ipv6_pool structure
This structure is part of a range of addresses or prefixes. A range6 or prefix6 statement will map to one or more of these with each pool being a simple block of the form xxxx/yyy and all the pools adding up to comprise the entire range. When choosing an address or prefix the code will walk through the pools until it finds one that is available.
The naming for this structure is unfortunate as there is also a v4 pool structure and the two are not equivalent. The v4 pool matches the ipv6_pond structure. I considered changing the name of this structure but concluded that doing so would be worse than leaving it as is. Changing it adds some risk and makes for larger differences between the 4.1 & 4.2 code and the 4.3 code.
