fast-rebase: demonstrate merge-ort's API via new test-tool command
Add a new test-tool command named 'fast-rebase', which is a
super-slimmed down and nowhere near as capable version of 'git rebase'.
'test-tool fast-rebase' is not currently planned for usage in the
testsuite, but is here for two purposes:
1) Demonstrate the desired API of merge-ort. In particular,
fast-rebase takes advantage of the separation of the merging
operation from the updating of the index and working tree, to
allow it to pick N commits, but only update the index and working
tree once at the end. Look for the calls to
merge_incore_nonrecursive() and merge_switch_to_result().
2) Provide a convenient benchmark that isn't polluted by the heavy
disk writing and forking of unnecessary processes that comes from
sequencer.c and merge-recursive.c. fast-rebase is not meant to
replace sequencer.c, just give ideas on how sequencer.c can be
changed. Updating sequencer.c with these goals is probably a
large amount of work; writing a simple targeted command with
no documentation, less-than-useful help messages, numerous
limitations in terms of flags it can accept and situations it can
handle, and which is flagged off from users is a much easier
interim step.

merge-ort-wrappers: new convience wrappers to mimic the old merge API
There are a few differences between the new API in merge-ort and the old
API in merge-recursive. While the new API is more flexible, it might
feel like more work at times than the old API. merge-ort-wrappers
creates two convenience wrappers taking the exact same arguments as the
old merge_trees() and merge_recursive() functions and implements them
via the new API. This makes converting existing callsites easier, and
serves to highlight some of the differences in the API.

merge-ort: barebones API of new merge strategy with empty implementation
This is the beginning of a new merge strategy. While there are some API
differences, and the implementation has some differences in behavior, it
is essentially meant as an eventual drop-in replacement for
merge-recursive.c. However, it is being built to exist side-by-side
with merge-recursive so that we have plenty of time to find out how
those differences pan out in the real world while people can still fall
back to merge-recursive. (Also, I intend to avoid modifying
merge-recursive during this process, to keep it stable.)
The primary difference noticable here is that the updating of the
working tree and index is not done simultaneously with the merge
algorithm, but is a separate post-processing step. The new API is
designed so that one can do repeated merges (e.g. during a rebase or
cherry-pick) and only update the index and working tree one time at the
end instead of updating it with every intermediate result. Also, one
can perform a merge between two branches, neither of which match the
index or the working tree, without clobbering the index or working tree.
The next three commits will demonstrate various uses of this new API.

SKIP_DASHED_BUILT_INS: do not skip the bin/ programs
The idea of the `SKIP_DASHED_BUILT_INS` option is to stop hard-linking
the built-in commands as separate executables. The patches to do that
specifically excluded the three commands `receive-pack`,
`upload-archive` and `upload-pack`, though: these commands are expected
to be present in the `PATH` in their dashed form on the server side of
any fetch/push.
However, due to an oversight by myself, even if those commands were
still hard-linked, they were not installed into `bin/`.

a tool tip is showing, the tool tip will stay there forever (in front of

When `master` is tagged, and then both `master` and the tag are pushed,
Travis CI will happily build both. That is a waste of energy, which is
why we skip the build for `master` in that case.
Our GitHub workflow is also triggered by tags. However, the run would
fail because the `windows-test` jobs are _not_ skipped on tags, but the
`windows-build` job _is skipped (and therefore fails to upload the
build artifacts needed by the test jobs).
In addition, we just added logic to our GitHub workflow that will skip
runs altogether if there is already a successful run for the same commit
or at least for the same tree.
Let's just change the GitHub workflow to no longer specifically skip
tagged revisions.

Commit f08cbf60fe (index-pack: make quantum of work smaller, 2020-09-08)
refactored the main loop in threaded_second_pass(), but also deleted the
call to display_progress() at the top of the loop. This means that users
typically see no progress at all during the delta resolution phase (and
for large repositories, Git appears to hang).
This looks like an accident that was unrelated to the intended change of
that commit, since we continue to update nr_resolved_deltas in
resolve_delta(). Let's restore the call to get that progress back.
We'll also add a test that confirms we generate the expected progress.
This isn't perfect, as it wouldn't catch a bug where progress was
delayed to the end. That was probably possible to trigger when receiving
a thin pack, because we'd eventually call display_progress() from
fix_unresolved_deltas(), but only once after doing all the work.
However, since our test case generates a complete pack, it reliably
demonstrates this particular bug and its fix. And we can't do better
without making the test racy.

won't use it.

colored and the hard-coded ones are still light. This defeats the
purpose of applying the theme and makes the UI look very awkward.
Remove the hard-coded colors in ttext calls and use colors from the
theme for those widgets via Text.Background and Text.Foreground from the

Similarly, the highlighting for the currently selected file(s) in the
"Staged Files" and "Unstaged Files" sections is also hard-coded. Pull
the colors for that from the current theme to make sure it is in line
On atomic pushing failure with GnuPG, we expect a very specific output
in stdout due to `--porcelain` switch.
On such failure, we also write down some helpful hint into stderr
in order to help user understand what happens and how to continue from
those failures.
On a lot of system, those hint (in stderr) will be flushed first,
then those messages in stdout will be flushed. In such systems, the
current test code is fine as is.
However, we don't have such guarantee, (at least) there're some real
systems that writes those stream interleaved. On such systems, we may
see the stderr stream written in the middle of stdout stream.
Let's split those stream redirection. By splitting those stream,
the output stream will contain exactly what we want to compare,
thus, saving us a "sed" invocation.
While we're at it, change the `test_i18ncmp` to `test_cmp` because we
