Since [1] running "make coccicheck" has resulted in [2] being emitted
to the *.log files for the "spatch" run, and in the case of "make
coccicheck-test" we'd emit these to the user's terminal.
Nothing was broken as a result, but let's refactor the relevant rules
to eliminate the ambiguity between a possible variable and an
identifier.

Since GNU make 4.4 the semantics of the $(MAKEFLAGS) variable has
changed in a backward-incompatible way, as its "NEWS" file notes:
Previously only simple (one-letter) options were added to the MAKEFLAGS
variable that was visible while parsing makefiles. Now, all options are
available in MAKEFLAGS. If you want to check MAKEFLAGS for a one-letter
option, expanding "$(firstword -$(MAKEFLAGS))" is a reliable way to return
the set of one-letter options which can be examined via findstring, etc.
This upstream change meant that e.g.:
make man
Would become very noisy, because in shared.mak we rely on extracting
"s" from the $(MAKEFLAGS), which now contains long options like
"--jobserver-auth=fifo:<path>", which we'll conflate with the "-s"
option.
So, let's change this idiom we've been carrying since [1], [2] and [3]
as the "NEWS" suggests.
Note that the "-" in "-$(MAKEFLAGS)" is critical here, as the variable
will always contain leading whitespace if there are no short options,
but long options are present. Without it e.g. "make --debug=all" would
yield "--debug=all" as the first word, but with it we'll get "-" as
intended. Then "-s" for "-s", "-Bs" for "-s -B" etc.

A GNU make pattern rule with multiple targets has always meant that
a single invocation of the recipe will build all the targets.
However in older versions of GNU make a recipe that did not really
build all the targets would be tolerated.
Starting with GNU make 4.4 this behavior is deprecated and pattern
rules are expected to generate files to match all the patterns.
If not all targets are created then GNU make will not consider any
target up to date and will re-run the recipe when it is run again.
Modify Documentation/Makefile to split the man page-creating pattern
rule into a separate pattern rule for each pattern.

Python is missing from the default ubuntu-22.04 runner image, which
prevents git-p4 from working. To install python on ubuntu, we need
to provide the correct package names:
* On Ubuntu 18.04 (bionic), "/usr/bin/python2" is provided by the
"python" package, and "/usr/bin/python3" is provided by the "python3"
package.
* On Ubuntu 20.04 (focal) and above, "/usr/bin/python2" is provided by
the "python2" package which has a different name from bionic, and
"/usr/bin/python3" is provided by "python3".
Since the "ubuntu-latest" runner image has a higher version, its
safe to use "python2" or "python3" package name.

There would be a segmentation fault when running p4 v16.2 on ubuntu
22.04 which is the latest version of ubuntu runner image for github
actions.
By checking each version from [1], p4d version 21.1 and above can work
properly on ubuntu 22.04. But version 22.x will break some p4 test
cases. So p4 version 21.x is exactly the version we can use.
With this update, the versions of p4 for Linux and macOS happen to be
the same. So we can add the version number directly into the "P4WHENCE"
variable, and reuse it in p4 installation for macOS.
By removing the "LINUX_P4_VERSION" variable from "ci/lib.sh", the
comment left above has nothing to do with p4, but still applies to
git-lfs. Since we have a fixed version of git-lfs installed on Linux,
we may have a different version on macOS.

When installing p4 as a dependency, we used to pipe output of "p4 -V"
and "p4d -V" to validate the installation and output a condensed version
information. But this would hide potential errors of p4 and would stop
with an empty output. E.g.: p4d version 16.2 running on ubuntu 22.04
causes sigfaults, even before it produces any output.
By removing the pipe after "p4 -V" and "p4d -V", we may get a
verbose output, and stop immediately on errors because we have "set
-e" in "ci/lib.sh". Since we won't look at these trace logs unless
something fails, just including the raw output seems most sensible.

GitHub starts to upgrade its runner image "ubuntu-latest" from version
"ubuntu-20.04" to version "ubuntu-22.04". It will fail to find and
install "gcc-8" package on the new runner image.
Change some of the runner images from "ubuntu-latest" to "ubuntu-20.04"
in order to install "gcc-8" as a dependency.
The first revision of this patch tried to replace "$runs_on_pool" in
"ci/*.sh" with a new "$runs_on_os" environment variable based on the
"os" field in the matrix strategy. But these "os" fields in matrix
strategies are obsolete legacies from commit [1] and commit [2], and
are no longer useful. So remove these unused "os" fields.

When adding an alternate ODB, we check if the alternate has the same
path as the object dir, and if so, we do nothing. However, that
comparison does not resolve symlinks. This makes it possible to add the
object dir as an alternate, which may result in bad behavior. For
example, it can trick "git repack -a -l -d" (possibly run by "git gc")
into thinking that all packs come from an alternate and delete all
objects.
rm -rf test &&
git clone https://github.com/git/git test &&
(
cd test &&
ln -s objects .git/alt-objects &&
# -c repack.updateserverinfo=false silences a warning about not
# being able to update "info/refs", it isn't needed to show the
# bad behavior
GIT_ALTERNATE_OBJECT_DIRECTORIES=".git/alt-objects" git \
-c repack.updateserverinfo=false repack -a -l -d &&
# It's broken!
git status
# Because there are no more objects!
ls .git/objects/pack
)
Fix this by resolving symlinks and relative paths before comparing the
alternate and object dir. This lets us clean up a number of issues noted
in 37a95862c6 (alternates: re-allow relative paths from environment,
2016-11-07):
- Now that we compare the real paths, duplicate detection is no longer
foiled by relative paths.
- Using strbuf_realpath() allows us to "normalize" paths that
strbuf_normalize_path() can't, so we can stop silently ignoring errors
when "normalizing" paths from the environment.
- We now store an absolute path based on getcwd() (the "future
direction" named in 37a95862c6), so chdir()-ing in the process no
longer changes the directory pointed to by the alternate. This is a
change in behavior, but a desirable one.
