Add the ip_pool_select_addr4 function to select a random subnet of requested size from an address space defined by a string list (for use with the AP profile [IPv4].Address and the global [IPv4].APAddressPool settings), avoiding those subnets that conflict with subnets in use. We take care to give a similar weight to all subnets contained in the specified ranges regardless of how many ranges contain each, basically so that overlapping ranges don't affect the probabilities (debatable.)
