More -Wmissing-variable-declarations fixes.

In addition to adding `static' where possible:

- bin/date: Move `retval' into extern.h to make it visible to date.c.
- bin/ed: Move globally used variables into ed.h.
- sbin/camcontrol: Move `verbose' into camcontrol.h and fix shadow warnings.
- usr.bin/calendar: Remove unneeded variables.
- usr.bin/chat: Make `line' local instead of global.
- usr.bin/elfdump: Comment out unneeded function.
- usr.bin/rlogin: Use _Noreturn instead of __dead2.
- usr.bin/tset: Pull `Ospeed' into extern.h.
- usr.sbin/mfiutil: Put global variables in mfiutil.h.
- usr.sbin/pkg: Remove unused `os_corres'.
- usr.sbin/quotaon, usr.sbin/repquota: Remove unused `qfname'.

Synthesize the change from NetBSD's 1.33:

"Do not crash if a date cannot be represented (localtime returning
NULL), use the Epoch value instead."

Obtained from: njoly@NetBSD.org

Bring in the relevant changes from NetBSD's 1.31:

"Use strlcpy, not strncpy, when the desired semantics are strlcpy's
rather than strncpy's."

Note: NetBSD's 1.32 is their adoption of our r216206

Obtained from: dholland@NetBSD.org

Bring in the change from OpenBSD's 1.14:

"synchronize synopsis and usage; "-l", "-r", "-s" and "-x" are mutually
exclusive; while here, slightly improve spacing in the source code
so it fits on a 80-column display again.

Bring in the following changes from NetBSD. See the discussion at:
http://gnats.netbsd.org/cgi-bin/query-pr-single.pl?number=44128

1.29
"Don't printf time_t with %d; fixes PR 44128 from yamt. With this change it
successfully prints mtimes after 2038."

1.30
"Improve previous with comments."

Obtained from: dholland@NetBSD.org (both)

Fix an "unused variable" error that gets us all the way to WARNS=6

Bring in the update from NetBSD 1.28:

"Fix WARNS=4 issues (-Wcast-qual -Wsign-compare)"

Because of code differences I had to hand-apply parts of the patch,
so responsibility for errors goes to me.

Obtained from: lukem@NetBSD.org

Bring in a new feature, adding a -f option to readlink to print the path
of the target, similar to realpath(1). See the discussion at:
http://gnats.netbsd.org/cgi-bin/query-pr-single.pl?number=34662

This brings in the following changes:
1.24
"PR/34662: martijnb at atlas dot ipv6 dot stack dot nl: readlink doesn't
grok -f, and there's no alternative (+fix)

Patch applied with minor tweak (%y -> %R, as it was already taken) plus
some nits from myself. Thanks!"

Obtained from: elad@NetBSD.org

1.25
"Fix a segfault when doing 'stat -f %R' on the stdin file handle, instead
fake the filename '(stdin)' like the %N format."

Obtained from: mlelstv@NetBSD.org

1.27
"The ofmt variable is actually a bit mask (not the character that was
in the format string) so that we can "or" it with the bits in the
formats variable. This fixes the missing " -> " in front of the real
path (when you use %SR).

Also, the ?: needs another space."

I am purposely omitting the following changes:
1.23 A humanize_number(3) clone that should better be implemented by
actually using humanize_number(3)
1.26 This is the removal of license clause 3 and 4, already handled
by imp in r203971

Bring in the change from NetBSD 1.22:

"Fix a trivial truncation case, and eliminate a corner case that might
print a nul character."

I am purposely bypassing the following versions:
1.19 A build infrastructure change that does not apply to us
1.20 A feature I am not interested in, but don't object if someone else
wants to pick it up
1.21 A build infrastructure change that does not apply to us

Obtained from: atatat@NetBSD.org

Bring in the change from NetBSD 1.18:

"If using stat (the -L flag) and it fails, fall back to lstat(). It
may be the case that we're examining a broken symlink, and anything is
better than nothing."

The changes in 1.14 through 1.17 were not relevant to us.

Obtained from: atatat@NetBSD.org

stat: Allow -f %Sf to display the file flags symbolically.

I have changed the patch slightly to show '-' if there are no flags just
like ls -ldo does.

The NetBSD Foundation has granted permission to remove clause 3 and 4
from their software.

Let stat(1) use fdevname(3).

Because we now have a reliable library function that converts file
descriptors to character device names, let stat(1) use this. This means
it can now do the following:

$ stat -f %N
/dev/pts/0

I've changed main() to set file properly, so output() is never called
with file set to NULL.

Approved by: dougb (older version, still used devname)

Import NetBSD's 1.10 version, which includes the ability to display
the new inode birthtime field, a few other small cleanups, and
synchronization with our #include <sys/types.h>.

Adjust the size passed to readlink so that the null termination
falls within the range of the path variable.

I was too conservative with my header changes, so restore some sanity
via bde. atatat@NetBSD.org made basically the same change in their
version, so bring over their CVS Id which I neglected last time.

Obtained from: bde, Andrew Brown <atatat@NetBSD.org>

A cooperative effort...

1. Update the code to the latest from NetBSD, which includes:
* A new command line option to suppress stat(2) errors
* Output is now done via stdio
* Fixes for bitwise OR'ing of letters

2. Andrew from NetBSD merged in our own Johan's readlink patches.

3. Andrew also merged in some brucifications.

I made some small contributions to the header cleanup, and tried
to generally improve the overall style(9)'ishness. I also documented
the new -q option and added the *LINKS to the Makefile.

All responsibility for mistakes in merging the contributions
from the above is mine.
