicting and
unambiguous definition for the binary representation. My initial
implementation always wrote the timestamp as a 64-bit little-endian
(2s-complement) integral. The clock sequence was always written
as a 16-bit big-endian (2s-complement) integral. After a good
nights sleep and couple of Pan Galactic Gargle Blasters (not
necessarily in that order :-) I reread the spec and came to the
conclusion that the time fields are always written in the native
by order, provided the the low, mid and hi chopping still occurs.
The spec mentions that you "might need to swap bytes if you talk
to a machine that has a different byte-order". The clock sequence
is always written in big-endian order (as is the IEEE 802 address)
because its division is resulting in bytes, making the ordering
unambiguous.

532aff98f6 Remove the private code for reading UFS superblocks, this does not belong 
in df(1) when we have multiple filesystem types, and the complications of
handling UFS2 pushes this over the edge.

Use the .../mount/extern.h to get prototypes of the functions we
borrow from there.  Constify things to match.  (why aren't these
functions in a lib anyway ?)

Make everything static and set WARNS?=5.

The way the "df diskdevice" thing works for unmounted diskdevices
is not very general.

- If an argument cannot be *completely* converted to an integer, then
it is a string.
