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'.

Attempt to handle the differing behavior of Zlib 1.2.3 (which calls deflate(..., Z_PARTIAL_FLUSH) within the body of deflateParams()) and Zlib 1.2.5 (which calls deflate(..., Z_BLOCK)). Not sure why this works, but extensive low-level testing, in which 20 RFB session captures were streamed through an isolated version of the encoder and the compression level was changed randomly, shows this fix to behave solidly with both Zlib versions.

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.

We don't actually need a version number here. This was cruft from back-porting the CMake build script out of libjpeg-turbo 1.1 beta. Removing it because it is, coincidentally, the same as the TigerVNC version number and may cause confusion.

Remove support for building Xvnc against Xorg 7.5. We have fixed the issues that were occurring in the Xorg 7.4 components by upgrading those components. Xorg 7.5 requires autoconf 2.60 and other updated tools that aren't readily available on the legacy platforms we're using with build-xorg (notably: RHEL 4 and 5), and thus no one has successfully built that configuration.

Using build-xorg without -static is not useful, because it causes Xvnc to depend on the dynamic X11 libraries generated by build-xorg in the build directory. Thus, remove -static and make that behavior the default.
The installed package is called "com.tigervnc.tigervnc" (our convention is to use lowercase "tigervnc" for package names), so this fixes an issue whereby it would not uninstall.
Update build documentation to reflect the fact that libjpeg-turbo 32-bit will not build on NASM 0.99 or 2.00 (due to what appears to be a NASM bug, but scant information is available on it), and make the instructions applicable to any NASM version, not just 2.05.

Previous versions of MinGW64 prepended an underscore to the symbol names, which was incompatible with the behavior of Visual C++ 64-bit. MinGW64 1.0 changed its default behavior so that underscores are no longer prepended, so this patch removes the underscores from the SIMD symbol names when building with MinGW64, to prevent the build from breaking. Those wishing to build TigerVNC with older MinGW64 versions will need to add -fno-leading-underscore to CFLAGS and CXXFLAGS.

Don't pretend that vncserver -fg & works, because closing stdin causes problems with some WM's. Instead, just revert to the original vncserver -fg code and add a separate option for auto-killing Xvnc when run in "background" mode.

Using a fixed port range with -via can cause a race condition between multiple vncviewer instances, whereby one instance calls bind() and finds the port to be free, then another instance calls bind() and finds the same port to be free, because the first instance hasn't started the SSH tunnel on it yet. This patch works around the issue by using ephemeral ports. All known modern O/S's increment the ephemeral port number by 1 after bind(), so the port is effectively "reserved" after bind(), and this prevents another vncviewer instance from trying to reserve the same port.
