to be re-attempted in the next cycle.

When a binary file gets modified and renamed on both sides of history
to different locations, both files would be written to the working

The strftime(3) man page is outside of the Git suite.  Refererence it as

When a9f1f1f9 ("commit-slab.h: code split", 2018-05-19) split
commit-slab.h into commit-slab-decl.h and commit-slab-impl.h header
files, commit-slab-decl.h were left to use "COMMIT_SLAB_HDR_H",
while commit-slab-impl.h gained its own macro, "COMMIT_SLAB_IMPL_H".

As these two files use different include guards, there is nothing
broken, but let's update commit-slab-decl.h to match the convention
to name the include guard after the filename.

This reverts commit 303775a2;
instead of trying to salvage the tap-breaking change, let's
revert the whole thing for now.

A user of progress API calls start_progress() conditionally and
depends on the display_progress() and stop_progress() functions to
become no-op when start_progress() hasn't been called.

As we added a call to trace2_region_enter() to start_progress(), the
calls to other trace2 API calls from the progress API functions must
make sure that these trace2 calls are skipped when start_progress()
hasn't been called on the progress struct.  Specifically, do not
call trace2_region_leave() from stop_progress() when we haven't
called start_progress(), which would have called the matching
trace2_region_enter().

When this developer tested how the git-sdk-64-minimal artifact could be
served to all the GitHub workflow runs that need it, Azure Blobs looked
like a pretty good choice: it is reliable, fast and we already use it in
Git for Windows to serve components like OpenSSL, cURL, etc

It came as an unpleasant surprise just _how many_ times this artifact
was downloaded. It exploded the bandwidth to a point where the free tier
would no longer be enough, threatening to block other, essential Git for
Windows services.

Let's switch back to using the Build Artifacts of our trusty Azure
Pipeline for the time being.

To avoid unnecessary hammering of the Azure Pipeline artifacts, we use
the GitHub Action `actions/upload-artifact` in the `windows-build` job
and the GitHub Action `actions/download-artifact` in the `windows-test`
and `vs-test` jobs (the latter now depends on `windows-build` for that
reason, too).

commit b0a5a12a ("unpack-trees: allow check_updates() to work on a
different index", 2020-03-27) allowed check_updates() to work on a
different index, but it called get_progress() which was hardcoded to
work on o->result much like check_updates() had been.  Update it to also
accept an index parameter and have check_updates() pass that parameter
along so that both are working on the same index.

ccd46945 (date.c: switch to reentrant {gm,local}time_r, 2019-11-28)
removes the only gmtime() call we had and moves to gmtime_r() which
doesn't have the same portability problems.

Remove the compat gmtime code since it is no longer needed, and confirm
by successfull running t4212 in FreeBSD 9.3 amd64 (the oldest I could
get a hold off).

Further work might be needed to ensure 32bit time_t systems (like FreeBSD
i386) will handle correctly the overflows tested in t4212, but that is
orthogonal to this change, and it doesn't change the current behaviour
as neither gmtime() or gmtime_r() will ever return NULL on those systems
because time_t is unsigned.

With a rename/rename(1to2) conflict, we attempt to do a three-way merge
of the file contents, so that the correct contents can be placed in the
working tree at both paths.  If the file is a binary, however, no
content merging is possible and we should just use the original version
of the file at each of the paths.
