Do a proper cleanup when one of the termination timeouts trigger
rather than just exiting on the spot. This makes sure we don't leave
stray stuff around, e.g. unix socket files.

Windows tries to do a copy of it, and it is too complex to survive
that. Just reference the object directly as we know the source of
the message here.

It is functionality specific to WinVNC, so move the code there
to make things more clear.

Removed the last parts of VNCSConnectionST's back door in to
VNCServerST and let the parent class fully handle coordination of
clients, and access to the desktop.

Make things simpler by making this a part of the SDesktop interface
that always needs to be implemented.

Force queryConnection() to always call back to approveConnection()
rather than return special values. This makes the flow easier to
follow as it will be the same in all cases.

Applets don't work anymore so remove everything that has to do
with serving them.

We use polymorphic exception objects, so catching by value invokes
the copy constructor and stuff that we don't really want.

Makes the code more general and not directly tied to specifically
TCP sockets.

It was only used by WinVNC, so push it there instead.

Use the platform independent primitives instead.

We've changed the service name a couple of times for various
reasons. Make sure the old versions are removed when the new one
is registered.

We have lots of code that deals with Windows versions that we no
longer support anyway. Clean out all of this old cruft.

The identifier is used to compute the registry path, and should
ideally be kept short and without spaces.

The argument named "desc" was not actually the description, but
rather the short "display name". Add handling for the actual
description to reduce confusion.

It is easier to control object life time and avoid magical socket
duplication by having a single TcpListener object to pass around.
We have to be more careful about deleting the object though.

Avoids conflicts with the original RealVNC implementation, or any
other forks of that code.

It is needed by WinVNC, but got removed in 892d10a70. Also fix
a couple of issues:

 - Use getnameinfo() in order to be compatible with Windows XP
 - Make it static since it doesn't use a specific socket
 - Respect UseIPv4 and UseIPv6
 - Flags for getaddrinfo() that match binding code
 - Dummy service value for Windows compatibility

It's either not used, or no longer relevant.

Patch by Jochen Tucht, fixes bug 135.

before windows.h for correct winsock behaviour. mingw-w64 also enforces
this order, so to avoid compile errors we must include windows.h late in
all files.
