3f6fd1ba65 util: introduce common version() implementation and use it everywhere
This also allows us to drop build.h from a ton of files, hence do so.
Since we touched the #includes of those files, let's order them properly
according to CODING_STYLE.

76ef789d26 tree-wide: make use of log_error_errno() return value
Turns this:

        r = -errno;
        log_error_errno(errno, "foo");

into this:

        r = log_error_errno(errno, "foo");

and this:

        r = log_error_errno(errno, "foo");
        return r;

into this:

        return log_error_errno(errno, "foo");

a1e58e8ee1 tree-wide: use coccinelle to patch a lot of code to use mfree()
This replaces this:

        free(p);
        p = NULL;

by this:

        p = mfree(p);

Change generated using coccinelle. Semantic patch is added to the
sources.

3e044c492e Bug #944: Deletion of unnecessary checks before a few calls of systemd functions
The following functions return immediately if a null pointer was passed.
* calendar_spec_free
* link_address_free
* manager_free
* sd_bus_unref
* sd_journal_close
* udev_monitor_unref
* udev_unref

It is therefore not needed that a function caller repeats a corresponding check.

This issue was fixed by using the software Coccinelle 1.0.1.

8adaf7bd23 strv: convert strv_split_quotes into a generic strv_split_extract
strv_split_extract is to strv_split_quotes as extract_first_word was to
unquote_first_word.

Now there's extract_first_word for extracting a single argument,
extract_many_words for extracting a bounded number of arguments,
and strv_split_extract for extracting an arbitrary number of arguments.

dacd6cee76 tree-wide: port everything over to fflush_and_check()

72c0a2c255 everywhere: port everything to sigprocmask_many() and friends
This ports a lot of manual code over to sigprocmask_many() and friends.

Also, we now consistly check for sigprocmask() failures with
assert_se(), since the call cannot realistically fail unless there's a
programming error.

Also encloses a few sd_event_add_signal() calls with (void) when we
ignore the return values for it knowingly.

4034a06ddb util: rework word parsing and c unescaping code
When parsing words from input files, optionally automatically unescape
the passed strings, controllable via a new flags parameter.

Make use of this in tmpfiles, and port everything else over, too.

This improves parsing quite a bit, since we no longer have to process the
same string multiple times with different calls, where an earlier call
might corrupt the input for a later call.

043945b938 journal-remote: process events without delay
journal-remote buffers input, and then parses it handling one journal entry at a time.
It was possible for useful data to be left in the buffer after some entries were
processesed. But all data would be already read from the fd, so there would be
no reason for the event loop to call the handler again. After some new data came in,
the handler would be called again, and would then process the "old" data in the buffer.

Fix this by enabling a handler wherever we process input data and do not exhaust data
from the input buffer (i.e. when EAGAIN was not encountered). The handler runs until
we encounter EAGAIN.

Looping over the input data is done in this roundabout way to allow the event loop
to dispatch other events in the meanwhile. If the loop was inside the handler, a
source which produced data fast enough could completely monopolize the process.

5ffa8c8181 Add a snprinf wrapper which checks that the buffer was big enough
If we scale our buffer to be wide enough for the format string, we
should expect that the calculation was correct.

char_array_0() invocations are removed, since snprintf nul-terminates
the output in any case.

A similar wrapper is used for strftime calls, but only in timedatectl.c.

2cf4172a71 journal: install sigbus handler for journal tools too
This makes them robust regarding truncation. Ideally, we'd export this
as an API, but given how messy SIGBUS handling is, and the uncertain
ownership logic of signal handlers we should not do this (unless libc
one day invents a scheme how to sanely install SIGBUS handlers for
specific memory areas only). However, for now we can still make all our
own tools robust.

Note that external tools will only have read-access to the journal
anyway, where SIGBUS is much more unlikely, given that only writes are
subject to disk full problems.

56f64d9576 treewide: use log_*_errno whenever %m is in the format string
If the format string contains %m, clearly errno must have a meaningful
value, so we might as well use log_*_errno to have ERRNO= logged.

Using:
find . -name '*.[ch]' | xargs sed -r -i -e \
's/log_(debug|info|notice|warning|error|emergency)\((".*%m.*")/log_\1_errno(errno, \2/'

Plus some whitespace, linewrap, and indent adjustments.
