ENH: Add RecurseThroughSymlinks data member to kwsys::Glob. Allows recursive globs to skip symlinks when necessary. Default to true for backwards compatible behavior. Used from the ctest coverage handler to avoid recursing through the '/Applications' directory on the Mac looking for *.da files... Should fix the hangs reported recently by Mac CMake dashboard submitters.
