Let's drop stuff from the current $BUILD_DIR from the final coverage
report, as it's all generated files (mostly gperf) which we don't
really care about and it makes the Coveralls report confusing, since it
reports "source not available" for all such files.
When running on Debian/Ubuntu, I get a minute delay or so on every boot
because the local initramfs tries to resume from hibernation. This is
not really useful here, so always skip it
This gets rid of the all-but-one remaining uses of perl. I tested the new code
on my machine, so I'm fairly confident that it works as expected.
install_iscsi() has one majestic perl invocation, but we can't get rid of it
easily: it extends the code of tgt-admin to print some list of files. Obviously
this only works because tgt-admin is written in perl, and perl will be installed
if tgt-admin is installed. install_iscsi() is used in TEST-64-UDEV-STORAGE
conditionally if tgtadm is installed, so this can stay as is.
Stripping the binaries in the test images makes potential stack straces
quite useless, so let's drop the stripping stuff to make test fails a bit
more developer friendly.

Let's make the dropin, to make the build dir writable for gcov, a bit
more generic, so it can be used by all units starting with prefix test-.
This should help with a bunch of recent reports about missing coverage I
got, as well as with existing test units using DynamicUser=true.
This might feel a bit like a magic trick from behind the curtains, but I
want to touch the actual tests as little as possible, since it makes them
unnecessarily messy (see the various workarounds for sanitizers), and
the coverage reports are generated only in a specific CI job anyway.
systemd-repart needs to find mkfs.ext4 for the test.
This is located in the directory /usr/sbin on openSUSE Tumbleweed.
But since the variable ALWAYS_SET_PATH in /etc/login.defs is set to yes,
su re-initializes the $PATH variable and removes /usr/sbin.
Hence, mkfs.ext4 is not found and the test fails.
Using setpriv instead of su fixes this issue and is more appropriate to
do the switch user task from root.
[zjs: move setpriv to $BASICTOOLS and force-push to retrigger CI]
This is useful to identify log messages with metadata from the images
they run on. Look for ID/VERSION_ID/IMAGE_ID/IMAGE_VERSION/BUILD_ID,
with a SYSEXT_ prefix if we are looking at an extension, and append via
LogExtraFields= as respectively PORTABLE_NAME_AND_VERSION= in case of a
single image. In case of extensions, append as PORTABLE_ROOT_NAME_AND_VERSION=
for the base and one PORTABLE_EXTENSION_AND_VERSION= for each extension.
Example with a base and two extensions, with the unit coming from the
first extension:
[Service]
RootImage=/home/bluca/git/systemd/base.raw
Environment=PORTABLE=app0.raw
BindReadOnlyPaths=/etc/os-release:/run/host/os-release
LogExtraFields=PORTABLE=app0.raw
Environment=PORTABLE_ROOT=base.raw
LogExtraFields=PORTABLE_ROOT=base.raw
LogExtraFields=PORTABLE_ROOT_NAME_AND_VERSION=debian_10
ExtensionImages=/home/bluca/git/systemd/app0.raw
LogExtraFields=PORTABLE_EXTENSION=app0.raw
LogExtraFields=PORTABLE_EXTENSION_NAME_AND_VERSION=app_0
ExtensionImages=/home/bluca/git/systemd/app1.raw
LogExtraFields=PORTABLE_EXTENSION=app1.raw
LogExtraFields=PORTABLE_EXTENSION_NAME_AND_VERSION=app_1
When testing the binaries from the host, make sure to not store the state data
below /usr but use a dedicated directory in /var/tmp/ instead.
The working directories of the tests, initially located in /var/tmp, are also
moved in a dedicated directory /var/tmp/systemd-tests.
I noticed that our coverage reports miss some files completely - this
happens when the test doesn't touch the code in them at all, so the
generated coverage data (and resulting reports) have no information
about them. Let's fix this by doing an initial zero coverage capture
that contains a zeroed counter for every instrumented line in every
file, so when we later merge it with a capture from the test, it shows up
with a missing coverage instead of not showing at all.
/usr/lib/systemd/tests may contain more than the unit tests. For example on
SUSE we also install the integration tests there.
Putting the unit tests in a dedicated directory named 'unit-tests' makes the
layout cleaner.
Note that `run-unit-tests.py` has not been moved so we don't need to adjust
(Fedora) packaging and users also don't need to descend into the subdirectory.
Let's attempt to reduce the amount of flakes further when the AWS region
we run in is under heavy load and the hypervisor stars stealing our CPU
time.

(The one case that is left unchanged is '< <(subcommand)'.)
This way, the style with no gap was already dominant. This way, the reader
immediately knows that ' < ' is a comparison operator and ' << ' is a shift.
In a few cases, replace custom EOF replacement by just EOF. There is no point
in using someting like "_EOL" unless "EOF" appears in the text.
On Arch both delv and dig pull in libnss_resolve:
```
$ grep resolve /etc/nsswitch.conf
hosts: mymachines resolve [!UNAVAIL=return] files myhostname dns
```
Since c78d18215b D-Bus services now have 60s to start, but the client
side (sd-bus) still waits only for 25s before giving up:

Let's override the timeout in sd-bus as well to mitigate this.
