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.
Move image encoding logic into a central EncodeManager class
This allows us to apply a lot more server logic
independently of which encoder is in use.
Most of this class are things moved over from the
Tight encoder.
If the client and server are using identical pixel formats, then perform Tight decoding directly into the viewer's back buffer, rather than going through the slow fillRect/imageRect routines.
CMake doesn't handle convenience libraries as nicely as autotools does. We
need to be explicit with -fPIC here as we use these in libvnc.so.

Ported encoding optimizations from TurboVNC. The changes to the Tight parameters were determined through extensive low-level profiling (see http://www.virtualgl.org/pmwiki/uploads/About/turbototiger.pdf). The other enhancements involved: (1) porting the solid subrectangle pre-computation code from TightVNC/TurboVNC (it makes a pretty big difference-- see report), (2) encapsulating the JPEG encoder in its own class (this eliminates a buffer copy, and the JPEG buffer is now set to a decent size where it shouldn't ever need to be paged or re-allocated, except in rare corner cases), (3) adding support for last rect. encoding (necessary to support the solid rectangle pre-computation enhancements.
Building the Xvnc server requires libtool control files of rdr, rfb,
network and Xregion, which a cmake build will NOT produce, this macro
tries to create a libtool control file *.la for the specified target
with libdependencies for a static library target.
Due to the automake part of Xvnc references to libtool files in source
tree you need to build vncviewer using cmake in the source tree.

Split out the pixel format conversion magic to its own class and make
TransImageGetter be just an ImageGetter interface to that functionality. This
allows more flexible use of the pixel conversion routines.
