Bundle new upstream version of libmv from own branch

This version of libmv includes new gflags and glog libraries which makes
it possible to compile libmv with clang compiler.

Also remove code from CMakeLists which was disabling libmv if using clang.

Tested on linux with gcc-4.6 and clang-3.0, windows cmake+msvc and scons+mingw.
Could be some issues with other platforms/build system which shall be simple to resolve.
