Show hidden images in the completion results, but only if the current

- `machinectl clone .<Tab>` will offer both hidden and non-hidden images
If there are name collisions in the leds subsystem, the 2nd device node with the
colliding name gets automatically renamed by appending _1, the third by
appending _2 and so on.
This wildcard change makes sure that systemd-backlight also catches these
renamed nodes for kbd_backlight entries.
Log about missing executor at the emergency level, so the message always
makes it to the console - otherwise it won't get anywhere, since we
can't even start systemd-journald in that case.

The RA's Retransmission Timer field was being ignored. This resolves the IPv6
Core Conformance test, v6LC.2.1.5 [1].
Retransmission Timer is a 32-bit unsigned integer. The time, in milliseconds,
between retransmitted Neighbor Solicitation messages. Used by the Address
Resolution and Neighbor Unreachability Detection (NUD) algorithm.
Support setting a default value for the neighbour retransmission timer value with:
[Network]
IPv6RetransmissionTimeSec=<int>
By default, upon receiving a Router Advertisement with the Retransmission Timer
field set to a non-zero value, it will update the kernel's retransmit timer value.
To disable this behaviour, configure the UseIPv6RetransmissionTime= under the
[IPv6AcceptRA] section.
[IPv6AcceptRA]
UseIPv6RetransmissionTime=<bool>
RFC4861: Neighbor Discovery in IPv6
* Section 4.2 RA Message Format.
* Section 6.3.4 Processing Received Router Advertisements
A Router Advertisement field (e.g., Cur Hop Limit, Reachable Time,
and Retrans Timer) may contain a value denoting that it is
unspecified. In such cases, the parameter should be ignored and the
host should continue using whatever value it is already using. In
particular, a host MUST NOT interpret the unspecified value as
meaning change back to the default value that was in use before the
first Router Advertisement was received.
The RetransTimer variable SHOULD be copied from the Retrans Timer
field, if the received value is non-zero.

These are wrappers around getpwuid_r() and friends, and will allocate the
right-sized buffer for this call.
We so far had multiple implementations of a buffer allocation loop
around getpwuid_r() and friends, and they all suck in some way. Let's
clean this up and add a common implementation, and use it everywhere.
Also, be more careful with error numbers, in particular systematically
turn ENOENT into ENOSRCH (the former is what is returned if /etc/passwd
is absent, which we want to consider identical to user not existing,
which is ENOSRCH). We so far did this at some invocations, but not all.
There are some invocations of getpwuid() left in the codebase. We really
should fix those too, and have a single unified implementation of the
logic, but those are not as trivial to convert, so left for another
time.
Let's grey the text out, and prefix it with a vertical grey bar, to make
clear this is output from the host, not the payload, and make it clearly
distinguishable from what follows.
Let's also make the image name clickable (with new enough
shared-mime-info this should allow you to look into the image with
gnome-disk-utility or a similar tool.
We cannot format the memory string via printf() %f format strings, since
that's locale dependent and qemu doesn't like that. hence format this as
an integer. We'll lose sub-MiB accuracy, but systems with less than 1
MiB memory don't really make much sense anyway.
Let's make the firmware file to choose configurable, and enumeratable.
This adds --firmware= to select the formare, and in particular
--firmware=list to show available options.
We already support -j as shortcut for JSON mode in various tools. Let's
add one more. We probably should add this systematically (at least where
it doesn't conflict with an existing -j switch with other purpose). But
I am too lazy to add that now.
There's some appetite to have the full os-release/machine-info data
exposed by hostnamed.
let's do so in the Describe() method and via Varlink. It's trivial after
all.

Without this I qemu simply froze in a weird state for me if I kill it:
it was supposedly a zombie, but we'd get the pidfd POLLIN event for it
only once the fd is closed. Hence let's close it right-away.
(Smells like a kernel issue actually, but too lazy to bother with this).
authselect 1.5.0 removed the "minimal" profile and added the "local"
profile instead. Let's modify our post-installation script to take
these changes into account.
Previously, path units would remain in the running state while their
target unit is deactivating. This left a window of time where the target
unit is no longer operational (i.e. it is busy deactivating/cleaning
up/etc) but the path unit would continue to ignore inotify events. In
short: any inotify event that occurs while the target unit deactivates
would be completely lost.
With this commit, the path will go back into a waiting state when the
target unit starts deactivating. This means that any inotify event that
occurs while the target unit deactivates will queue a start job.
