isc-dhcp updates and call for testing

[Josh Paetzel]

I have patches that update the isc-dhcp30 and isc-dhcp-31 ports.

isc-dhcp30 incorporates patches from Ubuntu to address a security  
advisory released against it.  Since it is no longer maintained  
upstream nothing official will be released.

If you wish to follow a maintained version, I have patches that update  
isc-dhcp31 to the latest version that addresses the security issues  
that were recently discovered.  These patches could use testing beyond  
what I can mock up locally.  If you try them out I could use feedback,  
whether good or bad.

The patches to isc-dhcp30 will probably be committed tomorrow.  I'd  
like to wait a bit to get feedback on the isc-dhcp31 patches, also the  
rcNG script will probably be updated a bit from what is in the patches  
to provide stylistic, but not functional improvements.

I am planning on getting a 4.0.x and 4.1.x port going soon as well,  
hopefully by this weekend.

Thanks,
