  tests: add testcases sanity-checking the testsuite
  
  Helper subroutines, variables and other pieces of code defined
  in the `tests/defs' and used by many testcases are non-obvious,
  and tricky to get to work portably; but until now, they weren't
  tested at all in a clear and self-contained way.
  This change should remedy to the situation.
  
  * tests/self-check-cleanup.test: New test, check removal of
  temporary test working directory by `./defs'.
  * tests/self-check-dir.test: New test, check that tests using
  `./defs' create a proper temporary directory, and run in it.
  * tests/self-check-exit.test: New test, check that, in case of
  failing commands, the correct exit status is passed to the exit
  trap installed by the `./defs' script.
  * tests/self-check-is_newest.test: New test, checking the
  `is_newest' subroutine.
  * tests/self-check-me.test: New test, checking that $me gets
  defined automatically by `tests/defs' if not set, and that it
  can be overridden from either the shell or the environment.
  * tests/self-check-sanity.test: New test, check that the sanity
  checks performed by the `tests/defs' script works correctly.
  * tests/self-check-unindent.test: New test, checking the
  `unindent' subroutine.
  * tests/Makefile.am (TESTS): Update.
