Extensions to rmdir and mkdir utilities * Rework GIT_DIRREMOVAL values to GIT_RMDIR flags, allowing combinations of flags * Add GIT_RMDIR_EMPTY_PARENTS flag to remove parent dirs that are left empty after removal * Add GIT_MKDIR_VERIFY_DIR to give an error if item is a file, not a dir (previously an EEXISTS error was ignored, even for files) and enable this flag for git_futils_mkpath2file call * Improve accuracy of error messages from git_futils_mkdir
