Ævar Arnfjörð Bjarmason 56722a0635 test-lib tests: assert 1 exit code, not non-zero
Improve the testing for test-lib.sh itself to assert that we have a
exit code of 1, not any non-zero. Improves code added in
0445e6f0a1 (test-lib: '--run' to run only specific tests,
2014-04-30).

Ævar Arnfjörð Bjarmason e07b817cfc test-lib tests: refactor common part of check_sub_test_lib_test*()
Refactor the two check_sub_test_lib_test*() functions to avoid
duplicating the same comparison they did of stdout. This duplication
was initially added when check_sub_test_lib_test_err() was added in
0445e6f0a1 (test-lib: '--run' to run only specific tests,
2014-04-30).

Ævar Arnfjörð Bjarmason 12fe4909fa test-lib tests: avoid subshell for "test_cmp" for readability
The use of a sub-shell for running the test_cmp of stdout/stderr for
the test author was introduced in this form in 565b6fa87b (tests:
refactor mechanics of testing in a sub test-lib, 2012-12-16), but from
looking at the history that seemed to have diligently copied my
original ad-hoc implementation in 7b90511970 (t/t0000-basic.sh: Run
the passing TODO test inside its own test-lib, 2010-08-19).

There's no reason to use a subshell here, we try to avoid it in
general. It also improves readability, if the test fails we print out
the relative path in the trash directory that needs to be looked
at.

Before that was mostly obscured, since the "write_sub_test_lib_test"
will pick the directory for you from the test name.

Ævar Arnfjörð Bjarmason c3ff7be6fb test-lib tests: don't provide a description for the sub-tests
Change the $test_description provided for the generated subtests to be
constant, since the only purpose of having it is that test-lib.sh will
barf if it isn't supplied.

The other purpose of having it was to effectively split up the test
description between the argument to test_expect_success and the
argument to "write_and_run_sub_test_lib_test". Let's only use one of
the two.

Ævar Arnfjörð Bjarmason 9f0a45208d test-lib tests: split up "write and run" into two functions
Refactor the function to write and run tests of the test-lib.sh output
into two functions.

When this was added back in 565b6fa87b (tests: refactor mechanics of
testing in a sub test-lib, 2012-12-16) there was no reason to do this,
but since we started supporting test arguments in
517cd55fd5 (test-lib: self-test that --verbose works, 2013-06-23)
we've started to write out duplicate tests simply to test different
arguments, now we'll be able to re-use them.

This change doesn't consolidate any of those tests yet, it just makes
it possible to do so. All the changes in t0000-basic.sh are a simple
search-replacement.

Since the _run_sub_test_lib_test_common() function doesn't handle
running the test anymore we can do away with the sub-shell, which was
used to scope an "unset" and "export" shell variables.

Ævar Arnfjörð Bjarmason 866a3014de test-lib tests: move "run_sub_test" to a new lib-subtest.sh
Move the "check_sub_test_lib_test()" and its sister functions to a new
lib-subtest.sh.

In the future (not in this series) I'd like to test test-lib's output
in a more targeted and smaller test, and I'll need these functions to
do that.
