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.

Redefining strncasecmp to _strnicmp makes libvncclient hang forever in
SetFormatAndEncodings() on Windows when built with MinGW64.
Reported by Tobias Doerffel <tobias.doerffel@gmail.com>, thanks!
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.
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.

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.
Closes: 3007302
[jes: pulled the "host" declarations into the conditionally compiled
blocks where that variable is used. Also fixed non-IPv6 connections.]

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)

client role in reverse connections. Improvements to logging in
ultravnc_repeater, ULTRAVNC_REPEATER_NO_RFB option. Increase
SSL timeout and print message if 'repeater' mode is detected for
reverse SSL connection. Fix RECORD scroll XCopyArea detection
with recent gtk/gdk library; set X11VNC_SCROLL_MUST_EQUAL

For some reason, this developer's automake no longer understands _SOURCES
lines anymore. Work around that.

The serverPort member is already set in rfbGetClient(), if we
set it again in rfbInitClient(), this breaks playing of vncrec
files (this relies on serverPort set to -1).
