christos d0e5eb6a35 from Anon Ymous:
Remove a "(void)&" construction: iop is used by the parent
and always set after the vfork().  Also flag some parameters __unused
so this will compile with -Wextra.

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.
- use waitpid instead of wait() to wait for our process, not accidentally
  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

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.

christos c2b5bf99ef PR/15142: Kevin P. Neal: cron does not pay attention to login_cap(3)
I simplified the patch addressed certain security concerns. I only
allowed setusercontext() to set resource limits/priority and umask,
because these are the values that are relevant from login.conf. The
rest of the settings (uid/gid/initgroups) should be done using e->uid
and e->gid like they were before, not from:

	struct passwd *pwd = getpwnam(getenv("LOGNAME"));

Finally login_cap's (path/env) are irrelevant in this context since
we want to use our e->envp anyway to execute the command.

atatat 29bf0c2821 Implement CRON_TZ and CRON_WITHIN to provide finer control over job
execution.  CRON_TZ sets the time zone within which a job is
considered for execution (but not in which it runs), and CRON_WITHIN
allows jobs to be skipped whose execution is delayed for any reason
(eg, the system was sleeping or the load average is too high for
timely execution).
