Currently, the Windows code use Winsock2-specific APIs to try to emulate
calls such as inet_pton(), inet_ntop() and if_nametoindex(), which may not
do the job all the time. On Vista and later, Winsock2 does provide a
proper implementation for these functions, so we can use them if they exist
on the system, by querying for them during g_networking_init(). Otherwise,
we continue to use the original code path for these, in the case of XP and
Server 2003.
This enables many of the network-address tests to pass on Windows as a
result, when the native Winsock2 implementations can be used.

As it turns out, we have examples of internal functions called
type_name_get_private() in the wild (especially among older libraries),
so we need to use a name for the per-instance private data getter
function that hopefully won't conflict with anything.
When parsing an address, we need to re-set "len" between IPv4 and
IPv6, since WSAStringToAddress() might set it to sizeof(struct sin_addr)
when trying to parse the string as IPv4, even if it fails. Also, we
need to make sure to not pass strings to WSAStringToAddress() that it
will accept but that we don't want it to.
When stringifying an address, we need to clear the sockaddr before
filling it in, so we don't accidentally end up with an unwanted
scope_id or the like.

Install a public "gnetworking.h" header that can be used to include
the relevant OS-dependent networking headers. This does not really
abstract away unix-vs-windows however; error codes, in particular,
are incompatible.
gnetworkingprivate.h now contains just a few internal URI-related
functions
Also add a g_networking_init() function to gnetworking.h, which can be
used to explicitly initialize OS-level networking, rather than having
that happen as a side-effect of registering GInetAddress.

It turns out that just calling g_inet_address_get_type() isn't
enough, since its marked G_GNUC_CONST, so the call is optimized
away. If we assign the return value to a volatile location we ensure
it is called.
OS X's headers split up the current and old (BIND 4) nameserver stuff
slightly differently than Linux does, but explicitly including
arpa/nameser_compat.h does the right thing on both. Part of #580301
In glibc, IN6_IS_ADDR_UNSPECIFIED() et al. cast their argument to a
uint32_t*, so it doesn't matter whether you pass them the in6_addr
itself (which is what you're supposed to do) or one of its union
members (which is what we were actually doing). Solaris's macro
accesses the in6_addr fields directly though, and so only works if you
pass the actual in6_addr. #580194.
GResolver provides asynchronous (and synchronous-but-cancellable) APIs
for resolving hostnames, reverse-resolving IP addresses back to
hostnames, and resolving SRV records. Part of #548466.
Types and methods for dealing with IPv4 and IPv6 addresses (and UNIX
domain socket addresses under UNIX). This does not include code for
actual socket I/O.
Originally from "gnio". Much of the code was written by Christian
Kellner, Samuel Cormier-Iijima, and Ryan Lortie.
Part of #548466.
