5800f0fc68 basic/alloc-util: also reset the cleaned-up variable in freep()
freep() has it's own definition, so I missed it in fd421c4adc.

Again, there is a small growth, but the compiler should be able to optimize it away:

36290e0b97 xdg-autostart-generator: ignore DBusActivatable=true
See https://wiki.gnome.org/HowDoI/DBusApplicationLaunching and
https://wiki.gnome.org/Initiatives/GnomeGoals/DBusActivatable for a description
of this key:
> Instead of the typical UNIX-style fork()/exec() approach to process creation,
> launching an application is done by sending a D-Bus message to the well-known
> name of that application, causing a D-Bus activation.
>
> Starting processes with D-Bus activation ensures that each application gets
> started in its own pristine environment, as a direct descendent of the
> session -- not in the environment of whatever its parent happened to be. This
> is important for ensuring the app ends up in the correct cgroup, for example.

So this motivation is not important for us: we launch stuff ourselves better.

This fixes warnings during boot:
systemd-xdg-autostart-generator[2274]: /etc/xdg/autostart/org.freedesktop.problems.applet.desktop:92: Unknown key name 'DBusActivatable' in section 'Desktop Entry', ignoring.

4c72d851cd network: warn when any positive boolean string is specified for IPMasquerade=
Previously, any positive boolean string for IPMasquerade= enables only IPv4
masquerade. The commit 48ed276647 adds
IPv6 masquerade support. However, only "yes" is handled as "ipv4", and other
positive boolean strings are handled as "both".

This makes all positive boolean strings considered as "ipv4", warn that they
are deprecated, and suggest to use "ipv4" or "both".

Follow-up for 48ed276647.

d06e7fb532 oomd: increase accuracy of SwapUsedLimit= to permyriads too
oomd.conf has two parameters with fractionals: SwapUsedLimit= and
DefaultMemoryPressureLimit=, but one accepts permyriads, the other only
percentages, for no apparent reason. One carries the "Percent" in the
name, the other doesn't.

Let's clean this up: always accept permyriads, and drop the suffix,
given that it is misleading.

I figure we should internally try to focus on scaling everything
relative to UINT32_MAX, and if that isn't in the cards at least 10000,
but never permille nor percent unless there's a really really good
reason for it (e.g. interface defined by someone else).

d9d3f05def core: use our usual UINT32_MAX scaling for OOMD limits
So far OOMD limits used permyriads, as an upgrade from the original
percent.

The rest of our codebase typically scales stuff relative to UINT32_MAX.
Let's clean this up, an make sure this happens here too. This is
particularly relevant, as this is exposed in unit files and API, and
before we mark this stable we should get the APIs right.

1ead0b2a79 parse-util: add format string macro for outputting permyriad
Let's define a set of macros for making output of permyriad values easy.
They are printed in pure ASCII, i.e. without the permille/permyriad
suffix, using just percent and two places after the dot.

3b6e71ad03 util: add some helpers for converting percent/permille/permyriad to parts of 2^32-1
At various places we accept values scaled to the range 0…2^32-1 which
are exposed to the user as percentages/permille/permyriad. Let's add
some helper macros (actually: typesafe macro-like functions) that help
with converting our internal encoding to the external encodings.

benefits: some of the previous code rounded up, some down. let's always
round to nearest, to ensure that our conversions are reversible. Also,
check for overflows correctly.

This also adds a test that makes sure that for the full
percent/permille/permyriad ranges we can convert forth and back without
loss of accuracy.

38d0c27006 percent-util: when parsing permyriads, permit percents too with 1 place after the dot
Previously, when parsing myriads, we'd support:

 x%          → percent, no places after the dot
 x.yz%       → percent, two places after the dot
 x‰          → permille, no places after the dot
 x.y‰        → permille, one place after the dot
 x‱          → permyriad, no places after the dot

What's missing is:

 x.y%        → percent, one place after the dot

Let's add it in.

ed5033fd6c util: move percent/permille/permyriad parser into percent-util.[ch]

ff03bfa508 udevadm: after validating action, use our internal string instead of optarg
This doesn't really change anything, but feels nicer, since it abstracts
away what device_action_from_string()/device_action_to_string() do
internally, and always uses a normalized action string (yes, there's no
ambiguity, but it's nice to stay abstract, maybe one day there is
ambiguity around this)

a113002214 sd-device: add sd_device_get_action() + sd_device_get_seqnum() + sd_device_new_from_stat_rdev()
To make sd-device properly usable for all programs we need to provide an
API for the "action" field of an event, it's one of the most relevant
ones, and it was so far missing.

This also adds sd_device_get_seqnum(), which isn't that interesting,
except for generating pretty debug output, which we use it ourselves
for.

This also makes device_new_from_stat_rdev() public, as it is truly
useful, as we can see in our own uses of it, and I think is fairly
generic to show up in the public APIs.
