Given an IPv4 address and prefix for a shared config, figure out the DHCP address range automatically. To keep things simple we allow a max of 252 addresses (not including network address, broadcast address, and the hotspot) no matter what prefix you use, so if the address is 10.0.10.1, you still only get a range of 10.0.10.2 -> 10.0.10.254. But we also leave some addresses available above the host address for static stuff, like we did before. This is done on a sliding scale from 0 to 8 addresses, where about 1/10th the number of available addresses are reserved. https://bugzilla.gnome.org/show_bug.cgi?id=675973
