Finish the removal I started in 1108cea7f8e (tests: remove most uses
of test_i18ncmp, 2021-02-11). At that time the function wasn't removed
due to disruption with in-flight changes, remove the occurrences that
have landed since then.
As of writing this there are no test_i18ncmp uses between "master" and
"seen", so let's also remove the function to finally put it to rest.

When serving a clone or fetch with bitmaps, after deciding which objects
need to be sent our "pack reuse" mechanism kicks in: we try to send
more-or-less verbatim a bunch of objects from the beginning of the
bitmapped packfile without even adding them to the to_pack.objects
array.
After deciding which objects will be in the "reused" portion, we update
nr_result to account for those, and then trigger display_progress() to
show the user (who is undoubtedly dazzled that we managed to enumerate
so many objects so quickly).
But then something confusing happens: the "Enumerating objects" progress
meter jumps _backwards_, counting up from zero the number of objects we
actually add into to_pack.objects.
This worked correctly once upon a time, but was broken in 5af050437a
(pack-objects: show some progress when counting kept objects,
2018-04-15), when the latter half of that progress meter switched to
using a separate nr_seen counter, rather than nr_result. Nobody noticed
for two reasons:
- prior to the pack-reuse fixes from a14aebeac3 (Merge branch
'jk/packfile-reuse-cleanup', 2020-02-14), the reuse code almost
never kicked in anyway
- the output looks _kind of_ correct. The "backwards" moment is hard
to catch, because we overwrite the old progress number with the new
one, and the larger number is displayed only for a second. So unless
you look at that exact second, you just see the much smaller value,
counting up to the number of non-reused objects (though of course if
you catch it in stderr, or look at GIT_TRACE_PACKET from a server
with bitmaps, you can see both values).
This smaller output isn't wrong per se, but isn't counting what we ever
intended to. We should give the user the whole number of objects we
considered (which, as per 5af050437a's original purpose, is already
_not_ a count of what goes into to_pack.objects). The follow-on
"Counting objects" meter shows the actual number of objects we feed into
that array.
We can easily fix this by bumping (and showing) nr_seen for the
pack-reused objects. When the included test is run without this patch,
the second pack-objects invocation produces "Enumerating objects: 1" to
show the one loose object, even though the resulting pack has hundreds
of objects in it. With it, we jump to "Enumerating objects: 674" after
deciding on reuse, and then "675" when we add in the loose object.

versions could be an empty string_list. In that case, versions->items is
NULL, and we shouldn't be trying to perform pointer arithmetic with it (as
that results in undefined behaviour).
Moreover we only use the results of this calculation once when calling
QSORT. Therefore we choose to skip creating relevant_entries and call
QSORT directly with our manipulated pointers (but only if there's data
requiring sorting). This lets us avoid abusing the string_list API,
and saves us from having to explain why this abuse is OK.
Finally, an assertion is added to make sure that write_tree() is called
with a valid offset.
This issue has probably existed since:
ee4012dcf9 (merge-ort: step 2 of tree writing -- function to create tree object, 2020-12-13)
But it only started occurring during tests since tests started using
merge-ort:
f3b964a07e (Add testing with merge-ort merge strategy, 2021-03-20)
For reference - here's the original UBSAN commit that implemented this
check, it sounds like this behaviour isn't actually likely to cause any
issues (but we might as well fix it regardless):

In send_fetch_request(), "object-format" is written directly to the file
descriptor, as opposed to the other arguments, which are buffered.
Buffer "object-format" as well. "object-format" must be buffered; in
particular, it must appear after "command=fetch" in the request.
This divergence was introduced in 4b831208bb ("fetch-pack: parse and
advertise the object-format capability", 2020-05-27), perhaps as an
oversight (the surrounding code at the point of this commit has already
been using a request buffer.)

Gitweb extracts content from the Git log and makes it accessible
over HTTP. As a result, e-mail addresses found in commits are
exposed to web crawlers and they may not respect robots.txt.
This can result in unsolicited messages.
Introduce an 'email-privacy' feature which redacts e-mail addresses
from the generated HTML content. Specifically, obscure addresses
retrieved from the the author/committer and comment sections of the
Git log. The feature is off by default.
This feature does not prevent someone from downloading the
unredacted commit log, e.g., by cloning the repository, and
extracting information from it. It aims to hinder the low-
effort, bulk collection of e-mail addresses by web crawlers.

Add a diff driver for Scheme-like languages which recognizes top level
and local `define` forms, whether it is a function definition, binding,
syntax definition or a user-defined `define-xyzzy` form.
Also supports R6RS `library` forms, `module` forms along with class and
struct declarations used in Racket (PLT Scheme).
Alternate "def" syntax such as those in Gerbil Scheme are also
supported, like defstruct, defsyntax and so on.
The rationale for picking `define` forms for the hunk headers is because
it is usually the only significant form for defining the structure of
the program, and it is a common pattern for schemers to have local
function definitions to hide their visibility, so it is not only the top
level `define`'s that are of interest. Schemers also extend the language
with macros to provide their own define forms (for example, something
like a `define-test-suite`) which is also captured in the hunk header.
Since it is common practice to extend syntax with variants of a form
like `module+`, `class*` etc, those have been supported as well.
The word regex is a best-effort attempt to conform to R7RS[1] valid
identifiers, symbols and numbers.

Simplify the test added in 9466e3809d (blame: enable funcname blaming
with userdiff driver, 2020-11-01) to use the --author support recently
added in 999cfc4f45 (test-lib functions: add --author support to
test_commit, 2021-01-12).
We also did not need the full fortran-external-function content. Let's
cut it down to just the important parts.
I'm modifying it to demonstrate that the fortran-specific userdiff
function is in effect by adding "DO NOT MATCH ..." and "AS THE ..."
lines surrounding the "RIGHT" one.
This is to check that we're using the userdiff "fortran" driver, as
opposed to the default driver which would match on those lines as part
of the general heuristic of matching a line that doesn't begin with
whitespace.
The test had also been leaving behind a .gitattributes file for later
tests to possibly trip over, let's clean it up with
"test_when_finished".
