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.

e4de72876e util-lib: split out all temporary file related calls into tmpfiles-util.c 
This splits out a bunch of functions from fileio.c that have to do with
temporary files. Simply to make the header files a bit shorter, and to
group things more nicely.

No code changes, just some rearranging of source files.

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:

baaa35ad70 coccinelle: make use of SYNTHETIC_ERRNO 
Ideally, coccinelle would strip unnecessary braces too. But I do not see any
option in coccinelle for this, so instead, I edited the patch text using
search&replace to remove the braces. Unfortunately this is not fully automatic,
in particular it didn't deal well with if-else-if-else blocks and ifdefs, so
there is an increased likelikehood be some bugs in such spots.

I also removed part of the patch that coccinelle generated for udev, where we
returns -1 for failure. This should be fixed independently.

fde32028a4 Move LONG_LINE_MAX definition to fileio.h 
All users of the macro (except for one, in serialize.c), use the macro in
connection with read_line(), so they must include fileio.h.  Let's not play
libc games and require multiple header file to be included for the most common
use of a function.

The removal of def.h includes is not exact. I mostly went over the commits that
switch over to use read_line() and add def.h at the same time and reverted the
addition of def.h in those files.
