Copy stable/9 to releng/9.3 as part of the 9.3-RELEASE cycle.

MFC r234775:

As cron(8) is started with '-s' by default, timezones that observe
DST should not need to worry about scheduling jobs when the DST time
changes.

Rather than removing the BUGS section in crontab(5) regarding this,
note that disabling '-s' may still cause jobs to be executed twice or
not at all.

Merge from head to stable/9:

r230655:

MFC r227981:
Point out that @reboot runs at every cron startup, not just system
startup.

$Id$ -> $FreeBSD$

Christen a BUGS section for an explanation of the impact of Daylight
Savings Time on cron(8). If we ever introduce some work-around code for
handling jobs scheduled for a time that "doesn't happen" due to DST,
the section should be renamed to IMPLEMENTATION NOTES.

Log run-time parsing errors now

Use getpwnam before getpwuid since two users with same uids can exists
(affects new login classes code only)

The same fixes as in inetd: by default run `system crontab things' with
daemon login class now, not restrict them to user class breaking
compatibility with old way (so-called nobody limits problem)

Implement user[:group][/login-class] syntax in system crontab
for more flexible control (the same as in inetd)

Sort cross refereces in section SEE ALSO.

Use err(3). Rewrote man page in mdoc format.

Revert $FreeBSD$ to $Id$

crontab(5) incorrectly documented the dom/month arguments.
They have valid ranges of 1-31 and 1-12, not 0-31 and 0-12.

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.

Paul Vixie's cron, version 3.0. Munged into bmake format. If this goes
well, expect our two seperate directories for cron and crontab to go away
shortly.
