The current definitions were mostly useful to glibc and followed its
feature_test_macros(3) documentation.

However, this means other platforms still had problems when building with
strict compilation flags. _BSD_SOURCE, for example, is only recognized by
glibc, and other platforms sometimes need _XOPEN_SOURCE instead, or even the
removal of some definitions (such as the outdate _POSIX_SOURCE one).

_POSIX_SOURCE also had to be conditionally defined in some places, as what
it enables or disables during compilation varies across systems.

The various other headers include windows.h and the winsock headers
which give an error when SOCKET and socklen_t are already defined.

LibVNCClient: Remove all those WITH_CLIENT_TLS #ifdefs and move GnuTLS specific functionality into tls_gnutls.c.

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]

The auth methods that employ Getcredential() will only be used if the client's
GetCredential callback is actually set.

The functions gnutls_*_set_priority we used were marked deprecated since
latest GnuTLS version 2.12. However the replacement function
gnutls_priority_set_direct is available since 2.2, which is even lower
than our version requirement 2.4 in configure. The patch just replace
the deprecate function to fix the compile warning.

My bad. There we see what the encodings test is good for ;-)

There can not be more than 255 security types and MSLogon is
RFB 3.6 only.

GnuTLS seems to expect proper errno values internally. So set them in our
custom push/pull functions. Parts of the patch stolen from libcurl, thanks!

Winsock does NOT update errno for us, we have fetch the last error
manually using WSAGetLastError().

According to the minilzo README, this brings a significant
speedup on 64-bit architechtures.

No functional changes. All files used by _both_ libvncserver and
libvncclient are put into a 'common' directory and references
from other files as well as Autotools and CMake build systems are
updated.

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.

Redefining strncasecmp to _strnicmp makes libvncclient hang forever in
SetFormatAndEncodings() on Windows when built with MinGW64.

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.

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.

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).
