bus-dump: change capture output to use pcapng (#21738)
This patch changes busctl capture to generate pcapng format
instead of the legacy pcap format files. It includes basic
meta-data in the file and still uses microsecond time
resolution. In future, more things can be added such as
high resolution timestams, statistics, etc.
PCAP Next Generation capture file format is what tshark uses
and is in process of being standardized in IETF. It is also
readable with libpcap.

analyze: fix segfault when malloc() fails (#21874)
Fixes #21872.
log_syntax_callback sets 's', a.k.a. '*userdata', to POINTER_MAX to signal allocation failure.
If the error does not cause immediate failure of the program, and log_syntax_callback is called
again, it would try to use 's' as a pointer to a set and fail badly.

boot: Use correct handle to find TextInputEx protocol
LibLocateProtocol will return the protocol for the first device that
supports it. But it may not actually come from the ConIn device that
we want to use here.
This should be the root cause of what was previously considered just
broken firmware. If you ask the wrong device to return some key, of
course it will never provide one.
This changes the way we handle input yet again in light of this new
knowledge and because using the correct TextInputEx with fallback to
ConIn can actually create double input in some cases.
Since we are now confident that we get the right TextInputEx, we can
use that exclusively, only falling back to ConIn if the console input
device does not support the better interface (the spec is pretty clear
that it must support it, though).
Because some firmware is broken, we still need to provide a fallback
to the previously used TextInputEx thats overrides ConIn/ConInEx if
it is functional.

factory: populate /etc/locale.conf with systemd build-time setting
This adds /etc/locale.conf to the set of configuration files
populated by tmpfiles.d factory /etc handling.
In particular, the build-time locale configuration in systemd is
now wired to a /usr factory file, and installed to the system.
On boot, if other locale customization tools did not write
/etc/locale.conf on the system, the factory default file gets
copied to /etc by systemd-tmpfiles.
This is done in order to avoid skews between different system
components when no locale settings are configured. At that point,
systemd can safely act as the fallback owner of /etc/locale.conf.

nss-resolve: expose various source-disablement settings as variables
Fixes https://bugzilla.redhat.com/show_bug.cgi?id=2006761:
> systemd-resolved always (reverse)-resolves the host's IP addresses and FQDN.
> This can be harmful when an application (for instance, a DNS zone manager) is

This allows clients of nss-resolve to use the same config options that are
available through the dbus api and as command-line options to resolvectl.

core: Add trigger limit for path units
When conditions fail on a service unit, a path unit can cause
PID 1 to busy loop as it keeps trying to activate the service unit.
To avoid this from happening, add a trigger limit to the path unit,
identical to the trigger limit we have for socket units.
Initially, let's start with a high limit and not make it configurable.
If needed, we can add properties to configure the rate limit similar
to the ones we have for socket units.
