systemd-sleep: Set SYSTEMD_SLEEP_ACTION for systemd-sleep hooks.
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.

network: can: add support for bus error reporting

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.

pkg-config: make prefix overridable again
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.

mkosi: Enable InstallDirectory and SourceFileTransferFinal options
- 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.

networkd: Enable IPv6SendRA on builtin network files
RAs trigger neighbor discovery which allows users to query the
LL address of the container/VM via `ip neighbor get dev`. This is
useful as it gives users an easy way to connect to the container
without needing LLMNR or mDNS to resolve the hostname of the container
to an IP address. In practice, this allows connecting with only
networkd enabled and without resolved running in the host/container.

systemctl: have is-enabled return success for aliases when calling into pid1 too
commit 15d7ab87c4e5917f5788f1f8dce327a1e272bea3 introduced the
change to add an 'alias' state, but it was wired to systemctl
only when running in 'client-side' mode. Return success as
expected and documented also when running in 'server-mode'.
string-util: use GREEDY_ALLOC_ROUND_UP() in strextend()
This uses GREEDY_ALLOC_ROUND_UP() to grow the allocation size
exponentially. This should speed allocation loops up a bit, given
that we often call strextend() repeatedly in a loop on the same
buffer.

the home directory instead. (systemd-tmpfiles-setup.service is ordered
