build-sys: bring back an intltool-update workaround
Currently, 'make distcheck' fails with an error such as this:
srcdir=../../po /usr/bin/intltool-update -m
The following files contain translations and are currently not in use.
Please consider adding these to the POTFILES.in file, located in the po/ directory.
This is caused by a new behavior of autmake 1.15 which changed the
location of the build tree during 'make distcheck', and the fact that
intltool doesn't yet ignore that paths.
We used to have a workaround in configure.ac that makes the failing call
a no-op, but it was accidentially removed in 23756070
("remove gudev and gtk-doc").
Bring back that snipet for now, until intltool and automake sorted out
their issues and like each other again.

man: revert dynamic paths for split-usr setups
This did not really work out as we had hoped. Trying to do this upstream
introduced several problems that probably makes it better suited as a
downstream patch after all. At any rate, it is not releaseable in the
current state, so we at least need to revert this before the release.
* by adjusting the path to binaries, but not do the same thing to the
search path we end up with inconsistent man-pages. Adjusting the search
path too would be quite messy, and it is not at all obvious that this is
worth the effort, but at any rate it would have to be done before we
could ship this.
* this means that distributed man-pages does not make sense as they depend
on config options, and for better or worse we are still distributing
man pages, so that is something that definitely needs sorting out before
we could ship with this patch.
* we have long held that split-usr is only minimally supported in order
to boot, and something we hope will eventually go away. So before we start
adding even more magic/effort in order to make this work nicely, we should
probably question if it makes sense at all.
nspawn: suppress warning when /etc/resolv.conf is a valid symlink
In such a case let's suppress the warning (downgrade to LOG_DEBUG),
under the assumption that the user has no config file to update in its
place, but a symlink that points to something like resolved's
automatically managed resolve.conf file.
While we are at it, also stop complaining if we cannot write /etc/resolv.conf
due to a read-only disk, given that there's little we could do about it.

test: disable test-barrier by default
The test-barrier binary uses real-time alarms and timeouts to test for
races in the thread-barrier implementation. Hence, if your system is under
high load and your scheduler decides to not run test-barrier for
>BASE_TIME, then the tests are likely to fail.
Two options:
1) Increase BASE_TIME. This will make the test take significantly longer
for no real good. Furthermore, it is still not guaranteed that the
task is scheduled.
2) Don't rely on real-time timers, but use explicit synchronization. This
would basically test one barrier implementation with another.. kinda
ironic.. but maybe something worth looking into.
3) Disable test-barrier by default.
This patch chooses option 3) and makes sure test-barrier only runs if you
pass any argument.
Side note:
test-barrier is written in a way that if it fails under load, but
does not on idle systems, then it is very _unlikely_ that the
barrier implementation is the culprit. Hence, it makes little
sense to run it under load, anyway. It will not improve the test
coverage of barrier.c, but rather the coverage of the test itself.

journal: make sure the clock increases strict monotonic
Let's work around crappy clocks in test-journal-interleaving.c too. This

