Zbigniew Jędrzejewski-Szmek b45c068dd8 basic/env-util: (mostly) follow POSIX for what variable names are allowed 
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.

Zbigniew Jędrzejewski-Szmek 4b6f74f5a0 basic/selinux: work around mallinfo deprecation 
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.

Lennart Poettering 2a155c53ab ratelimit: add ratelimit_configured() helper 
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.

Lennart Poettering ef9bddb799 log: normalize log target condition check 
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.

Lennart Poettering 38ffc7d18a log: include TID= field in structred log output 
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.
