When using `ninja -C "$BUILDDIR"`, ninja prints an annoying log
message about entering the directory that cannot be silenced. Let's
manually move in and out of the build directory instead.
When suspend-then-hibernate is called, hooks have no ability to determine which
stage of the request is being handled; they only see 'pre' and 'post' with the
verb 'suspend-then-hibernate'. This change introduces an environment variable
called SYSTEMD_SLEEP_ACTION that contains the name of the action that is
processing: 'suspend', 'hibernate', 'hybrid-sleep', or
'suspend-after-failed-hibernate'.
Normally ls-files prints the full path to files from the repo root. But when
$GIT_WORK_TREE is set, ls-files prints paths relative to the current
directory. When rebasing, $GIT_WORK_TREE is set in the commands executed from
'rebase -x'. This causes problems if meson config is touched and the meson
reconfigures itself. ($GIT_WORK_TREE shouldn't be relevant, since the paths that
ls-files reports don't depend on the work tree, but whatever.) Let's unset
GIT_WORK_TREE to avoid the issue.

Fixes#18148.
Enhance systemd-networkd to be able to control a CAN device's berr-reporting
flag via the new boolean directive BusErrorReporting= to be used in network
files.
unset-environment is completed with variable names in the environment block.
set-environment the same, but suffixed with "=".
import-environment is completed with variable names in the client environment.
Importing the full environment is convenient, but it doesn't work too well in
practice, because we get a metric ton of shell-specific crap that should never
end up in the global environment block:

Plenty of shell-specific and terminal-specific stuff that have no global
significance.
Let's start warning when this is used to push people towards importing only
specific variables.
Putative NEWS entry:
* systemctl import-environment will now emit a warning when called without
any arguments (i.e. to import the full environment block of the called
program). This command will usually be invoked from a shell, which means
that it'll inherit a bunch of variables which are specific to that shell,
and usually to the tty the shell is connected to, and don't have any
meaning in the global context of the system or user service manager.
Instead, only specific variables should be imported into the manager
environment block.
Similarly, programs which update the manager environment block by directly
calling the D-Bus API of the manager, should also push specific variables,
and not the full inherited environment.
This adds a general description of "philosphy" of keeping the environemnt
block small and hints about systemd-run -P env.
The list of generated variables is split out to a subsection. Viewing
the patch with ignoring whitespace changes is recommended.
We don't ignore invalid assignments (except in import-environment to some
extent), previous description was wrong.

This fixes a bug introduced by ae45e1a383.
The set DnsAnswer::set_items contains the reference to the array in
DnsAnswer. So, the set must be reconstructed when we realloc() the
object.
Fixes#18132.
While we don't support prefix being != /usr, and this is hardcoded
all over the place, variables in pkg-config file are expected
to have overridable base directory.
This is important for at least the following two use cases:
- Installing projects to non-FHS package-specific prefixes for Nix-style
package managers. Of course, it is then their responsibility
to ensure systemd can find the service files.
- Installing to local path for development purposes.
This is a compromise between running a program from a build directory,
and running it fully installed to system prefix.
You will not want to write to system prefix in either case.

- InstallDirectory caches the install part of the build process
which speeds up incremental builds a little and allows inspecting
the installed components in mkosi.installdir.
- SourceFileTransferFinal copies the source files to the final
image which makes the gdb experience in qemu/systemd-nspawn a bit
nicer as it can now find the source files and show the source code
in the gdb cli itself.
