On some network conditions, WSARecvFrom() may return WSAECONNRESET
or WSAENETRESET error code to indicate that the connection has been
broken and should be reset. According to MSDN documentation,
WSAECONNRESET mean that the virtual circuit was reset by the remote
side executing a hard or abortive close. Also, it would indicate
that a previous send operation resulted in an ICMP "Port Unreachable"
message. For a datagram socket, WSAENETRESET indicates that the time
to live has expired.
Previously, hasPendingDatagram() discarded datagrams with these
errors and reported no data available. This behavior is incorrect
and can lead to infinite "freezing" of the socket.
This patch allows to handle these notifications as a result of the
readDatagram() call.

There was a small amount of time between the last readDatagram() call
and disabling a read notifier in case the socket had a pending
datagram. If a new datagram arrived in this period, this qualified as
absence of a datagram reader. Do not change the read notifier state
because it is disabled on canReadNotification() entry and always enabled
by the datagram reader.
Thanks to Peter Seiderer, who investigated the same: "Querying
hasPendingDatagrams() for enabling/disabling setReadNotificationEnabled()
is racy (a new datagram could arrive after readDatagam() is called and
before hasPendingDatagrams() is checked). But for unbuffered sockets the
ReadNotification is already disabled before the readReady signal is
emitted and should be re-enabled when calling read() or readDatagram()
from the user."
However, this patch does not completely solve the problem under Windows,
as the socket notifier may emit spurious notifications.

needed if we needed to get a bigger socket address and that only happens
with Unix sockets (paths).
sockaddr_in6, however, was just wrong. Some systems derived from BSD,
like OS X, have a sXX_len field containing the length of the socket
address structure and our qt_sockaddr_in6 was missing sin6_len. As a
result, setting sin6_family was just plain wrong on little-endian

parameter for readDatagram() and an "in" parameter for writeDatagram().
The header pointer in readDatagram() is allowed to be null if the
PacketHeaderOptions indicates WantNone. Otherwise, it must not be null.
The extra options parameter is introduced because we may not always want
all the metadata upon reception. For sending, we know what to include or
not based on what's set in the incoming header parameter.
QIpPacketHeader splits sender and destination because we'll be able to
return both on datagram reception.
