[PATCH] CMake add_version_info_from_vcs SVN_REPOSITORY

This will be used by Clang to show full build information when
LLVM_APPEND_VC_REV is enabled and LLVM/Clang are built from Git.

Also try to figure-out repository URL and revision from Git mirror parsing
git-svn-id: footer from last commit (if present).

LLVM patches should go to the llvm-commits list, not llvmdev.

Paul, thank you for pointing that out. Next time I will be more careful about reading submitting guidelines.

Cheers,
