This is a workaround to the continuous taint mode incompatibilities with this code.

- This patch introduces a new rc variable called "mailscanner_user". If you changed the "Run As User"
  variable in MailScanner.conf (which triggers taint mode) you MUST now also set the same value in /etc/rc.conf.
- Removed ulimit bump from startup script, since its now dynamically set at boot time based on system resources.
- fixes permission problems with pid file.

+	A new rc variable called mailscanner_user has been added to the
+	startup script. This is a temporary workaround to address the
+	numerous taint mode problems that are still present in the code.
+
+	If you changed the "Run As User" variable in MailScanner.conf

+	i.e. mailscanner_user="postfix"
+
+	The new variable uses su to start the master perl script as the
+	specified user, this effectively disables perl's taint mode.
