Introduce non-deterministic ordering into goal and prerequisite traversal to help tease out inconsistent failures that may happen when running in parallel build mode. Introduce second order into each dependency chain: 1. Existing order is syntactic order reachable via 'dep->next' 2. New order is shuffled order stored as 'dep->shuf' in each 'dep' When updating goals and prerequisites and '--shuffle' is provided, use the shuffled order to walk the graph. When automatic variable are set always use the syntactic order of parameters. * Makefile.am: Add new src/shuffle.c and src/shuffle.h file. * build_w32.bat: Ditto. * builddos.bat: Ditto. * makefile.com: Ditto. * po/POTFILES.in: Ditto. * doc/make.texi: Add documentation for --shuffle. * doc/make.1: Ditto. * src/dep.h (DEP): Add the shuf pointer. * src/filedef.h (struct file): Add was_shuffled flag. * src/main.c: (shuffle_mode): Global flag for the shuffle mode. (usage): Add the --shuffle option. (switches): Ditto. (main): Set shuffle_mode based on the command line parameter. Reshuffle prerequisites if requested. * src/remake.c (update_goal_chain): Walk the shuffled list if enabled. (update_file_1): Ditto. * src/shuffle.h: Provide an interface for shuffling prerequisites. * src/shuffle.c: Implement option parsing and prerequisite shuffling. * tests/scripts/options/shuffle: Test shuffle option and modes.
