Some of the tests check the output of rebase is what we expect. These
were added after a regression that added unwanted stash output when
using --autostash. They are useful as they prevent unintended changes to
the output of the various rebase commands. However they also include all
the progress output which is less useful as it only tests what would be
written to a dumb terminal which is not the normal use case. The recent
changes to fix clearing the line when printing progress necessarily
meant making an ugly change to these tests. Address this my removing the
progress output before comparing it to the expected output. We do this
by removing everything before the final "\r" on each line as we don't
care about the progress indicator, but we do care about what is printed
immediately after it.

On native Windows, Git exclusively uses UTF-8 for console output (both
with MinTTY and native Win32 Console). Gettext uses `setlocale()` to
determine the output encoding for translated text, however, MSVCRT's
`setlocale()` does not support UTF-8. As a result, translated text is
encoded in system encoding (as per `GetAPC()`), and non-ASCII chars are
mangled in console output.
Side note: There is actually a code page for UTF-8: 65001. In practice,
it does not work as expected at least on Windows 7, though, so we cannot
use it in Git. Besides, if we overrode the code page, any process
spawned from Git would inherit that code page (as opposed to the code
page configured for the current user), which would quite possibly break
e.g. diff or merge helpers. So we really cannot override the code page.
In `init_gettext_charset()`, Git calls gettext's
`bind_textdomain_codeset()` with the character set obtained via
`locale_charset()`; Let's override that latter function to force the
encoding to UTF-8 on native Windows.
In Git for Windows' SDK, there is a `libcharset.h` and therefore we
define `HAVE_LIBCHARSET_H` in the MINGW-specific section in
`config.mak.uname`, therefore we need to add the override before that
conditionally-compiled code block.
Rather than simply defining `locale_charset()` to return the string
`"UTF-8"`, though, we are careful not to break `LC_ALL=C`: the
`ab/no-kwset` patch series, for example, needs to have a way to prevent
Git from expecting UTF-8-encoded input.

Lately Homebrew learned to automagically clean up information about

for the avarage user, but is a waste of time in CI build jobs, because
the next build jobs will start from the exact same image containing
the same outdated packages anyway.

shaving off about 20-30s from the time needed to install dependencies

Lately our GCC macOS build job on Travis CI has been erroring out
while installing dependencies with:
+brew link gcc@8
Error: No such keg: /usr/local/Cellar/gcc@8
The command "ci/install-dependencies.sh" failed and exited with 1 during .
Now, while gcc@8 is still pre-installed (but not linked) and would be
perfectly usable in the Travis CI macOS image we use [1], it's at
version 8.2. However, when installing dependencies we first
explicitly run 'brew update', which spends over two minutes to update
itself and information about the available packages, and it learns
about GCC 8.3. After that point gcc@8 exclusively refers to v8.3,
and, unfortunately, 'brew' is just too dumb to be able to do anything
with the still installed 8.2 package, and the subsequent 'brew link
gcc@8' fails. (Even 'brew uninstall gcc@8' fails with the same
error!)
Don't run 'brew update' to keep the already installed GCC 8.2 'brew
link'-able. Note that in addition we have to 'export
HOMEBREW_NO_AUTO_UPDATE=1' first, because 'brew' is so very helpful
that it would implicitly run update for us on the next 'brew install
<pkg>' otherwise.
Disabling 'brew update' has additional benefits:
- It shaves off 2-3mins from the ~4mins currently spent on
installing dependencies, and the macOS build jobs have always been
prone to exceeding the time limit on Travis CI.
- Our builds won't suddenly break because of the occasional Homebrew
breakages [2].
The drawback is that we'll be stuck with slightly older versions of
the packages that we install via Homebrew (Git-LFS 2.5.2 and Perforce
2018.1; they are currently at 2.7.2 and 2019.1, respectively). We
might want to reconsider this decision as time goes on and/or switch
to a more recent macOS image as they become available.

git am or rebase have a --skip flag to skip the current commit if the
user wishes to do so. During a cherry-pick or revert a user could
likewise skip a commit, but needs to use 'git reset' (or in the case
of conflicts 'git reset --merge'), followed by 'git (cherry-pick |
revert) --continue' to skip the commit. This is more annoying and
sometimes confusing on the users' part. Add a `--skip` option to make
skipping commits easier for the user and to make the commands more
consistent.

Some tests need to create a string of commits. Doing this with
test_commit is very heavy-weight, as it needs at least one process per
commit (and in fact, uses several).
For bulk creation, we can do much better by using fast-import, but it's
often a pain to generate the input. Let's provide a helper to do so.
We'll use t5310 as a guinea pig, as it has three 10-commit loops. Here
are hyperfine results before and after:
[before]
Benchmark #1: ./t5310-pack-bitmaps.sh --root=/var/ram/git-tests
Time (mean ± σ): 2.846 s ± 0.305 s [User: 3.042 s, System: 0.919 s]
Range (min … max): 2.250 s … 3.210 s 10 runs
[after]
Benchmark #1: ./t5310-pack-bitmaps.sh --root=/var/ram/git-tests
Time (mean ± σ): 2.210 s ± 0.174 s [User: 2.570 s, System: 0.604 s]
Range (min … max): 1.999 s … 2.590 s 10 runs
So we're over 20% faster, while making the callers slightly shorter. We
added a lot more lines in test-lib-function.sh, of course, and the
helper is way more featureful than we need here. But my hope is that it
will be flexible enough to use in more places.

When we receive a remote ref update to sha1 "X", we want to check that
we have all of the objects needed by "X". We can assume that our
repository is not currently corrupted, and therefore if we have a ref
pointing at "Y", we have all of its objects. So we can stop our
traversal from "X" as soon as we hit "Y".
If we make the same non-corruption assumption about any repositories we
use to store alternates, then we can also use their ref tips to shorten
the traversal.
This is especially useful when cloning with "--reference", as we
otherwise do not have any local refs to check against, and have to
traverse the whole history, even though the other side may have sent us
few or no objects. Here are results for the included perf test (which
shows off more or less the maximal savings, getting one new commit and

There's nothing inherently transport-related about enumerating the
alternate ref tips. The code has lived in transport.[ch] because the
only use so far had been advertising available tips during transport.
But it could be used for more, and a future patch will teach rev-list to
access these refs.
Let's move it alongside the other alt-odb code, declaring it in
object-store.h with the implementation in sha1-file.c.
This lets us drop the inclusion of transport.h from receive-pack, which
perhaps shows how it was misplaced (though receive-pack is about
