Ævar Arnfjörð Bjarmason 892e6f7ea6 test-lib: make test_expect_code a test command 
Change test_expect_code to be a normal test command instead of a
top-level command.

As a top-level command it would fail in cases like:

    test_expect_code 1 'phoney' '
        foo && bar && (exit 1)
    '

Here the test might incorrectly succeed if "foo" or "bar" happened to
fail with exit status 1. Instead we now do:

    test_expect_success 'phoney' '
        foo && bar && test_expect_code 1 "(exit 1)"
    '

Which will only succeed if "foo" and "bar" return status 0, and "(exit
1)" returns status 1.  Note that test_expect_code has been made slightly
noisier, as it reports the exit code it receives even upon success.

Some test code in t0000-basic.sh relied on the old semantics of
test_expect_code to test the test_when_finished command. I've
converted that code to use an external test similar to the TODO test I
added in v1.7.3-rc0~2^2~3.

test_description='Test the very basics part #1.
The rest of the test suite does not check the basic operation of git
plumbing commands to work very carefully. Their job is to concentrate
on tricky features that caused bugs in the past to detect regression.
This test runs very basic features, like registering things in cache,
writing tree, etc.
Note that this test *deliberately* hard-codes many expected object
IDs. When object ID computation changes, like in the previous case of
swapping compression and hashing order, the person who is making the
modification *should* take notice and update the test vectors here.
