x11vnc: Printout option -sslScripts.  Suggest -auth guess in error message.  Set fake_screen width and height.  Test for +kb in Xvfb.

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.

Reduce wait time for https. Add 'Login succeeded' output to unixpw panel.

        DIRECT: with an extra XFlush and other safety measures.
        fflush(stderr) much in su_verify.  Make the -unixpw env. vars
        UNIXPW_DISABLE_SSL and UNIXPW_DISABLE_LOCALHOST work correctly.
        Make -loopbg actually imply -bg.

ultravnc_repeater.pl scripts, find_display try FD_XDM on failure,
-quiet and -storepasswd changes, better port 113 testing.

-findauth/-auth guess FD_XDM=1 for root, work around xhost SI:localuser:root.

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.

rfbSetClientColourMap().  Up listen limit from 5 to 32.

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.
