Zbigniew Jędrzejewski-Szmek 39dbd0c74c networkd: take ref immediately after storing item in set 
I'm not sure if I understand the code correctly, but it seems that if
storig in the second set failed, we'd return with the first set having
no reference on the link object, and the link object could be freed in the
future, leaving the set with a dangling reference.

Zbigniew Jędrzejewski-Szmek de7fef4b6e tree-wide: use set_ensure_put() 
Patch contains a coccinelle script, but it only works in some cases. Many
parts were converted by hand.

Note: I did not fix errors in return value handing. This will be done separate
to keep the patch comprehensible. No functional change is intended in this
patch.

Lennart Poettering 2a71d57f4e network: clean-up DHCP lease server data configuration 
This is an attempt to clean up the POP3/SMTP/LPR/… DHCP lease server
data logic in networkd. This reduces code duplication and fixes a number
of bugs.

This removes any support for collecting POP3/SMPT/LPR servers acquired
via local DHCP client releases since noone uses that, and given how old
these protocols are I doubt this will change. It keeps support for
configuring them for the dhcp server however.

The differences between the DNS/NTP/SIP/POP3/SMTP/LPR configuration
logics are minimized.

This removes the relevant symbols from sd-network.h (which is an
internal API only at this point after all).

This is unfortunately not well test, given the old code for this had
barely any tests. But the new code should not perform worse at least,
and allow us to release, since it corrects some interfaces visible in
the .network configuration format.

Fixes: #15943

Yu Watanabe c643bda5ec network: read driver name from ethtool 
To make Driver= in [Match] section work in containers.

Note that ID_NET_DRIVER= property in udev database is set with the
result of the ethtool. So, this should not change anything for
non-container cases.

Closes #15678.

Lennart Poettering ddb82ec2a2 sd-dhcp: clean-up of DHCP lease server code 
This is an attempt to clean-up the DHCP lease server type code a bit. We
now strictly use the same enum everywhere, and store server info in an
array. Moreover, we use the same nomenclature everywhere.

This only makes the changes in the sd-dhcp code. The networkd code is
untouched so far (but should be fixed up like this too. But it's more
complicated since this would then touch actual settings in .network
files).

Note that this also changes some field names in serialized lease files.
But given that these field names have not been part of a released
version of systemd yet, such a change should be ok.

This is pure renaming/refactoring, shouldn't actually change any
behaviour.

Zbigniew Jędrzejewski-Szmek ab76be5581 networkd: use SIGUSR2 to do a restart 
The code supports SIGTERM and SIGINT to termiante the process. It would
be possible to reporpose one of those signals for the restart operation,
but I think it's better to use a completely different signal to avoid
misunderstandings.
