Comparing to NetworkList, I prefer std::vector<SimpleStructOfNameAndAddress>.
And put the struct as well as things like CreateFromAddrInfo in the
ppb_host_resolver_shared files.

Thanks! I replaced the hand-written NetworkList to
std::vector<NameAndAddressPair>.

It doesn't need to be virtual.

NetworkList is removed.
