Check for chmod, hardlink, symlink, and special character support to prevent test suite failures in feature constrained environments. Thanks to Bruno Haible and Nelson H. F. Beebe for their testing and analysis. * tests/test-lib.sh: Add new feature tests. * tests/hardlinks: Split this hardlinks related test off from tests/remember-backup-files. * tests/Makefile.am (TESTS): Add new hardlinks test here. * tests/file-create-modes, tests/file-modes, tests/read-only-files, tests/preserve-mode-and-timestamp, tests/no-mode-change-git-diff: These tests require chmod support. * tests/hardlinks, tests/unmodified-files: These tests require hardlink support. * tests/symlinks: This test requires symlink support. * tests/quoted-filenames: This test requires special character support in filenames.
