The status string is modeled after our --version output: +enabled -disabled equals=more-info
For example:
Protocols: -DefaultRoute +LLMNR -mDNS -DNSOverTLS DNSSEC=allow-downgrade/supported
We would print the whole string as a single super-long line. Let's nicely
break the text into lines that fit on the screen.

By making them unsigned comparing them with other sizes is less likely
to trigger compiler warnings regarding signed/unsigned comparisons.
After all sizes (i.e. size_t) are generally assumed to be unsigned, so
these should be too.

There was some confusion about what POSIX says about variable names:
names shall not contain the character '='. For values to be portable
across systems conforming to POSIX.1-2008, the value shall be composed
of characters from the portable character set (except NUL and as
indicated below).
i.e. it allows almost all ASCII in variable names (without NUL and DEL and
'='). OTOH, it says that *utilities* use a smaller set of characters:
Environment variable names used by the utilities in the Shell and
Utilities volume of POSIX.1-2008 consist solely of uppercase letters,
digits, and the <underscore> ( '_' ) from the characters defined in
Portable Character Set and do not begin with a digit.
When enforcing variable names in environment blocks, we need to use this
first definition, so that we can propagate all valid variables.
I think having non-printable characters in variable names is too much, so
I took out the whitespace stuff from the first definition.
OTOH, when we use *shell syntax*, for example doing variable expansion,
it seems enough to support expansion of variables that the shell would allow.
Fixes#14878,

Latest glibc has deprecated mallinfo(), so it might become unavailable at some point
in the future. There is malloc_info(), but it returns XML, ffs. I think the information
that we get from mallinfo() is quite useful, so let's use mallinfo() if available, and
not otherwise.
This helper alone doesn't make too much sense, but it's preparatory work
for #17274, and I guess it can't hurt to land it early, it does make the
ratelimit code a tiny bit prettier after all.
Currently systemd-detect-virt fails to detect running under PowerVM.
Add code to detect PowerVM based on code in util-linux.

THis doesn't change the condition's logic at all, but is an attempt to
make things a bit more readable: instead of checking log_target !=
LOG_TARGET_AUTO let's actually list the targets where we want to
consider journal/syslog/kmsg, to make things a bit less confusing. After
all the message here is not to avoid them if LOG_TARGET_AUTO is set, but
to definitely do them in the other cases.
It always was the intention to expose this as trusted field _TID=, i.e.
automatically determine it from journald via some SCM_xyz field or so,
but this is never happened, and it's unlikely this will be added anytime
soon to the kernel either, hence let's just generate this sender side,
even if it means it's untrusted.
