Add SSL support to UltraVNC Java Viewer (has filetransfer gui).  Fix UltraVNC bugs and improve FTP gui a bit.

ssvnc: SOCKS support, PORT=, Verify all Certs and accepted certs logging. x11vnc SSL debugging output.

x11vnc: lower -wait and -defer to 20ms. Drop client doing ultravnc stuff in -unixpw during login phase.

This buglet made it impossible to double include rfb.h from C++.

Maybe at a later stage, we want x11vnc to pick up on existing
libvncserver.so and libvncclient.so, but right now, x11vnc and the
libraries progress together (and thus it is better to build static,
necessarily up-to-date libraries for x11vnc).

Thanks to Guillaume Rousse, we now use libtool to build shared libraries.

There seems to be a locking problem in libvncserver, with respect to how
condition variables are used.

On certain machines in our lab, when using a vncviewer to view a display
that has a very high rate of updates, we will occasionally see the VNC
server process crash.  In one stack trace that was obtained, an assertion
had tripped in glibc's pthread_cond_wait, which was called from
clientOutput.

Inspection of clientOutput suggests that WAIT is being called incorrectly.
The mutex that protects a condition variable should always be locked when
calling wait, and on return from the wait will still be locked.  The
attached patch fixes the locking around this condition variable, and one
other that I found by grepping the source for similar occurrences.