load-fragment: reset the list on an ExecStart= containing only whitespace
This is consistent with how an empty string works in an ExecStart=
statement. We should not differentiate between an empty string and
whitespace only (since they look the same.)
Update the test case with whitespace only to reflect that the list is
reset.
Tested that `test-unit-file` passes and other test cases are not
affected. Installed the patched systemd binaries on a machine, booted
it, looked for out of the usual behavior but did not find any.
load-fragment: use unquote_first_word in config_parse_exec
Convert config_parse_exec() from using FOREACH_WORD_QUOTED into a loop
of unquote_first_word.
Loop through the arguments only once (the FOREACH_WORD_QUOTED
implementation did it twice, once to count them and another time to
process and store them.)
Use newly introduced flag UNQUOTE_UNESCAPE_RELAX to preserve
unrecognized escape sequences such as regexps matches such as "\w",
"\d", etc. (Valid escape sequences such as "\s" or "\b" still need an
extra backslash if literals are desired for regexps.)
Differences in behavior:
- Handle ; (command separator) in special, so that only ; on its own is
valid for that purpose, an quoted semicolon ";" or ';' will now behave
as a literal semicolon. This is probably what was initially intended.
- Handle \; (to introduce a literal semicolon) in special, so that only \;
is turned into a semicolon but not \\; or "\\;" or "\;" which are kept
as a literal \; in the output. This is probably what was initially
intended.
Known issues:
- Using an empty string (for example, ExecStartPre=<empty>) will empty
the list and remove the existing commands, but using whitespace only
(for example, ExecStartPre=<spaces>) will not. This is a pre-existing
issue and will be dealt with in a follow up commit.
Tested:
- Unit tests passing. Also `make distcheck` still works as expected.
- Installed it on a local machine and booted with it, checked console
output, systemctl and journalctl output, did not notice any issues
running the patched systemd binaries.
These tests will be useful to check the cases regarding quoted and
escaped semicolon when we switch to using unquote_first_word.
Additionally, convert some of the tests that have semicolons so that the
argument after the semicolon looks like a path (starts with /) so that
we can see the change of behavior when making config_parse_exec more
strict about what it accepts as a command separator.
It will try to unquot_first_word, but if it runs into escaping problems
it will retry it adding UNQUOTE_CUNESCAPE_RELAX to the flags. If it
succeeds on the second try, it will log a warning about it. If it fails
both times, it will log an error.
util: New flag UNQUOTE_UNESCAPE_RELAX for unquote_first_word
The new flag UNQUOTE_UNESCAPE_RELAX preserves unrecognized escape
sequences verbatim in unquote_first_word, either when it's a trailing
backslash (similar to UNQUOTE_RELAX, but in this case keep the extra
backslash in the output) or in the middle of a sequence string.
Add unit test cases to ensure the new flag works as expected and to
prevent regressions from being introduced.
Tested with a follow up commit converting config_parse_exec() to start
using unquote_first_word, in which case this flags makes it possible to
preserve unrecognized escape sequences.

bus: fix installing DRIVER matches on kdbus
In kdbus we still have to support org.freedesktop.DBus matches even though
there is no real bus driver. The reason is that bus-control.c turns
NameOwnerChanged matches into proper kdbus matches. If we drop DRIVER
matches early, we will never match on name-changes for kdbus.
Two ways to fix this:
1) Install DRIVER matches on kdbus (which is the simple way our and which
is what this patch does).
2) Properly fix the scope-detection to let NameOwnerChanged matches
through (or better: block anything with Member!=NameOwnerChanged).
Not all watchdog drivers implement WDIOC_SETOPTIONS. Drivers which do
not implement it have their device always enabled. So it's fine to
report an error if WDIOS_DISABLECARD is passed and the ioctl is not
implemented, however failing when WDIOS_ENABLECARD is passed and the
ioctl is not implemented is not good: if the device was already
enabled then WDIOS_ENABLECARD was a no-op and wasn't needed in the
first place. So we can just ignore the error and continue.

logind: save /run/systemd/users/UID before starting user@.service
Previously, this had a race condition during a user's first login.
Some component calls CreateSession (most likely by a PAM service
other than 'systemd-user' running pam_systemd), with the following
results:
- logind:
* create the user's XDG_RUNTIME_DIR
* tell pid 1 to create user-UID.slice
* tell pid 1 to start user@UID.service
Then these two processes race:
- logind:
* save information including XDG_RUNTIME_DIR to /run/systemd/users/UID
- the subprocess of pid 1 responsible for user@service:
* start a 'systemd-user' PAM session, which reads XDG_RUNTIME_DIR
and puts it in the environment
* run systemd --user, which requires XDG_RUNTIME_DIR in the
environment
If logind wins the race, which usually happens, everything is fine;
but if the subprocesses of pid 1 win the race, which can happen
under load, then systemd --user exits unsuccessfully.
To avoid this race, we have to write out /run/systemd/users/UID
even though the service has not "officially" started yet;
previously this did an early-return without saving anything.
Record its state as OPENING in this case.
