If "git rebase" fails to start after stashing the user's uncommitted
changes then it forgets to restore the stashed changes and remove the
state directory. To make matters worse, running "git rebase --abort" to
apply the stashed changes and cleanup the state directory fails because
the state directory only contains the "autostash" file and is missing
the "head-name" and "onto" files required by read_basic_state().
Fix this by applying the autostash and removing the state directory if
the pre-rebase hook or initial checkout fail. This matches what
finish_rebase() does at the end of a successful rebase. If the user
modifies any files after the autostash is created it is possible there
will be conflicts when the autostash is applied. In that case
apply_autostash() saves the stash in a new entry under refs/stash and so
it is safe to remove the state directory containing the autostash file.
New tests are added to check the autostash is applied and the state
directory is removed if the rebase fails to start. Checks are also added
to some existing tests in order to ensure there is no state directory
left behind when a rebase fails to start and no autostash has been
created.

Call graph_clear() in release_revisions(), this will free memory
allocated by e.g. this command, which will now run without memory
leaks:
git -P log -1 --graph --no-graph --graph

Make use of "test_hook" in various cases that didn't fit neatly into
preceding commits. Here we need to indent blocks in addition to
changing the test code, or to make other small cosmetic changes.

Carefully excluding t3404, which sees independent development elsewhere
at the time of writing, we use `main` as the default branch name in
t34*. This trick was performed via
$ (cd t &&
sed -i -e 's/master/main/g' -e 's/MASTER/MAIN/g' \
-e 's/Master/Main/g' -- t34*.sh &&
git checkout HEAD -- t34\*)
This allows us to define `GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=main`
for those tests.

In addition to the manual adjustment to let the `linux-gcc` CI job run
the test suite with `master` and then with `main`, this patch makes sure
that GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME is set in all test scripts
that currently rely on the initial branch name being `master by default.
To determine which test scripts to mark up, the first step was to
force-set the default branch name to `master` in
- all test scripts that contain the keyword `master`,
- t4211, which expects `t/t4211/history.export` with a hard-coded ref to
initialize the default branch,
- t5560 because it sources `t/t556x_common` which uses `master`,
- t8002 and t8012 because both source `t/annotate-tests.sh` which also
uses `master`)
This trick was performed by this command:
$ sed -i '/^ *\. \.\/\(test-lib\|lib-\(bash\|cvs\|git-svn\)\|gitweb-lib\)\.sh$/i\
GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\
export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\
' $(git grep -l master t/t[0-9]*.sh) \
t/t4211*.sh t/t5560*.sh t/t8002*.sh t/t8012*.sh
After that, careful, manual inspection revealed that some of the test
scripts containing the needle `master` do not actually rely on a
specific default branch name: either they mention `master` only in a
comment, or they initialize that branch specificially, or they do not
actually refer to the current default branch. Therefore, the
aforementioned modification was undone in those test scripts thusly:
$ git checkout HEAD -- \
t/t0027-auto-crlf.sh t/t0060-path-utils.sh \
t/t1011-read-tree-sparse-checkout.sh \

We excluded one set of test scripts in these commands, though: the range
of `git p4` tests. The reason? `git p4` stores the (foreign) remote
branch in the branch called `p4/master`, which is obviously not the
default branch. Manual analysis revealed that only five of these tests
actually require a specific default branch name to pass; They were
modified thusly:
$ sed -i '/^ *\. \.\/lib-git-p4\.sh$/i\
GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME=master\
export GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME\
' t/t980[0167]*.sh t/t9811*.sh

Ordinarily, we would say "VAR=VAL command" to execute a tested
command with environment variable(s) set only for that command.
This however does not work if 'command' is a shell function (most
notably 'test_must_fail'); the result of the assignment is retained
and affects later commands.
To avoid this, we used to assign and export environment variables
and run such a test in a subshell, like so:
(
VAR=VAL && export VAR &&
test_must_fail git command to be tested
)
But with "env" utility, we should be able to say:
test_must_fail env VAR=VAL git command to be tested
which is much shorter and easier to read.

In order to selectively skip tests, the environment variable GIT_SKIP_TESTS
can be set like this:
$ GIT_SKIP_TESTS='t1301 t4150.18' make test
That is, its value can contain only the test script numbers, but not the
full script name. Therefore, it is important that the test scripts are
uniquely numbered. This makes it so.
