perry 4cfab35c9c New feature: "?" for time specifications, means a single time selected at 
random from within the range at file read time. Very useful if you
want to avoid having a fleet of machines melt a server by all trying to
contact it at a precise time every morning. See docs for details.

Reviewed by: christos, apb, vixie, others.

XXX apb suggests, quite reasonably, that ?10-16/2 should mean
something like 10,12,14,16 or 11,13,15. I'm too lazy to do it right
now, but it should be done.

XXX vixie suggests, quite reasonably, that if you're using "?" one
should delay randomly by 0-59 seconds. In the modern NTP world, you
could imagine that with a million well synchronized machines the
second just at the minute would be hit quite hard. I'm too lazy to do
it right now, but it should be done.

XXX cron needs to be updated to Vixie's cron 4.1 code.

heas be21025dae Set SIGCHLD to SIG_DFL in cron's child; instead of SIG_IGN, which alters the 
behavior of wait() causing cron_pclose() to return bogus status and the logging
of bogus status in debug mode.

christos 102bb7e88c - eliminate a goto. 
- cast more returns to void.

  wait for other children.
- return exitstatus only if exited, and return the termination signal otherwise.

christos cf31b04130 PR/10957: Ed Ravin: Cron does not execute the last line in crontab if 
the trailing newline is missing. Fix by changing crontab(1) to not
allow installation of crontab files with missing trailing newlines.

christos 36e8d2b792 PR/28744: Ed Ravin: crontab with fewer than 3 comment lines dumps core 
in crontab -l.
The problem is that the skip_header code has a side effect of trying to
write to the new temporary cron tab if we run out of comments. Since we
don't have an output file in -l, we core-dump trying to fputc to NULL.
Simplify the logic so that we don't write in the skip_header function,
and we always return the first character after the comment lines to the
caller, skipping the '\n'.

atatat 4e34961a55 Jobs specified for @reboot are only popped into the job queue at cron 
startup time ("reboot" of cron, not the system), so okay_to_go() must
always say they are good to go.  Otherwise they never will.  All other
meta-timetags pertain to regular times, so they are (or were)
unaffected.
