In my plan, lsfd will need the information of the backing device for
"nsfs" file system before collecing the information about th namespaces
associated with fds.

scripts uses either a free-standing "file" argument, or the value
passed as --log-out "file". Additional filenames are ignored.
They are also ignored if --log-in "file" is given, as it turns off
output logging by default (can still be overriden by adding --log-out).
Avoid surprises when passing multiple filenames by writing usage
message instead.

crashes and make it possible for OSS-Fuzz to catch issues like
https://github.com/util-linux/util-linux/pull/1906.
With this patch applied the libblkid fuzz target built with the OSS-Fuzz
toolchain triggers "runtime error: load of misaligned address" in `probe_exfat`
so it seems to be working.

libblkid: iso9660: allocate enough space for UTF16 decoding
When merge_utf16be_ascii() encounters high-codepoint surrogate pairs it
emits four bytes of output for one byte of ascii input.
In addition with the remaining ascii characters from the second loop we
need up to 5 * sizeof(input) / 2 bytes as output buffer.
As we decode up to 128 ascii characters with merge_utf16be_ascii() we
need 320 bytes of buffer available.
Furthermore adapt merge_utf16be_ascii() to not write paste the output
buffer end.

pylibmount: properly mark initialization function
The module initialization function is supposed to only public function
in a module.
Newer versions of meson use -fvisibility=hidden and expected this
function to be marked with PyMODINIT_FUNC [0].
As this does not hurt on autotools either, let's use it everywhere.
This works around warnings about unused parameters.
To be correct we should be checking for the setns syscall, but so far we
don't have logic for this in meson.

libblkid: new fuzz target
* Added new fuzz target calling blkid_do_safeprobe(), mainly based off of how libblkid is used in the cryptsetup project (same flags used etc.)
* Added the fuzz target to the Makemodule and all relevant scripts.
* Made as part of my upcoming bachelor thesis.
This breaks the ABI interface. Cryptsetup reencrypt code
depends on checking the minimal accessible FS block
to prevent the destruction of the filesystem if a user
requests reencryption to a larger sector than
the filesystem can handle.
This patch removes the condition to make ABI compatible
again (as we cannot add FSINFO bit retrospectively).

logger: always update header when read from stdin
The current code updates the header only when the priority has been
changed. It's incorrect because wanted is a valid header or each entry
(don't forget that logger for stdin use-case is used in pipe to log
long-time running processes).
This patch also fixes the initial timestamp; it was originally generated
on logger startup, it now generates the header on the first message.
