new feature: rm accepts new option: --one-file-system
Suggested by Steve McIntyre in <http://bugs.debian.org/392925>.

* src/rm.c (rm_option_init): Initialize it.
(usage): Document the option.
* src/mv.c (rm_option_init): Likewise.
* src/remove.c (remove_dir): With --one-file-system and --recursive,
for each directory command line argument, do not affect a file system
different from that of the starting directory. And give a diagnostic.
* src/rm.c (ONE_FILE_SYSTEM): New enum.
(main): Handle new option.
* tests/rm/one-file-system: Test the above.
* tests/rm/Makefile.am (TESTS): Add one-file-system.
* tests/Makefile.am (check-root): Add the rm/one-file-system
test to the list.
(EXTRA_DIST): Add other-fs-tmpdir.
* tests/mv/setup: Removed. Renamed to...
* tests/other-fs-tmpdir: ...this new file.
* tests/mv/Makefile.am (EXTRA_DIST): Remove setup.
* tests/mv/acl: Reflect renaming: use ../other-fs-tmpdir.
