8966f5046e Remove the 'DO NOT EDIT THIS FILE' crud that we spit out with 'crontab -l'.
Otherwise, "crontab -l > file; vi file; crontab file" adds an extra set
of "DO NOT EDIT" markers each and every time which is a bit silly.

c7517d5af9 Stop cron from shouting in the syslog. Use setproctitle() instead, since
smashing argv[0] doesn't have the intended effect of changing the ps(1)

be821963c1 Made the special handling of the daylight time switches optional,
enabled by the option "-s" (for dSt). This returned the default behavior
to its original form.

The new option name is not "-d" because that would cause associations with
"debug" and cron already has "-x" for debugging, so this would cause
confusion.

25e9ca2b19 Attempt to fix problem with users being able to convince the crontab
program to read any file which is a valid crontab file.

The fix is based on that used in NetBSD and OpenBSD - we keep the
file open while the user is editing it. This means that files must
be edited in place. Cron attempts to warn you if your editor does
not do this. The fact that the file must be edited in place is also
noted in the man page.

This patch has been confirmed to work by atleast one person on
-security and has been tested locally.

8261236de4 Fix a situation where a pointer which should point to dynamically
allocated memory was instead pointed to a static string.  A later
free() on the value of the pointer was a possible source of reported
"warning: pointer to wrong page" messages from cron.

Use consistent types in sizeof when malloc'ing memory for the
environment.

5ef4895832 This is a hack. Cron runs with stdin/out/err pointing to /dev/console,
which init thoughtfully revoke()'s when starting a getty on ttyv0.  This
Cron's popen() was passing these fd's through to cron children (ie:
sendmail, *not* normal cron jobs).  The side effects were usually
not noticed, but it tripped up postfix which did a sanity check to see
that stdin/out/err were open, and got EBADF even thought the fd's were
in use.  I seem to recall sendmail itself has hacks to work around
this problem, it had a checkfd012() function, possibly for this same
problem.  (Postfix has a workaround too now though..)

This is a hack, not a fix.  It's probably best to check and perhaps
close/reopen() /dev/console if needed each time around the event loop.
It would probably be useful to actually see any error messages from cron.

Prevent cron from going crazy if the time steps.  For example, if you
    have a system with hundreds of users and lots of different crontabs
    and your time steps back an hour, the old cron would then attempt to
    run an hours worth of cron jobs in a few seconds.
