The code incorrectly attempted to use textconv cache when asked,
even when we are not running in a repository, which has been
corrected.

"git difftool --dir-diff" learned to honor the "--trust-exit-code"
option; it used to always exit with 0 and signalled success.
* ps/difftool-dir-diff-exit-code:
git-difftool--helper: honor `--trust-exit-code` with `--dir-diff`
In 9830926c7d (rev-list: add commit object support in `--missing`
option, 2023-10-27) we fixed the `--missing` option in `git rev-list`
so that it works with missing commits, not just blobs/trees.
Unfortunately, such a command was still failing with a "fatal: bad
object <oid>" if it was passed a missing commit, blob or tree as an
argument (before the rev walking even begins). This was fixed in a
recent commit.
That fix still doesn't work when an argument passed to the command is
an annotated tag pointing to a missing commit though. In that case
`git rev-list --missing=...` still errors out with a "fatal: bad
object <oid>" error where <oid> is the object ID of the missing
commit.
Let's fix this issue, and also, while at it, let's add tests not just
for annotated tags but also for regular tags and branches.

Modeling after how the `--no-replace-objects` option is made usable
across subprocess spawning (e.g., cURL based remote helpers are
spawned as a separate process while running "git fetch"), allow the
`--no-lazy-fetch` option to be passed across process boundaries.
Do not model how the value of GIT_NO_REPLACE_OBJECTS environment
variable is ignored, though. Just use the usual git_env_bool() to
allow "export GIT_NO_LAZY_FETCH=0" and "unset GIT_NO_LAZY_FETCH"
to be equivalents.
Also do not model how the request is not propagated to subprocesses
we spawn (e.g. "git clone --local" that spawns a new process to work
in the origin repository, while the original one working in the
newly created one) by the "--no-replace-objects" option, as this "do
not lazily fetch from the promisor" is more about a per-request
debugging aid, not "this repository's promisor should not be relied
upon" property specific to a repository.

prepare_to_commit has some logic to figure out whether merge already
added a scissors line, and therefore it shouldn't add another. Now that
wt_status_add_cut_line has built-in state for whether it has
already added a previous line, just set that state instead, and then
remove that condition from subsequent calls to wt_status_add_cut_line.

`git commit --cleanup=scissors -v` prints two scissors lines:
one at the start of the comment lines, and the other right before the
diff. This is redundant, and pushes the diff further down in the user's
editor than it needs to be.
Make wt_status_add_cut_line() remember if it has added a cut line before,
and avoid adding a redundant one.
Add a test for this.

The reason why we require the <git-compat-util.h> file to be the
first header file to be included is because it insulates other
header files and source files from platform differences, like which
system header files must be included in what order, and what C
preprocessor feature macros must be defined to trigger certain
features we want out of the system.
We tried to clarify the rule in the coding guidelines document, but
the wording was a bit fuzzy that can lead to misinterpretations like
you can include <xdiff/xinclude.h> only to avoid having to include
<git-compat-util.h> even if you have nothing to do with the xdiff
implementation, for example. "You do not have to include more than
one of these" was also misleading and would have been puzzling if
you _needed_ to depend on more than one of these approved headers
(answer: you are allowed to include them all if you need the
declarations in them for reasons other than that you want to avoid
including compat-util yourself).
Instead of using the phrase "approved headers", enumerate them as
exceptions, each labeled with its intended audiences, to avoid such
misinterpretations. The structure also makes it easier to add new
exceptions, so add the description of "t/unit-tests/test-lib.h"
being an exception only for the unit tests implementation as an
example.

This variable is used as the primary way to disable the object
replacement mechanism, with the "--no-replace-objects" command line
option as an end-user visible way to set it, but has not been
documented.
The original reason why it was left undocumented might be because it
was meant as an internal implementation detail, but the thing is,
that our tests use the environment variable directly without the
command line option, and there certainly are folks who learned its
use from there, making it impossible to deprecate or change its
behaviour by now.
Add documentation and note that for this variable, unlike many
boolean-looking environment variables, only the presence matters,
not what value it is set to.
