Add support for TurboVNC pseudo-encodings and Grayscale JPEG compression so that, when a TurboVNC viewer is connected, the TigerVNC Server will behave exactly like the TurboVNC Server.
Further optimizations to the Tight encoder to eliminate getImage() overhead. The encoder now directly accesses the framebuffer for solid rectangle computation, JPEG encoding, and color counting (if pixel translation is not required.) Also moved everything in tightEncode.h into the TightEncoder class to eliminate all of the static mess (this will be important later on if we decide to multi-thread the encoder.)
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.
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.

After discussion with Constantin reverted 2433, 2434, 2436, 2437 and 2438
(build automation and i18n changes). Latest server changes (2439 and 2440)
are OK.
