This commit enables the microphone mute button and the screen rotate button, even if the latter is improperly linked. I have documented how to achieve this in https://wiki.archlinux.org/index.php/MSI_P15#Fn_Keys .
The call would always fail with:
systemd-userwork[780]: Failed to dlopen(libnss_systemd.so.2), ignoring: /usr/lib64libnss_systemd.so.2: cannot open shared object file: No such file or directory
For some reason the wait-online is failing intermittently; it's unclear
exactly why, but this hopefully avoids the failure for unrelated PR.
This is a workaround (not fix) for #16105
Several recent failed runs show that the test is still racy in two ways:
1) Sometimes it takes a while before the PID file is created, leading
to:
```
[ 10.950540] testsuite-47.sh[308]: ++ cat /leakedtestpid
[ 10.959712] testsuite-47.sh[308]: cat: /leakedtestpid: No such file or directory
[ 10.959824] testsuite-47.sh[298]: + leaked_pid=
```
2) Again, sometimes we check the leaked PID before the unit is actually
stopped, leading to a false negative:
```
[ 18.099599] testsuite-47.sh[346]: ++ cat /leakedtestpid
[ 18.116462] testsuite-47.sh[333]: + leaked_pid=342
[ 18.117101] testsuite-47.sh[333]: + systemctl stop testsuite-47-repro
...
[ 20.033907] testsuite-47.sh[333]: + ps -p 342
[ 20.080050] testsuite-47.sh[351]: PID TTY TIME CMD
[ 20.080050] testsuite-47.sh[351]: 342 ? 00:00:00 sleep
[ 20.082040] testsuite-47.sh[333]: + exit 42
```
Add support for creating a MACVLAN interface in "source" mode by
specifying Mode=source in the [MACVLAN] section of a .netdev file.
A list of allowed MAC addresses for the corresponding MACVLAN can also
be specified with the SourceMACAddress= option of the [MACVLAN] section.
An example .netdev file:
[NetDev]
Name=macvlan0
Kind=macvlan
MACAddress=02:DE:AD:BE:EF:00
[MACVLAN]
Mode=source
SourceMACAddress=02:AB:AB:AB:AB:01 02:CD:CD:CD:CD:01
SourceMACAddress=02:EF:EF:EF:EF:01
The same keys can also be specified in [MACVTAP] for MACVTAP kinds of
interfaces, with the same semantics.
The desktop file specification allows entries like ";;;;;;", full of empty strings.
But looking at the actual list of supported keys [1], empty entries are meaningless
(unless we would allow e.g. the desktop name to be the empty string. But that doesn't
seem very useful either). So let's just simplify our life and skip any empty substrings
entirely.
This would also resolve the fuzzer case:
$ valgrind build/fuzz-xdg-desktop test/fuzz/fuzz-xdg-desktop/oss-fuzz-22812
test/fuzz/fuzz-xdg-desktop/oss-fuzz-22812... ok

The fuzzer test case has a giant line with ";;;;;;;;;;;..." which is turned into
a strv of empty strings. Unfortunately, when pushing each string, strv_push() needs
to walk the whole array, which leads to quadratic behaviour. So let's use
greedy_allocation here and also keep location in the string to avoid iterating.

Fixes https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=22812.
Other minor changes:
- say "was already defined" instead of "defined multiple times" to make it
clear that we're ignoring this second definition, and not all definitions
of the key
- unescaping needs to be done also for the last entry
