The "happy eyeballs" RFC states that on receiving a negative response
for an IPv6 address lookup, we should wait for the IPv4 lookup to
complete and use any results we get from there.
The current code was not doing that: it was rather setting a timeout for
failing the resolution entirely. In scenarios where the IPv4 response
comes more than 50ms after the IPv6 response (which is easily attainable
under valgrind in certain configurations) this means that the IPv4
response will never come.
Remove the timeout and just wait.

The parent GNetworkAddress contains a shared list of resolved
addresses that is used as a cache for multiple enumerations.
This commit ensures that the cache is only set upon completion of
DNS lookups and only read once by enumerations to avoid being in a
bad state.
Fixes#1771
Some of these have a negative master/slave connotation, and they add no
value. Change or drop them.

While gtk-doc can currently detect a link to a symbol which has been
pluralised by adding ‘s’, it can’t detect when ‘es’ is added. While
that’s being fixed, reword the documentation so the links are generated
correctly anyway.

Previously once the end of addresses was reached it would return
NULL even if it was waiting on a dns response. Now it will keep
waiting so all addresses are received.
Fixes#1680
As RFC 8305 recommends we can start multiple DNS queries in parallel
to more quickly make an initial response, especially when one is
particularly slow/broken.
Add string serialisation functions for GNetworkAddress, GSocketAddress,
GUnixSocketAddress, GInetSocketAddress, GNetworkService and
GSocketConnectable. These are intended for use in debug output, not for
serialisation in network or disc protocols.
They are implemented as a new virtual method on GSocketConnectable:
g_socket_connectable_to_string().
GInetSocketAddress and GUnixSocketAddress now implement
GSocketConnectable directly to implement to_string(). Previously they
implemented it via their abstract parent class, GSocketAddress.

This is a convenience method for creating a GNetworkAddress which is
guaranteed to return IPv4 and IPv6 loopback addresses. The program
cannot guarantee that 'localhost' will resolve to both types of
address, so programs which wish to connect to a local service over
either IPv4 or IPv6 must currently manually create an IPv4 and another
IPv6 socket, and detect which of the two are working. This new API
allows the existing GSocketConnectable machinery to be used to
automate that.
Based on a patch from Philip Withnall.

Make sure that the @ sign is inside the authority part before attempting
to parse the userinfo. We do this by checking if the @ sign comes before
any of the possible authority delimiters.
Add unit test to verify parsing of ftp://ftp.gnome.org/start?foo=bar@baz

In addition to the standard "192.168.1.1" format, there are numerous
legacy IPv4 address formats (such as "192.168.257",
"0xc0.0xa8.0x01.0x01", "0300.0250.0001.0001", "3232235777", and
"0xc0a80101"). However, none of these forms are ever used any more
except in phishing attempts. GLib wasn't supposed to be accepting
these addresses (neither g_hostname_is_ip_address() nor
g_inet_address_new_from_string() recognizes them), but getaddrinfo()
accepts them, and so the parts of gio that use getaddrinfo()
accidentally did accept those formats.
Fix GNetworkAddress and GResolver to reject these address formats.

GNetworkAddress was allowing IPv6 scope ids in g_network_address_new()
/ g_network_address_parse(), but not in g_network_address_parse_uri().
Fix that.

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.
If the resolver reloads (ie, if /etc/resolv.conf changes),
GNetworkAddress needs to re-resolve its addresses the next time it's
enumerated. Otherwise hosts that have different IP addresses inside
and outside a VPN won't work correctly if you hold on to a
GNetworkAddress for them for a long time.
https://bugzilla.gnome.org/show_bug.cgi?id=694181
If a GNetworkAddress is created with a hostname like "fe80::xxx%em1",
make sure that the scope_id corresponding to "em1" is present in the
GSocketAddresses it returns when used as a GSocketConnectable.

The code that is checking the userinfo part was accidentally
given a pointer to the end of the userinfo, so it was not
checking the right portion of the string at all.
(which shouldn't ever have been part of the API. Grr.)
Solaris /etc/services doesn't even have "http", which was causing
tests/network-address to fail...
Previously, the code only initialized the enumerator if the address
hadn't had cached addresses. But creating an enumerator cached the
addresses, so the second one failed to work.
This patch implements method proxy_enumerate from GSocketConnectable for
all connectables (GNetworkAddress, GNetworkService, GInetSocketAddress
and GUnixSocketAddress).
