[parted-devel] Rewrite integration tests to use a new framework
(git's).

My first cut at adding integration tests didn't communicate well
what was being tested. I've redone the framework to be more chatty,
a lot like git's. Here's the output from "make -C tests check":
---------------------------------------------
Making check in tests
make[1]: Entering directory `/f/mirror/parted/b/tests'
make check-TESTS
make[2]: Entering directory `/f/mirror/parted/b/tests'
* ok 1: create the test file
* ok 2: run parted -s FILE mklabel msdos
* ok 3: expect no output
* ok 4: erase the left-over label
* ok 5: run parted mklabel (without -s) on a blank disk
* ok 6: create expected output file
* ok 7: check its "interactive" output
* ok 8: create interactive input
* ok 9: rerun that same command, but now with a preexisting label
* ok 10: normalize the actual output
* ok 11: create expected output file
* ok 12: check its output -- slightly different here, due to prompts
* passed all 12 test(s)
PASS: t0000-basic.sh
* ok 1: create a file too small to hold a fat32 file system
* ok 2: label the test disk
* ok 3: expect no output
* ok 4: try/fail to create a file system in too small a space
* ok 5: create expected output file
* ok 6: check for expected failure diagnostic
* ok 7: clean up, preparing for next test
* ok 8: create a file large enough to hold a fat32 file system
* ok 9: label the test disk
* ok 10: expect no output
* ok 11: create an msdos file system
* ok 12: expect no output
* passed all 12 test(s)
PASS: t1000-mkpartfs.sh
==================
All 2 tests passed
==================
---------------------------------------------
You can get still more output by running the tests
individually with e.g., --verbose or --debug.
That reminds me I need to add a tests/README file.
I'll do that once this goes in.
Here's the patch (looks big, but most of it is removals):

Rewrite integration tests to use a new framework (git's).
* tests/t1000-mkpartfs.sh: New file.
* tests/t0000-basic.sh: New file.
* tests/test-lib.sh: New file. Derived from git's t/test-lib.sh.
* tests/lang-default, tests/priv-check: Remove files.
* tests/Makefile.am (EXTRA_DIST): Add test-lib.sh.
Remove lang-default and priv-check; no longer used.
* tests/part-01, tests/label-01: Remove files.
* tests/part-02, tests/label-02: Likewise.
