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'.

Make sure that each va_start has one and only one matching va_end,
especially in error cases.

Merge revisions 1.10 and 1.11 from DragonFly:

- Use real getopt() handling instead of the hand-rolled and
IOCCC-worthy "Micro getopt()" macros, plus clean up to the
option handling code:
* Sort the options in the switch statement;
* Plug piddling memory leaks when processing repeated options
by freeing strings before allocating them for a second time;
* Die with a fatal error if the requested report file cannot
be opened for appending;
* Don't call init() before usage() (to prevent the usage
message being mangled by changes to the terminal settings;)
- Clean up the usage message, both in usage() and in the main
program comment, both stylistically (sort and combine options)
and for accuracy (following the manual page, make note of the -s
and -S flags, and use the term 'send' instead of 'say' to reduce
confusion (SAY is the name of a command for output to the user,
not the connection.))

Rename logf --> chat_logf to avoid naming conflicts
with GCC built-in (and with C90 reserved library name).

Big cleanup. Remove unused stuff, make closer to style(9).

OK'ed by: peter (long time ago)

Replace various spelling with FALLTHROUGH which is lint()able

Remove local prototypes for main().

remove __P

Use STD{ERR,IN,OUT}_FILENO instead of their numeric values. The
definitions are more readable, and it's possible that they're
more portable to pathalogical platforms.

Fix a buffer overflow due to sending strings >1k in length. This is unlikely
to be a security problem, but it's not totally impossible. OpenBSD take note

make it so that chat doesn't fail when it can't get terminal params..
this allows it to work on non-tty input... also don't warn when this
happens as it could get noisy...

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
