026c2677fc macro: add macro for llvm no_sanitize_address attribute 
We want it for global variables, which LLVM supports and GCC currently
does not (GCC does support it for functions, but we care about global
variables here).

Why is this relevant? When asan is used global variables are padded with
hotzones before and after. But we can't have that for the registration
variables we place in special ELF sections: we want them tightly packed
so that we can iterate through them.

Note that for gcc this isn't an issue, as it will pack stuff in
non-standard sections anyway, even if asan is used.

a898603563 sd-bus,static-destruct: clean up how we do our ELF section magic 
This cleans up a bit how we set up things for the ELF section magic:

1. Let's always use our gcc macros, instead of __attribute__ directly

2. Align our structures to sizeof(void*), i.e. the pointer size, rather
   than a fixed 8 or __BIGGEST_ALIGNMENT__. The former is unnecessarily
   high for 32bit systems, the latter too high for 64bit systems. gcc
   seems to use ptr alignment for static variables itself, hence this
   should be good enough for us too. Moreover, the Linux kernel also
   uses pointer alginment for all its ELF section registration magic,
   hence this should be good enough for us too.

3. Let's always prefix the sections we create ourself with SYSTEMD_,
   just to make clear where they come from.

4. Always align the pointer we start from when iterating through these
   lists. This should be unnecessary, but makes things nicely
   systematic, as we'll align all pointers we use to access these
   sections properly.

2ee1c55d6c tree-wide: drop redundant space between __attribute__ and (( 
We follow no general rule, but in most cases we do not place a space
outside of macro.h. Hence let's stick to that, and adapt macro.h too,
and follow the rule systematically that there shall not be a space
between __attribute__ and ((...

Yes, this does not matter at all, and is purely OCD cosmetics. But then
again, the uses of __attribute__ are very local only, hence the changes
cleaning this up are small and are unlikely to have to be repeated too
often...

15dca3711d basic/socket-util: use c-escaping to print unprintable socket paths 
We are pretty careful to reject abstract sockets that are too long to fit in
the address structure as a NUL-terminated string. And since we parse sockets as
strings, it is not possible to embed a NUL in the the address either.  But we
might receive an external socket (abstract or not), and we want to be able to
print its address in all cases. We would call socket_address_verify() and
refuse to print various sockets that the kernel considers legit.

Let's do the strict verification only in case of socket addresses we parse and
open ourselves, and do less strict verification when printing addresses of
existing sockets, and use c-escaping to print embedded NULs and such.

More tests are added.

This should make LGTM happier because on FIXME comment is removed.

b06f0cc625 parse-util: allow parse_boolean() to take a NULL argument 
It's pretty useful to allow parse_boolean() to take a NULL argument and
return an error in that case, rather than abort. i.e. making this a
runtime rather than programming error allows us to shorten code
elsewhere.

049af8ad0c Split out part of mount-util.c into mountpoint-util.c 
The idea is that anything which is related to actually manipulating mounts is
in mount-util.c, but functions for mountpoint introspection are moved to the
new file. Anything which requires libmount must be in mount-util.c.

This was supposed to be a preparation for further changes, with no functional
difference, but it results in a significant change in linkage:
