MFC r300005

swprintf() and apparently wcsftime() want the their output buffer size
specified in terms of the the number of wide characters and not
sizeof(buffer).

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.

- 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.

ncal(1) highlights the current date (or a date provided via parameter)
even if stdout is not a tty. If stdout is not a tty the data is
normally processed by other tools and no control sequences are
expected.

Use basename(3) to determine the name of the program.

Submitted by: Alexander Best <arundel@>

Replace -b with -C and -B (as proposed by Alexander).
Add -3, -A and -B to the usage.
Update regression test for the new parameters.

- With the introduction of -A, -B and -3, not all combinations of
arguments makes sense anymore. For example, what would a combination
of -3 (show three months) and -y (show the whole year) do?
We will abort on these cases.
- Move the debug option -d to -H (from highlight), while -d is now
used for setting the day of "today" so that -y and friends can
be tested.

- Fix the highlighting for non-terminals when the last week is not
7 days long.
- "-m <N> <YYYY>" now prints only the month, not the whole year.

- document the -3, -A and -B properly in Synopsis.
- add highlight of current date for non-terminals.
- fix -J option.
- code cleanup.

Since the width is always 2, it is enough to put just one

Mention -h in usage() and manpage. Rename term_{r,e} to term_{so,se}.

Suggested by: ru
Approved by: ed (mentor)

Fixed multi-byte character support to actually work.

Couple of changes based on feedback

o Change mr/me to so/se [1].
o Introduce a -h option to disable highlighting. [2]
o Spell STDOUT_FILENO as such and pass NULL to tgetent()
to handle the case of unset TERM. [3]

Implement highlighting of today in month view of cal/ncal just like
gnu cal does. This is currently disabled for year view because of hard
coded padding in that case. This will hopefully be fixed soon.

Multibyte character support for cal(1).

Implement a new feature for the "-m" option: if the month number is
followed by 'f' or 'p', use the following or preceding month of that
number, respectively. Document this. Also includes other minor
grammatical and punctuation fixes to the manual page (capitalize
Easter, etc.).

Add a `-m month' flag to provide a more convenient interface for
displaying a calendar for a specific month of the current year than
`cal $(date +"%Y") month'. A few minor code cleanups. Set WARNS=1.
(This code is WARNS=5 clean except for "`O' modifier used with `%B'
strftime format", which is legal in FreeBSD but GCC doesn't know about.)

Sync usage and synopsis. Add rcsid.

1. Don't be confused if the first day of a month is dropped due to
Gregorian Reformation. E. G. in Albania December 1, 1912 doesn't exist.
2. Add some countries in the switch table (BE, FI, LN, LU)

That is Claus Tondering's Calendar FAQ.
