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.
This uses a separate-socket approach since there are systems that do not
support dual binding sockets under *any* circumstances, for instance
OpenBSD. Using separate sockets for IPv4 and IPv6 is thus more portable
than having a v6 socket handle v4 connections as well.

Move the hixie disconnect hack to websockets.c. Removed
the remaining websockets vars from rfbClientPtr, so all
websockets stuff is hidden behind an opaque pointer.
Added wspath member to rfbClientRec which holds the
path component of the initial websocket request.

[jes: moved out GnuTLS and OpenSSL support, added a dummy support, to
separate changes better, and to keep things compiling]

Has a bug: WebSocket client disconnects are not detected.
rfbSendFramebufferUpdate is doing a MSG_PEEK recv to determine if
enough data is available which prevents a disconnect from being
detected.
Otherwise it's working pretty well.
[jes: moved added struct members to the end for binary compatibility with
previous LibVNCServer versions, removed an unused variable]

This is required to be able to do proper event loop integration with Qt.
Idea was taken from vino's libvncserver fork.

In commit 079394ca5b new code with
insufficient checks was introduced causing a segfault when doing a
HTTP server connection. Such connections have no screen set in the
client data structure.

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.
