While we expose macros for most of our different option types understood
by the "parse-options" subsystem, not every combination of fields that
has one as that would otherwise quickly lead to an explosion of macros.
Instead, we just initialize structures manually for those variants of
fields that don't have a macro.
Callsites that open-code these structure initialization don't use
designated initializers though and instead just provide values for each
of the fields that they want to initialize. This has three significant
downsides:
- Callsites need to specify all values up to the last field that they
care about. This often includes fields that should simply be left at
their default zero-initialized state, which adds distraction.
- Any reader not deeply familiar with the layout of the structure
has a hard time figuring out what the respective initializers mean.
- Reordering or introducing new fields in the middle of the structure
is impossible without adapting all callsites.
Convert all sites to instead use designated initializers, which we have
started using in our codebase quite a while ago. This allows us to skip
any default-initialized fields, gives the reader context by specifying
the field names and allows us to reorder or introduce new fields where
we want to.

The `mkdir_in_gitdir()` function is similar to `safe_create_dir()`, but
the former is hosted in "object-file.c" whereas the latter is hosted in

The `null_oid()` function returns the object ID that only consists of
zeroes. Naturally, this ID also depends on the hash algorithm used, as
the number of zeroes is different between SHA1 and SHA256. Consequently,
the function returns the hash-algorithm-specific null object ID.
This is currently done by depending on `the_hash_algo`, which implicitly
makes us depend on `the_repository`. Refactor the function to instead
pass in the hash algorithm for which we want to retrieve the null object
ID. Adapt callsites accordingly by passing in `the_repository`, thus
bubbling up the dependency on that global variable by one layer.
There are a couple of trivial exceptions for subsystems that already got
rid of `the_repository`. These subsystems instead use the repository
that is available via the calling context:
- "builtin/grep.c"
- "grep.c"
- "refs/debug.c"
There are also two non-trivial exceptions:
- "diff-no-index.c": Here we know that we may not have a repository
initialized at all, so we cannot rely on `the_repository`. Instead,
we adapt `diff_no_index()` to get a `struct git_hash_algo` as
parameter. The only caller is located in "builtin/diff.c", where we
know to call `repo_set_hash_algo()` in case we're running outside of
a Git repository. Consequently, it is fine to continue passing
`the_repository->hash_algo` even in this case.
- "builtin/ls-files.c": There is an in-flight patch series that drops
`USE_THE_REPOSITORY_VARIABLE` in this file, which causes a semantic
conflict because we use `null_oid()` in `show_submodule()`. The
value is passed to `repo_submodule_init()`, which may use the object
ID to resolve a tree-ish in the superproject from which we want to
read the submodule config. As such, the object ID should refer to an
object in the superproject, and consequently we need to use its hash
algorithm.
This means that we could in theory just not bother about this edge
case at all and just use `the_repository` in "diff-no-index.c". But
doing so would feel misdesigned.
Remove the `USE_THE_REPOSITORY_VARIABLE` preprocessor define in
"hash.c".

Remove `git_path()` in favor of the `repo_git_path()` family of
functions, which makes the implicit dependency on `the_repository` go
away.
Note that `git_path()` returned a string allocated via `get_pathname()`,
which uses a rotating set of statically allocated buffers. Consequently,
callers didn't have to free the returned string. The same isn't true for
`repo_common_path()`, so we also have to add logic to free the returned
strings.
This refactoring also allows us to remove `repo_common_pathv()` as well

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.

In the run_am() function, we set up a child_process struct to run
"git-am", allocating memory for its args and env strvecs. These are
normally cleaned up when we call run_command(). But if we encounter
certain errors, we exit the function early and try to clean up ourselves
by clearing the am.args field. This leaks the "env" strvec.
We should use child_process_clear() instead, which covers both. And more
importantly, it future proofs us against the struct ever growing more
allocated fields.
These are unlikely errors to happen in practice, so they don't actually
trigger the leak sanitizer in the tests. But we can add a new test which

Inside the function we detect comments by comparing the first byte of a

Setting the rebase.autoSquash config variable to true implies a couple
of restrictions: it prevents preemptive fast-forwarding and it triggers
conflicts with apply backend options. However, it only actually results
in auto-squashing when combined with the --interactive (or -i) option,
due to code in run_specific_rebase() that disables auto-squashing unless
the REBASE_INTERACTIVE_EXPLICIT flag is set.
Doing autosquashing for rebase.autoSquash without --interactive would be
problematic in terms of backward compatibility, but conversely, there is
no need for the aforementioned restrictions without --interactive.
So drop the options.config_autosquash check from the conditions for
clearing allow_preemptive_ff, as the case where it is combined with
--interactive is already covered by the REBASE_INTERACTIVE_EXPLICIT
flag check above it.
Also drop the "apply options are incompatible with rebase.autoSquash"
error, because it is unreachable if it is restricted to --interactive,
as apply options already cause an error when used with --interactive.
Drop the tests for the error from t3422-rebase-incompatible-options.sh,
which has separate tests for the conflicts of --interactive with apply
options.
When neither --autosquash nor --no-autosquash are given, only set
options.autosquash to true if rebase.autosquash is combined with
--interactive.
Don't initialize options.config_autosquash to -1, as there is no need to
distinguish between rebase.autoSquash being unset or explicitly set to
false.
