14bf2c9d37 util: allow trailing semicolons on define_trivial_cleanup_func lines
Emacs C indenting really gets confused by these lines if they carry no
trailing semicolon, hence let's make this nicer for good old emacs. The
other macros which define functions already do this too, so let's copy
the scheme here.

Also, let's use an uppercase name for the macro. So far our rough rule
was that macros that are totally not function-like (like this ones,
which define a function) are uppercase. (Well, admittedly it is a rough
rule only, for example function and variable decorators are all
lower-case SINCE THE CONSTANT YELLING IN THE SOURCES WOULD SUCK, and
also they at least got underscore prefixes.) Also, the macros that
define functions that we already have are all uppercase, so let's do the
same here...

b92bea5d2a Use initalization instead of explicit zeroing
Before, we would initialize many fields twice: first
by filling the structure with zeros, and then a second
time with the real values. We can let the compiler do
the job for us, avoiding one copy.

A downside of this patch is that text gets slightly
bigger. This is because all zero() calls are effectively
inlined:

$ size build/.libs/systemd
         text    data     bss     dec     hex filename
before 897737  107300    2560 1007597   f5fed build/.libs/systemd
after  897873  107300    2560 1007733   f6075 build/.libs/systemd

… actually less than 1‰.

A few asserts that the parameter is not null had to be removed. I
don't think this changes much, because first, it is quite unlikely
for the assert to fail, and second, an immediate SEGV is almost as
good as an assert.

7f602784de util: rename parse_usec() to parse_sec() sinds the default unit is seconds
Internally we store all time values in usec_t, however parse_usec()
actually was used mostly to parse values in seconds (unless explicit
units were specified to define a different unit). Hence, be clear about
this and name the function about what we pass into it, not what we get
out of it.

fabe5c0e5f binfmt,tmpfiles,modules-load,sysctl: rework the various early-boot services that work on .d/ directories
This unifies much of the logic behind them:

- All four will now ofllow the rule that the earlier file and earlier
  assignment in the .d/ directories wins. Before, sysctl was the only
  outlier, where the later setting always won.

- All four now support getopt() and --help on the command line.

- All four can now handle specification of configuration file names on
  the command line to apply. The tools will automatically find them, and
  apply them. Previously only tmpfiles could do that. This is useful for
  %post scripts in RPMs and suchlike.

- This fixes various error path issues in conf_files_list()

78a92a5a23 tmpfiles: introduce type X
Type X will exclude path itself from clean-up. However, if the path is a
directory systemd-tmpfiles will clean-up its content.

In contrast to type x, where path is ignored completely, type X needs some
Age parameter. In order to determine Age parameter, we will look for config
entries of type d or D and pick the best match.  Best match is either
exact match or longest prefix match.

a2558205f7 tmpfiles: allow Age to be set to 0
Mostly useful for testing purposes. Setting Age to 1s works just as
well, but it is surprising that using 0s (or just 0) does not work.

54693d9bfa tmpfiles: use write(2) for the 'w' action
This resolves problems with filesystems which do not implement the
aio_write file operation. In this case, the kernel will fall back using
a loop writing technique for each pointer in a received iovec. The
result is strange errors in dmesg such as:

[   31.855871] elevator: type  not found
[   31.856262] elevator: switch to
[   31.856262]  failed

It does not make sense to implement a synchronous aio_write method for
sysfs as this isn't a real filesystem where a reasonable use case for
using writev exists, nor is there an expectation that tmpfiles will be
used to write more data than can be reasonably written in a single write
syscall.

In addition, some sysfs attrs are currently buggy and will NOT reject
the second write with the newline, causing the sysfs value to be zeroed
out. This of course should be fixed in the kernel regardless of any
wrongdoing in userspace, but this simple change makes us immune to such
a bug.

This change means that we do not write a trailing newline by default, as
the expected use case of 'w' is for sysfs and procfs. In exchange, honor
C-style backslash escapes so that if the newline is really needed, the
user can add it.

d4e9eb91ea tmpfiles: support globbing for w option
Break out the write logic into a separate function and simply use it as
a callback to glob_item.

This allows users to consolidate writes to sysfs with multiple similar
pathnames, e.g.

  w /sys/class/block/sd[a-z]/queue/read_ahead_kb - - - - 1024

https://bugs.freedesktop.org/show_bug.cgi?id=38686

I don't think the usecase case in that bug makes much sense, but all the
other tools do honour /lib in the search path so we probably should do
that here, too.
