Yu Watanabe f1c22cf4da network: do not try to drop addresses or routes of unmanaged interfaces on carrier lost 
Currently, link_stop_engines(), link_drop_config(), and link_drop_foreign_config()
do nothing when the interface is unmanaged. So this does not change anything.
But returning earlier should be clear and safer for protecting configs
on unmanaged interfaces.

Yu Watanabe 7920d0a135 udev-node: drop redundant trial of devlink creation 
Previously, the devlink was created based on the priority saved in udev
database. So, we needed to reevaluate devlinks after database is saved.

But now the priority is stored in the symlink under /run/udev/links, and
the loop of devlink creation is controlled with the timestamp of the
directory. So, the double evaluation is not necessary anymore.

Yu Watanabe 0063fa23a1 udev-node: add random delay on conflict in updating device node symlink

Yu Watanabe 242d39ebc1 udev-node: always atomically create symlink to device node 
By the previous commit, it is not necessary to distinguish if the devlink
already exists. Also, I cannot find any significant advantages of the
previous complecated logic, that is, first try to create directly, and then
fallback to atomically creation. Moreover, such logic increases the chance
of conflicts between multiple udev workers.

This makes devlinks always created atomically. Hopefully, this reduces the
conflicts between the workers.

Yu Watanabe 8f27311eb2 udev-node: assume no new claim to a symlink if /run/udev/links is not updated 
During creating a symlink to a device node, if another device node which
requests the same symlink is added/removed, `stat_inode_unmodified()`
should always detects that. We do not need to continue the loop
unconditionally.

Yu Watanabe 377a83f0d8 udev-node: save information about device node and priority in symlink 
Previously, we only store device IDs in /run/udev/links, and when
creating/removing device node symlink, we create sd_device object
corresponds to the IDs and read device node and priority from the
object. That requires parsing uevent and udev database files.

This makes link_find_prioritized() get the most prioritzed device node
without parsing the files.

Yu Watanabe bdb492b2ed udev: do not remove control socket on exit 
As we usually do, remove old unix socket before bind.

Note that systemd-udevd-control.socket has `RemoveOnStop=yes`.
So, it is not necessary to be removed when the service exits.

Replaces #20584 and #20588.

Yu Watanabe 56fdc16da8 sd-netlink: drop sd_genl_family_t and introduce GenericNetlinkFamily 
Kernel manages each genl family by its name, e.g. "nlctrl" or WG_GENL_NAME,
and its ID (used for nlmsg_type) is determined dynamically when the
corresponding module is loaded.

This commit makes sd-netlink follow the same way; now, sd_genl_family_t
is dropped, and sd_genl_message_new() takes a genl family name. Each
genl family is resolved when it is used first time, and its information
is stored in GenericNetlinkFamily.

Yu Watanabe 9270ec60bc sd-netlink: drop genl type system indexed by command 
All type systems of currently supported genl families do not depend on

Note that type system for genl ethtool depends on commands. Let's
reintroduce a mechanism to support the deps when we support ethtool on
netlink.
