Added /NOBUILD option to holdingarea/build.bat This allows cmake to be run without subsequently invoking nmake

Moved syborggraphicswrapper from qemu package

Modified CMake scripts to link against correct version of LLVM VISUAL_STUDIO_VERSION must be defined to either 2005 or 2008 when CMake is run. See build.bat for example usage.

Added build script allowing use of different toolchains holdingarea/build.bat provides command-line switches allowing: * Selection between Visual Studio versions (2005 / 2008) * Selection of debug / release builds * Selection of CMake generator (Visual Studio solution / NMake makefiles) * Enabling of miniEGL in the build * Enabling of PlatSim extensions in the build Calling the script with no parameters will start a build using Visual Studio 2005 and nmake.

Added additional builds of LLVM holdingarea/llvm/llvm-2.7 now contains the following builds of LLVM 2.7: * VS2005 debug * VS2005 release * VS2008 debug * VS2008 release Note that only the LLVM libraries are segregated according to compiler and build target. Single copies of the include and bin directories are provided. The LLVM executables are from a VS2005 release build.

Fixup missed changes from frame (buffer) to surface buffer. Change route to qemu syborg.h and memory model includes.

Merge rename of frame buffer to surface buffer with Guest EGL changes.

Rename use of "frame" buffer to "surface" buffer, to reduce confusion.

Minor fix to only exclude c_utils.pyc in the .hgignore file instead of all the vg/bin Python scripts

Fix guestegl to use dynamic framebuffer
