Fix regresion that prevented -A0 from working as before.
This can be used to disable the default behavior of reporting events
for the weekend on a Friday.

Fix a bug with -flag where later events may be shown when they should not be.
The problem is caused by the special handling of Friday, where calendar will
show the upcoming events for the weeked as well. This change disables the
special handling of Friday for the -B option, as was already done for -A.
From Andy Bradford.

tweak the code a bit and add a -w option to display day of week.

tzfile.h is an internal header that should never have been installed.
What's worse, the tzfile.h that gets installed is over 20 years old
and doesn't match the real tzfile.h in libc/time. This makes the
tree safe for /usr/include/tzfile.h removal. The TM_YEAR_BASE
define has been moved to time.h temporarily until its usage is
replaced by 1900 in the tree. Actual removal of tzfile.h is pending
a ports build. Based on a diff from deraadt@

shuffle extern decl of header[] so gcc4 doesn't complain about
incomplete types.

Part one of userland __P removal. Done with a simple regexp with some minor hand editing to make comments line up correctly. Another pass is forthcoming that handles the cases that could not be done automatically.

- Prevent users from hanging or killing 'calendar -a', at the cost of
one additional fork() per user who has a calendar file. Side effect is
that root runs much less code.
- Use login caps so we don't, for example, give a user more processes than
he's allowed.
- tmpfile() rather than mkstemp() means never leaving junk behind.
- Don't let 'calendar -a' take more than a day.

Show periodic events the correct number of times.
Calculate special events (Easter) correctly regardless of which year
they occur in (thus fixing user/562).
Keep locales and special event names from propogating from one user
to the next during "calendar -a".
Set up a framework to handle special events other than Easter (for instance,
Jewish events, eventually).
Various other fixes.

Sort output by date; include framework for showing periodic events more than
once
