In the light of #12926 I needed some log messages for testing. This
tmpfiles one came to mind, since it's frequently seen on typical Fedora
systems. Alas, they didn't actually use log_syntax, and thus weren't
recognizable by the new config file urlifaction code. Let's fix that.
This means the the code needs to be kept compatible in the shared header,
but I think that still nicer than having two places to declare the same
things.
I added src/boot to -I, so that efi/foo.h needs to be used. This reduces
the potential for accidentally including the wrong header.
Now all short-*, verbose, with-unit modes are handled. cat, export, json-* are
not, but those are usually used for post-processing, so I don't think it'd be
useful there.
Fixes#12931.

cc1: some warnings being treated as errors
With gcc-9.1.1-2.fc31.x86_64 and -Doptimization=2:
../src/shared/dm-util.c: In function ‘dm_deferred_remove’:
../src/shared/dm-util.c:35:9: warning: ‘strncpy’ specified bound 128 equals destination size [-Wstringop-truncation]
35 | strncpy(dm.name, name, sizeof(dm.name));
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
gcc is plain wrong here, because we checked strlen(name) a few lines above, so
there can be no truncation and even the terminator always fits. But let's avoid
the warning.
Make use of curl_multi_assign to associate each IO sd_event_source with
a CURL object. This means we always get passed the right event source
and don't need to worry about looking up the associated CURL object,
particularly in the case where the FD has been closed on a REMOVE event.
In Ubuntu CI, udev-test.pl is run from the debian/test/udev script,
in a test dir created for it; but udev-test.pl setup mounts a
dir, so if it doesn't cleanup/unmount before exiting, the test dir
autopkgtest created for it can't be removed, and autopkgtest
aborts the entire test suite, for example this output (from a
test run inside an armhf container):
autopkgtest [12:45:36]: test udev: [-----------------------

Fixes#12258.
This is enough to reproduce:
$ systemd-run bash -c 'sleep 10' && systemctl daemon-reload
would result in
Current command vanished from the unit file.
We would serialize as:
ExecStart 0 /usr/bin/bash /usr/bin/bash -c sleep 10000
which of course can't work.
Now we serialize as
ExecStart 0 /usr/bin/bash "/usr/bin/bash" "-c" "sleep 10".
If execve failed, we would die in safe_close(), because master was already
closed by fdset_close_others() on line 3123. IIUC, we don't need to keep the
fd open after sending it, so let's just close it immediately.
Reproducer:
sudo build/systemd-nspawn -M rawhide fooooooo
Fixup for 3acc84ebd9.
The `set -e` option is incompatible with a subshell/compound command,
which is followed by || <EXPR>. In such case, the -e option is ignored
in all affected subshells/functions (see man bash(1) for command `set`).
In certain cases we might attempt to install a binary which is already
present in the test image, yet it's missing from the host system.
In such cases, let's check if the binary indeed exists in the image
before doing any other chcecks. If it does, immediately return with
success.
This was discovered during installation of
/usr/lib/systemd/systemd-bless-boot, which was not present in Ubuntu CI
(as the installed systemd was from the Ubuntu repositories), and the
binary itself was already in the image thanks to `ninja install`.
However, during extraction of binaries from the systemd service files,
another attempt to install this binary was made, which failed due to
`find_binary` being unable to find it.
We use that on all other services, and hence should here too. Otherwise
the service will be killed with SIGSYS when doing something not
whitelisted, which is a bit crass.
