Rework cmdline printing to use unicode
The functions to retrieve and print process cmdlines were based on the
assumption that they contain printable ASCII, and everything else
should be filtered out. That assumption doesn't hold in today's world,
where people are free to use unicode everywhere.
This replaces the custom cmdline reading code with a more generic approach
using utf8_escape_non_printable_full().
For kernel threads, truncation is done on the parenthesized name, so we'll
get "[worker]", "[worker…]", …, "[w…]", "[…", "…" as we reduce the number of
available columns.
This implementation is most likely slower for very long cmdlines, but I don't
think this is very important. The common case is to have short commandlines,
and should print those properly. Absurdly long cmdlines are the exception,
which needs to be handled correctly and safely, but speed is not too important.
Fixes #12532.
v2:
- use size_t for the number of columns. This change propagates into various
other functions that call get_process_cmdline(), increasing the size of the
patch, but the changes are rather trivial.

try.
List existing images:

1 images

$> systemd-nspawn -M Fedora-Cloud-Base-30-1.2.x86_64.raw
No image for machine 'Fedora-Cloud-Base-30-1.2.x86_64.raw'.
Removing the ".raw" extension launches the image and gives a shell.
Update the man page to reflect that.
Frantisek Sumsal on #systemd (Freenode) noted the reason: "In older
versions systemd -M accepted both image-name.raw and image-name as a
valid image names, however, on Fedora 29 (systemd-239) with all the

extension)"

test: search $BOOT for kernel+initrd
$BOOT is the preferred location for kernel images. If $BOOT does not
exist, -x will print the path to ESP, so well fall back to previous
behaviour.

bootctl: do not allow -x and -p to be used together
-x already prints the path to ESP in some circumstances, and allowing
both to be printed seems confusing.

bootctl: add -x shortcut for --print-boot-path
It's a quite useful option, let's match -p.
