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.

[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)

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).

It seems that vino does not send AuthOK when there is no password with
anonymous TLS, and it seems that vino is the only <3.8 VNC server that
handles anonymous TLS at all, so let's not wait for the packet that will
never come.

The return value now better reflects what has happened:
1 on success (incoming connection on listen socket, we
accepted it successfully), -1 on error, 0 on timeout.
Also change the select calls to not check _all_ possible
file descriptors.

To make this work, we also have to initialize sockets
to a default value of -1.
Also close a client listen socket if it's open.

Forking the whole process from deep within a library call does
not really work at all with apps that use multiple threads, i.e. every
reasonably modern GUI app. So, provide a non-forking listen function so
that the caller can decide if to fork, start a thread, etc.
This implementation adds a timeout parameter to be able to call the
listen function multiple times so that it's possible to do sth. else
in between, e.g. abort listening.

When working on a program which searches the display for some image, one
does not want to search again without getting an FB update. Add a
callback to make this possible.
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.

There was an unnecessary assignment, and an assignment of a string that
was to be free()ed later, so it has to be strdup()ed.

The flag handling (both compiler options and include paths) are a mess at
the moment. There is no point in forcing "-O2 -g" when these are already
the defaults, and if someone changes the defaults, chances are good they
don't want you clobbering their choices.
The -Wall flag should be handled in configure and thrown into CFLAGS once
rather than every Makefile.am. Plus, this way we can control which
compilers the flag actually gets used with.
Finally, the INCLUDES variable is for -I paths, not AM_CFLAGS. Nor should
it contain -I. as this is already in the default includes setup.

Highlite:
* use qualityLevel/zlib_buffer. No new variable is needed.
* Change coding style to recursive fashion.
* Change meaning of qualityLevel== 9 for easy calc zywrle_level:
old:zywrle_level== 1
new:disable ZYWRLE(same as ZRLE)
so, we should not use this value for compatible reason.
* Color mode handling isn't complete.
I provided and checked 16 bit colors(RGB555,RGB565) and
some color mode of 32 bit colors for little endian mode.
we must make and check 24 bit colors and big endian mode.

We need to process the rectangle (especially if it a type that contains
subrectangles or any kind of compression). UltraVNC should be fixed to
prevent these useless rectangles from being sent.
