When we allocate and use DPDK memory, we need to be able to differentiate between DPDK hugepage segments and segments that were made part of DPDK but are externally allocated. Add such a property to memseg lists. This breaks the ABI, so document the change in release notes. This also breaks a few internal assumptions about memory contiguousness, so adjust malloc code in a few places. All current calls for memseg walk functions were adjusted to ignore external segments where it made sense. Mempools is a special case, because we may be asked to allocate a mempool on a specific socket, and we need to ignore all page sizes on other heaps or other sockets. Previously, this assumption of knowing all page sizes was not a problem, but it will be now, so we have to match socket ID with page size when calculating minimum page size for a mempool.
