Andrew Zaborowski e56e4ade90 ip-pool: Add subnet address selection logic
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.)
