net-firewall/shorewall*: v4.5.21.2 added

Changelog
=========
1)  Previously, the AutoBL action would fail if the kernel and iptables
    did not support the Recent Match '--reap' option. A new REAP_OPTION
    capability has been added to work around this issue.

2)  The Shorewall-core installer no longer reports an error from 'cp'
    stating that it could not stat the shorewallrc file.

3)  When a non-root user attempts to execute 'version -a', the CLI no
    longer attempts to get the version of the compiled
    firewall. Previously, the command issued the following diagnostic
    when run by non-root:

    	 /sbin/shorewall: /var/lib/shorewall/firewall: Permission denied

4)  Shorewall no longer uses 'fgrep' thus allowing for use on systems
    without that utility. All uses of 'fgrep' have been replaced by
    'grep -F'.

5)  Placing |<mark> in the ACTION column of the tcrules file no longer
    raises a fatal compilation error.

6)  Support has been added to the Shorewall-core configure scripts and
    installer for Ubuntu Raring.
