Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Build lib/ with WARNS=6 by default.

Similar to libexec/, do the same with lib/. Make WARNS=6 the norm and
lower it when needed.

I'm setting WARNS?=0 for secure/. It seems secure/ includes the
Makefile.inc provided by lib/. I'm not going to touch that directory.
Most of the code there is contributed anyway.

Mechanically kill hard sentence breaks.

mdoc(7): Use the new feature of the .In macro.

mdoc(7) police: Use the new .In macro for #include statements.

Add __FBSDID's to libcalendar

Remove whitespace at EOL.

Set WARNS=2 on libraries that compile cleanly with it.

mdoc(7) police: normalize .Nd.

MAN[1-9] -> MAN.

mdoc(7) police: fixed broken references.

Introduce .Lb macro to libcalendar manpage.

Remove single-space hard sentence breaks. These degrade the quality
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

Replace beforeinstall target with new variables used by .mk system.

$Id$ -> $FreeBSD$

.Sh AUTHOR -> .Sh AUTHORS. Use .An/.Aq

Delete "typedef ... date" (see style(9)).
In the man page Use ".Pp" instead of blank lines, adopt English
and stress that the Julian->Gregorian switch took place at
different dates in different countries.
Suggested by: Garrett.

Added easterog() and easteroj() which compute orthodox easter for
Gregorian and Julian Calendar.
