This adds a new flag JSON_FORMAT_OFF that is a marker for "no JSON
output please!".
Of course, this flag sounds pointless in a JSON implementation, however
this is useful in code that can generate JSON output, but also more
human friendly output (for example our table formatters).
With this in place various tools that so far maintained one boolean
field "arg_json" that controlled whether JSON output was requested at
all and another field "arg_json_format_flags" for selecing the precise
json output flags may merge them into one, simplifying code a bit.
When building with Clang and using structured initialization, the
bpf_attr union is not zero-padded, so the kernel misdetects it as
an unsupported extension.
zero it until Clang's behaviour matches GCC. Do not skip the test
on Github Actions anymore.
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'.
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.
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 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.

Partially reverts 6e65df89c3
commit 15d7ab87c4 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'.

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.
