The `orderfile` diff option is being assigned via `OPT_FILENAME()`,
which assigns an allocated string to the variable. We never free it
though, causing a memory leak.
Change the type of the string to `char *` and free it to plug the leak.
This also requires us to use `xstrdup()` to assign the global config to
it in case it is set.
This leak is being hit in t7621, but plugging it alone does not make the
test suite pass.

The `opt_ff` field gets populated either via `OPT_PASSTHRU` via
`config_get_ff()` or when `--rebase` is passed. So we sometimes end up
overriding the value in `opt_ff` with another value, but we do not free
the old value, causing a memory leak.
Adapt the type of the variable to be `char *` and consistently assign
allocated strings to it such that we can easily free it when it is being
overridden.

In `treat_directory()` we perform some logic to handle ignored and
untracked entries. When populating a directory with entries we first
save the current number of ignored/untracked entries and then populate
new entries at the end of our arrays that keep track of those entries.
When we figure out that all entries have been ignored/are untracked we
then remove this tail of entries from those vectors again. But there is
an off by one error in both paths that causes us to not free the first
ignored and untracked entries, respectively.
Fix these off-by-one errors to plug the resulting leak. While at it,
massage the code a bit to match our modern code style.

When `update_submodule()` fails we return with `die_message()`, which
only causes us to print the same message as `die()` would without
actually causing the process to die. We don't free memory in that case
and thus leak memory.
Fix the leak by freeing the remote ref.

In the "submodule-nested-repo-config" helper we create a submodule

In `runcommand_in_submodule_cb()` we may end up not executing the child
command when `argv` is empty. But we still populate the command with
environment variables and other things, which needs cleanup. This leads
to a memory leak because we do not call `finish_command()`.
Fix this by clearing the child process when we don't execute it.

In `handle_builtin()` we may end up creating an ad-hoc argv array in
case we see that the command line contains the "--help" parameter. In
this case we observe two memory leaks though:
- We leak the `struct strvec` itself because we directly exit after
calling `run_builtin()`, without bothering about any cleanups.
- Even if we free'd that vector we'd end up leaking some of its
strings because `run_builtin()` will modify the array.
Plug both of these leaks.

The `html_path` variable gets populated via `git_help_config()`, which
puts an allocated string into it if its value has been configured. We do
not clear the old value though, which causes a memory leak in case the
config exists multiple times.
Plug this leak. The leak is exposed by t0012, but plugging it alone is
not sufficient to make the test suite pass.

In `get_html_page_path()` we may end up assigning the return value of
`system_path()` to the global `html_path` variable. But as we also
assign the returned value to `to_free`, we will deallocate its memory
upon returning from the function. Consequently, `html_path` will now
point to deallocated memory.
Fix this issue by instead assigning the value to a separate local
variable.
