MFC 238024:
Add a one second sleep before touching the spool directory. If the touch
occurs in the same second as the earlier operations to create the temporary
file and the cron(8) daemon is rescans the spool directory during that
second, then the daemon may miss a cron edit and not properly update its
internal database.

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.

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.
