In most cases, usage does not return, so mark them as __dead2. For the
cases where they do return, they have not been marked __dead2.

It's always been dead, ever since first import in 1994. It's still dead in
OpenBSD's version, too.

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'.
- 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.))

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.
