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).

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.

UNIXPW_DISABLE_SSL and UNIXPW_DISABLE_LOCALHOST work correctly.
Make -loopbg actually imply -bg.
entire desktop. map port + 5500 in reverse connect. Add id_cmd remote
control functions for id (and other) windows. Allow zero port in SSL
reverse connections. Adjust delays between multiple reverse connections;
X11VNC_REVERSE_SLEEP_MAX env var. Add some missing mutex locks; add
INPUT_LOCK and threads_drop_input. More safety in -threads mode for
new framebuffer change. Fix some stderr leaking in -inetd mode.
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.

As -listen mode isn't really working under UNIX and not at all under

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.

set the port to listen on and really ensure that the
window of the fork()ed instance is closed.
works somewhat: it's now actually possible to listen for an
incoming connection and to close it again, but the second
connection attempt fails with 'XIO: fatal IO error 11
(Resource temporarily unavailable)'. this could relate to the
fact that SDL uses threads internally and we're fork()ing
here...

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.
