d383612450 Add some info to config.mk
glibc breaks tools on 32bit systems due to a design flaw not allowing
64bit file offsets and only doing so with a cryptic flag.

Also, make sure to tell users about -lrt, which might be needed on
some systems.

198c45ee6d Remove col(1)
Where should I start? It's a rather irrelevant tool and broken as is.
We'll re-add it as soon as the code has been fixed by the original
author.
Until then, better keep it out or some kids get hurt.

93043beec9 readlink: simplify -f
Use output from realpath(3) directly. This makes usage
with . more consistent with other implementations.

ced76f3b03 sed: support extended regular expressions (-E)
Not specified in POSIX.1-2008.
GNU sed uses -r, openbsd uses -E but aliases -r to -E for compat.

78b285deb6 Fix ln(1) symbolic link handling
This was broken in multiple ways. For instance, the overlay-
check of identical files (name and target) was omitted for
symbolic links for some reason.
While at it, I fixed the stat-handling, improved the error-
messages so the right paths were shown and removed the
illegimite bail-out when the target-fstatat failed (we want
only a warning here as well).

d23cc72490 Simplify return & fshut() logic
Get rid of the !!()-constructs and use ret where available (or introduce it).

In some cases, there would be an "abort" on the first fshut-error, but we want
to close all files and report all warnings and then quit, not just the warning
for the first file.

e8a4f37884 Fix tail(1) -n 0 handling and unglobalize some variables
Don't terminate too early. If the given file doesn't exist,
we need the error-message.

Additionally, some variables were globals for no good reason.

1797df01e7 Fix uniq(1)
The argument handling was quite garbled up. So I fixed it.
In the process, it drops a lot of locs.

Previously, it would lead to an off-by-one in an edge case, so
stop messing around with argv and use an idiomatic fp- and fname-
array.

Now this works fine and is much easier to read.

This is also the first step towards going back to strcmp() instead
of handrolling the "-"-checks.

1d28fbd6cf mv, cp: Preserve nanosecond timestamps
Otherwise, we run into problems in a typical autoconf-based build
system:

  - config.status is created at some point between two seconds.
  - config.status is run, generating Makefile by first writing to a file
    in /tmp, and then mv-ing it to Makefile.
  - If this mv happens before the beginning of the next second, Makefile
    will be created with the same tv_sec as config.status, but with
    tv_nsec = 0.
  - When make runs, it sees that Makefile is older than config.status,
    and re-runs config.status to generate Makefile.

0545d32ce9 Handle '-' consistently
In general, POSIX does not define /dev/std{in, out, err} because it
does not want to depend on the dev-filesystem.
For utilities, it thus introduced the '-'-keyword to denote standard
input (and output in some cases) and the programs have to deal with
it accordingly.

Sadly, the design of many tools doesn't allow strict shell-redirections
and many scripts don't even use this feature when possible.

Thus, we made the decision to implement it consistently across all
tools where it makes sense (namely those which read files).

Along the way, I spotted some behavioural bugs in libutil/crypt.c and
others where it was forgotten to fshut the files after use.

- add -p dir, -t and -u.
- fix dirname(tmp) check (did not check null terminator).

the semantics of mktemp is now the same as OpenBSD mktemp.

8f4b2e8689 ln: only check existence of src/to for hardlinks
This allows for creating dangling symlinks with force applied:

    # Before:
    $ ln -sf non-existant target
    ln: stat non-existent: No such file or directory
    $ ls -l target
    ls: lstat target: No such file or directory

    # After:
    $ ln -sf non-existant target
    $ ls -l target
    lrwxrwxrwx    1 eu    users   12 May 08 07:50 target -> non-existent

This also allows creating relative non-dangling symlinks with force applied:

    touch existant; mkdir dir

    # Before
    $ ln -sf ../existant dir
    ln: stat ../existant: No such file or directory
    $ ls -l dir

    # After
    $ ln -sf ../existant dir
    $ ls -l dir
    lrwxrwxrwx    1 eu    users   11 May 08 07:53 existant -> ../existant

The check for whether each src and to pairs are on the same device with the
same inode are only needed for hardlinks so that a forcefull link does
not remove the underlying file:

    touch f; mkdir dir

    # Before:
    $ ln -f f f dir
    ln: f and f are the same file
    $ ls -i f dir/f
    3670611 dir/f
    3670611 f

    # After:
    $ ln -f f f dir
    ln: f and f are the same file
    $ ls -i f dir/f
    4332236 dir/f
    4332236 f
