This implements the xvp VNC extension, which is described in the
community version of the RFB protocol:
http://tigervnc.sourceforge.net/cgi-bin/rfbproto
It is also mentioned in the official RFB protocol.

When not calling rfbRegisterProtocolExtension() the extension mutex
is uninitialized but used upon calling rfbGetExtensionIterator() and
rfbReleaseExtensionIterator() in rfbNewTCPOrUDPClient(). This causes
libvncserver to crash on Win32 when building with thread support.

This is a small addendum to 0797e42a.
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.

Some (all?) autotool versions do not properly prefix
WORDS_BIGENDIAN with LIBVNCSERVER_, so do that manually
here.

Thanks to Lorenz Kolb for reporting.

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.

The header file and most of the functions referred to
do not exist in libvncserver.

MinGW32 (or more exactly, a rpcndr.h file included by
winsock2.h) typedefs a 'boolean' type that jmorecfg.h
included by jpeglib.h also tries to typedef.
So, tell the jpeg headers.

The hook is still called after InitialiseRFBConnection() so we can choose
the color settings depending on the vnc server (or settings) in that hook.

This way one can use the "VNC server default format" pixelformat if the
client supports it, or perform a workaround (Intel AMT KVM "classic vnc"
server only works using 8bit colors in RFB3.8)
