Besided making libvncserver reverseVNC IPv6-aware, this introduces some changes
on the client side as well to make clients listen on IPv6 sockets, too. Like
the server side, this also uses a separate-socket approach.
For security reasons, it can be important to limit which IP addresses a
LibVNCClient-based client should listen for reverse connections. This
commit adds that option.
To preserve binary backwards-compatibility, the field was added to the end
of the rfbclient struct, and the function ListenAtTcpPort retains its
signature (but calls the new ListenAtTcpPortAndAddress).
[jes: shortened the commit subject, added a longer explanation in the
commit body and adjusted style]

This is a small addendum to 0797e42a4a.
Seems that having IPv6 support in the OS does not necessarily mean that
IPV6_TCLASS is available. One such case seems to be Mac OS X 10.5.
This enables setting the DSCP/Traffic Class field of IP/IPv6 packets
sent by a client. For example starting a client with -qosdscp 184
marks all outgoing traffic for expedited forwarding.
Implementation for Win32 is still a TODO, though. See
http://betelco.blogspot.com/2009/03/dscp-marking-under-windows-at.html
for an overview of the Win32 QoS API mess...
Expands the SetNonBlocking() function in libvncclient/sockets.c to also
work under Windows and also changes it to honour maybe already present
socket flags.
A similar function was introduced for libvncserver as well and
all the #ifdef'ed fnctl calls replaced with calls to that one.

[jes: pulled the "host" declarations into the conditionally compiled
blocks where that variable is used. Also fixed non-IPv6 connections.]

Actually, initSockets() has to be called everywhere we possibly
use sockets the first time.
Also fix return value of initSockets().

On Windows, the WSA system needs to be initialized to be able to look up
host names.
This patch also changes *addr = 0 to use the constant INADDR_LOOPBACK
instead, which seems to be required on Windows.
SOCKET is redefined in winsock2.h so #undef it where winsock2.h
is included. The changes in rfbproto.c circumvent crosscompiler
errors like 'S_IFMT' undeclared ...', the Makefile.am changes
avoid building linux specific stuff for a win32 host target.
Also added configure option to specify sdl-config.
