Gets rid of a loooot of code and complexity.
Colour map clients are still supported through an
automatically generated map, but we lose the ability to
develop a client or server that uses colour maps
internally.
We were not handling the "sync next" fence properly as we sent the response
right after we got the request (instead of waiting for the next command).
This created a race where we could lose pixel format sync between the client
and the server.

We need to explicitly trigger a framebuffer update for server side rendered
cursors. Previously this happened to work anyway because we had a lot of
triggers for updates. After the cleanup, we need to be more explicit.

Make the comparing update tracker a bit more flexible. It can now be in an
"auto" state where it will be enabled until we deem that the client is better
of without it (currently triggered by explicitly stating a low compression
level).

Cork the outgoing TCP stream while we still have messages to process. This
allows more efficent use of the congestion window as we will send fewer packets.

Clean up the interface for VNCSConnectionST. Entry points are more apparent
and the data flow is now more strictly aimed towards this connection class.

Don't try to push out another update if the socket is already full. This
avoids stalling the entire server because of one slow client.

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.
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.

Reverted the second part of 3971. I suspect that this code is actually
broken, so let's keep the warning until we know it's correct.

* The return statement in needRenderedCursor was way too complicated,
separated into intermediate variable.
* Using parenthesis in setStatus bit masks.

Make sure we send any modifications to the desktop layout in a message that
does not modify the framebuffer data. This is required to make sure we have
a valid state on the client as it drops the framebuffer when it recieves a
framebuffer dimension change.

UltraVNC sends a new non-incr. FUR when it gets a DesktopSize rect, and
TightVNC drops the framebuffer, so we can't realistically send it every
non-incr FUR. Besides, the client needs to keep track of framebuffer
dimensions anyway.

It has some warts, but should be feature complete. Most of the magic happens
in the desktop class though.

Remove the "video" feature and its associated custom JPEG handling.
Having the client specifiy the video region is conceptually wrong
and a problem like this should be handled by better encoding selection.

Implemented support for DesktopName pseudo encoding, which allows
updating the desktop name on the fly.
Tested in ThinLinc since 2008-01-07.

[Development] Disabling special video encoding when the VideoPriority parameter is 0. In this case, video updates will be encoded similarly to normal updates.
[Enhancements, refactoring] Rationalized functions to control video
rectangle selection and default video rectangle. Added more logging and
improved error checking in the related code.

Restored the functionality of the VideoPriority parameter. This time, it
should work correctly even over slow networks, when update requests go less
frequently than polling cycles. This version does not give any special
meaning to the value 0, it is equivalent to 1.

Removed support for continuous updates, a TightVNC-specific RFB protocol
extension. That extension used to send framebuffer updates continuously, not
waiting for clients' requests. However, it showed bad results with
low-bandwidth connections, due to lack of proper data flow control.

Code cleanups. The most important change is that we now always use UpdateTracker's getUpdateInfo() and never call get_changed(), get_copied() and get_delta() member functions.
