[PATCH v3 1/2] Add new function die_with_status

From: Fredrik Gustafsson <iveqy@iveqy.com>

Message-ID: <1307605623-2831-2-git-send-email-iveqy@iveqy.com>
In-Reply-To: <1307605623-2831-1-git-send-email-iveqy@iveqy.com>

This function takes the exit code as a parameter.

This allows scripts to control the exit code when they need to die.

Make the old die-function to use die_with_status for simpler maintenance.

die no longer prints empty die messages, this is a changed behavior.
