b45e4eb679 sd-ipv4ll: rework callbacks
Firstly, no longer distinguish between STOP and INIT states.

Secondly, do not trigger STOP events when calls to sd_ipv4ll_*() fail. The
caller is the one who would receive the event and will already know that the
call to sd_ipv4ll_*() has failed, so it is redundant.

STOP events will now only be triggered by calling sd_ipv4ll_stop() explicitly
or by some internal error in the library triggered by receiving a packet or
an expiring timeout (i.e., any error that would otherwise not be reported
back to the consumer of the library).

Lastly, follow CODING_STYLE and always return NULL on unref. Protect from
objects being destroyed in callbacks accordingly.

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.

75f86906c5 basic: rework virtualization detection API
Introduce a proper enum, and don't pass around string ids anymore. This
simplifies things quite a bit, and makes virtualization detection more
similar to architecture detection.

397d15fd39 networkd: adjust error codes for nonexisting DHCP data
Commit 0339cd770 changed libsystemd-network's error code for missing DHCP lease
data from ENOENT to ENODATA. Adjust networkd accordingly.

This fixes interfaces being stuck in "degraded/configuring" mode forever.

9b3a67c55b networkd: dhcp-server - allow configuration of the pool
The constraints we place on the pool is that it is a contiguous
sequence of addresses in the same subnet as the server address, not
including the subnet nor broadcast addresses, but possibly including
the server address itself. If the server address is included in the
pool it is (obviously) reserved and not handed out to clients.

9963469618 sd-dhcp-server: simplify pool creation
Merge sd_dhcp_server_set_address() and sd_dhcp_server_set_lease_pool() into
sd_dhcp_server_configure_pool() as the behavior of the two former depends
on the order they are called in. The flexibility is not needed, so let's
just do this in one call.

4b7b5abb78 dhcp: NTP servers should be requested by networkd but not implicitly by sd-dhcp
The library so far always requested the NTP servers. This might be
unnecessary in some uses, hence let's move the request into networkd
instead.

bd91b83e57 dhcp: keep lease save/load functions private
When we make sd-dhcp public one day we really should not make
sd_dhcp_lease_save() and sd_dhcp_lease_load() public, since it's pretty
much only useful as internal utility for networkd itself.

e6b18ffaea sd-dhcp: don't randomly ref objects
In our API design, getter-functions don't ref objects. Calls like
foo_get_bar() will not ref 'bar'. We never do that and there is no real
reason to do it in single threaded APIs. If you need a ref-count, you
better take it yourself *BEFORE* doing anything else on the parent object
(as this might invalidate your pointer).

Right now, sd_dhcp?_get_lease() refs the lease it returns. A lot of
code-paths in systemd do not expect this and thus leak the lease
reference. Fix this by changing the API to not ref returned objects.

Tests are modified to check behaviour with relax and without relax.
New tests are added for hostname_cleanup().
Tests are moved a new file (test-hostname-util) because there's
now a bunch of them.

New parameter is not used anywhere, except in tests, so there should
be no observable change.

27ec691bfd tree-wide: convert bootchart and lldp code to use clock_boottime_or_monotonic()
We should avoid using CLOCK_BOOTTIME directly unless we actually can
sensible distuingish it from CLOCK_MONOTONIC. CLOCK_BOOTTIME is only
fully feature on very recent Linux kernels, hence we should stick to a
fallback logic, which is already available in the
clock_boottime_or_monotonic() call.
