Problem description:

This patch contains fixes for numerous bugs in cron(8), at(1), and batch(1)
which cause scheduling problems, among which is one that allows jobs to run twice.

	1023418: cron queue handling and scheduling is broken
	1012011: Initialize USER as well as LOGNAME environment variable
	1017698: cron sends erroneous error message when job can't be executed
	1014181: add pid and queue name to the CMD syslog message
	1012398: "cron"/"at"/"batch" runs more jobs than queue limit
	1022379: cron executes crontab entries twice  (duplicate of 1027075)
	1011113: invalid sys_errlist message number is >= sys_nerr,
		 not > sys_nerr
