Allow conditional dependencies between rects when decoding
Some encodings only cause dependencies between rects some of the
time. Make sure we can allow parallel decoding of those rect that
aren't dependent on each other.

Make the decoder multi-threaded
This implements the basic infrastructure for multi-threaded
decoding of rects. However there is just one thread reading data
and one thread decoding it. More logic is needed to safely decode
multiple rects at the same time.

Clear up ZlibInStream::reset() behaviour
It previously only did a reset of the ZlibInStream object, not the
underlying zlib stream. It also had the side effect of flushing
the underlying stream and disassociating from it.
Clear things up by changing the naming, and introducing a proper
reset function (which is needed by the Tight decoder).

Split decoders into a read and decode step
We need to split these steps up in preparation for multi-core
support. Reading needs to be done in a serial manner, whilst
decoding can be done in parallel.
This also involved a rather large cleanup of the Tight decoder.

Delegate decoder object management to a separate class
Done in preparation for multi-core decoding. Keeps the complexity
out of the other classes. This also moves ownership of the
framebuffer in to CConnection. It's the CConnection object that is
aware of the threads and how to synchronise with them. Therefore
the ownership of the framebuffer must also be there to make sure
it isn't deleted whilst threads are working.

Ensure that libjpeg-turbo headers are included
On some systems, the build was picking up jpeglib.h from the system
include directories, and if the system's version of libjpeg[-turbo] used
a different API/ABI version than the one specified in JPEG_LIBRARY, this
led to a "Wrong JPEG library version" error at run time.

Return TcpListener pointers rather than objects
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.

Make sure fallback block handler remains enabled
Commit f8e3b34 introduced a regression where the fallback write block

Display partial updates on slow transfers
Normally we only display screen changes once we have the updates for
the entire screen. This may give the impression that the viewer is
hung though. So display the partial data if the update is taking to
long to arrive.

Fixes for X509 CA certificate handling
95f39a5 introduced a regression whereby an exception would be thrown
when a PEM encoded CA certificate file containing one or more blank
lines was read in under Apple Java 6. Additionally, CA certs were
being appended to the ~/.vnc/x509_savedcerts.pem file even if they
were already included in it. Also fixes a possible FileNotFoundException

Refuse to start Xvnc if we failed to initialise a screen
