pretty.c:repo_logmsg_reencode() allocated memory should be freed with
repo_unuse_commit_buffer(). Callers sometimes forgot free it at exit
point. Add `repo_unuse_commit_buffer()` in insert_records_from_trailers
at builtin/shortlog.c and create_commit at builtin/replay.c

The functions die_for_incompatible_opt3() and
die_for_incompatible_opt4() already exist to die whenever a user
specifies three or four options respectively that are not compatible.
Introduce die_for_incompatible_opt2() which dies when two options that
are incompatible are set.

Instead of including USE_THE_REPOSITORY_VARIABLE by default on every
builtin, remove it from builtin.h and add it to all the builtins that
include builtin.h (by definition, that means all builtins/*.c).
Also, remove the include statement for repository.h since it gets
brought in through builtin.h.
The next step will be to migrate each builtin
from having to use the_repository.

In order to reduce the usage of the global the_repository, add a
parameter to builtin functions that will get passed a repository
variable.
This commit uses UNUSED on most of the builtin functions, as subsequent
commits will modify the actual builtins to pass the repository parameter
down.

The `advance_name` variable can either contain a static string when
parsed via the `--advance` command line option or it may be an allocated
string when set via `determine_replay_mode()`. Because we cannot be sure
whether it is allocated or not we just didn't free it at all, resulting
in a memory leak.
Split up the variables such that we can track the static and allocated
strings separately and then free the allocated one to fix the memory
leak.

The documentation claims that "recursive defaults to the diff.algorithm
config setting", but this is currently not the case. This fixes it,
ensuring that diff.algorithm is used when -Xdiff-algorithm is not
supplied. This affects the following porcelain commands: "merge",
"rebase", "cherry-pick", "pull", "stash", "log", "am" and "checkout".
It also affects the "merge-tree" ancillary interrogator.
This change refactors the initialization of merge options to introduce
two functions, "init_merge_ui_options" and "init_merge_basic_options"
instead of just one "init_merge_options". This design follows the
approach used in diff.c, providing initialization methods for
porcelain and plumbing commands respectively. Thanks to that, the
"replay" and "merge-recursive" plumbing commands remain unaffected by
diff.algorithm.

When creating commits via `commit_tree_extended()`, the caller passes in
a string list of parents. This call implicitly transfers ownership of
that list to the function, which is quite surprising to begin with. But
to make matters worse, `commit_tree_extended()` doesn't even bother to
free the list of parents in error cases. The result is a memory leak,
and one that the caller cannot fix by themselves because they do not
know whether parts of the string list have already been released.
Refactor the code such that callers can keep ownership of the list of
parents, which is getting indicated by parameter being a constant
pointer now. Free the lists at the calling site and add a common exit
path to those sites as required.

The replay command is able to replay multiple branches but when some of
them are based on other replayed branches, their commit should be
replayed onto already replayed commits.
For this purpose, let's store the replayed commit and its original
commit in a key value store, so that we can easily find and reuse a
replayed commit instead of the original one.

There is already a 'rebase' mode with `--onto`. Let's add an 'advance' or
'cherry-pick' mode with `--advance`. This new mode will make the target
branch advance as we replay commits onto it.
The replayed commits should have a single tip, so that it's clear where
the target branch should be advanced. If they have more than one tip,
this new mode will error out.

Instead of the fixed "<oldbase> <branch>" arguments, the replay
command now accepts "<revision-range>..." arguments in a similar
way as many other Git commands. This makes its interface more
standard and more flexible.
This also enables many revision related options accepted and
eaten by setup_revisions(). If the replay command was a high level
one or had a high level mode, it would make sense to restrict some
of the possible options, like those generating non-contiguous
history, as they could be confusing for most users.
Also as the interface of the command is now mostly finalized,
we can add more documentation and more testcases to make sure
the command will continue to work as designed in the future.
We only document the rev-list related options among all the
revision related options that are now accepted, as the rev-list
related ones are probably the most useful for now.

We want this command to be a minimal command that just does server side
picking of commits, displaying the results on stdout for higher level
scripts to consume.
So let's simplify it:
* remove the worktree and index reading/writing,
* remove the ref (and reflog) updating,
* remove the assumptions tying us to HEAD, since (a) this is not a
rebase and (b) we want to be able to pick commits in a bare repo,
i.e. to/from branches that are not checked out and not the main
branch,
* remove unneeded includes,
* handle rebasing multiple branches by printing on stdout the update
ref commands that should be performed.
The output can be piped into `git update-ref --stdin` for the ref
updates to happen.
In the future to make it easier for users to use this command
directly maybe an option can be added to automatically pipe its output
into `git update-ref`.

We want replay to be a command that can be used on the server side on
any branch, not just the current one, so we are going to stop updating
HEAD in a future commit.
A "sanity check" that makes sure we are replaying the current branch
doesn't make sense anymore. Let's remove it.

The replay command will be changed in a follow up commit, so that it
will not update refs directly, but instead it will print on stdout a
list of commands that can be consumed by `git update-ref --stdin`.
We don't want this output to be polluted by its current low value
output, so let's just remove the latter.
In the future, when the command gets an option to update refs by
itself, it will make a lot of sense to display a progress meter, but
we are not there yet.

We want to be able to handle signed commits in some way in the future,
but we are not ready to do it now. So for the time being let's just add
a FIXME comment to remind us about it.
These are different ways we could handle them:
- in case of a cli user and if there was an interactive mode, we could
perhaps ask if the user wants to sign again
- we could add an option to just fail if there are signed commits

Let's force the rev walking options we need after calling
setup_revisions() instead of before.
This might override some user supplied rev walking command line options
though. So let's detect that and warn users by:
a) setting the desired values, before setup_revisions(),
b) checking after setup_revisions() whether these values differ from
the desired values,
c) if so throwing a warning and setting the desired values again.
We want the command to work from older commits to newer ones by default.
Also we don't want history simplification, as we want to deal with all
the commits in the affected range.

Let's refactor the code to handle a regular commit (a commit that is
neither a root commit nor a merge commit) into a single function instead
of keeping it inside cmd_replay().
This is good for separation of concerns, and this will help further work
in the future to replay merge commits.

Instead of manually parsing arguments, let's start using the parse_options
API. This way this new builtin will look more standard, and in some
upcoming commits will more easily be able to handle more command line
options.
Note that we plan to later use standard revision ranges instead of
hardcoded "<oldbase> <branch>" arguments. When we will use standard
revision ranges, it will be easier to check if there are no spurious
arguments if we keep ARGV[0], so let's call parse_options() with
PARSE_OPT_KEEP_ARGV0 even if we don't need ARGV[0] right now to avoid
some useless code churn.

For now, this is just a rename from `t/helper/test-fast-rebase.c` into
`builtin/replay.c` with minimal changes to make it build appropriately.
Let's add a stub documentation and a stub test script though.
Subsequent commits will flesh out the capabilities of the new command
and make it a more standard regular builtin.
