Disable Composite extension by default in the legacy-friendly TigerVNC build. Justification: Some older versions of Gnome do not work properly when Composite is enabled. This is known to be a problem with RHEL 4 (Gnome 2.8), and it causes the legacy-friendly build to be unusable on that platform. Newer Gnome versions, such as 2.16.0 (the version in RHEL 5), work properly with Composite enabled, but those versions don't support compositing anyhow, so it doesn't matter if we remove the extension. Typically, platforms that are new enough to support compositing are also new enough to not require the legacy-friendly build of TigerVNC. Further, Composite can be re-enabled by simply adding --enable-composite to the XORGCFGFLAGS env. variable prior to executing 'build-xorg build'.

Put the TigerVNC marker at the end instead of the beginning of the window
title, making it easier to differentiate windows. At the same time remove
the translation tags as there is nothing in there that should be translated.

Avoid translation strings with leading and/or trailing whitespace. Our
experience is that translators very often fails to notice them and
forgets to include the whitespace in the translated string.

We can't assume that Pixman is under ${includedir}, because ${includedir} depends on the install prefix. Fortunately, XSERVERLIBS_CFLAGS should contain the correct include directory for Pixman, so we can use this variable directly or parse it for the include directory.

Clarify when in-tree version of Zlib is being used, and remove redundant "not found" message for the system version (find_package() already takes care of that.)

Make sure to include config.h in every compilation unit. Otherwise,
the necessary defines will only be visible as a side effect of
including other headers, leading to problems with things like
translations, which will fail in various places.

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.

Revert r4498 and fix #3305357 properly. The issue was two-fold: (1) the compress buffer allocated by the Tight encoder was not large enough, and (2) Zlib 1.2.5 can sometimes call deflate(..., Z_BLOCK) within the body of deflateParams(), so we need to check avail_in after calling checkCompressionLevel() to ensure that there is still data left to compress before we call deflate() again.

(Re-)fix static Xvnc build. We can leverage the BUILD_STATIC option to modify our fake libtool scripts such that they pick up the static libstdc++.a. Unfortunately, adding -static-libgcc to those scripts makes libtool barf, so we still have to add that flag to LDFLAGS in build-xorg.

Only try to run the libjpeg-turbo test program if we aren't cross-compiling. In a cross-compile environment, we'll settle for just making sure it compiles and links. Even though that can theoretically produce situations in which the wrong libjpeg is linked, such situations would be exceedingly rare in a cross-compile environment, since there is no "system libjpeg" to accidentally link with.

When we stopped doing full updates on format changes, we also lost the side

Add hack to make the client start properly even in the face of endian issues.
There was a similar hack in the old viewer, so this seems to work well enough

The new viewer stores the framebuffer in a native format, instead of
converting it on each render like the old one. That means we have to change
how we deal with colour maps and make sure it is updated before any changes
to the framebuffer.

Mostly we will catch socket errors when processing incoming data, but
sometimes we'll time it so that a write will be the initial offender. Make

Destroy the main UI and connection objects before popping up the fatal error
message. This avoids a lot of problems with recursion and trying to send
events over a dead socket.
Fix regression. We need to set WIN64 so it will be properly defined in resdefs.h. Failing to do so causes the incorrect manifest file to be included in the Win64 version of WinVNC4.exe, which causes it to fail to run.
