Zbigniew Jędrzejewski-Szmek 5f3b5f190f networkd: change SendRelease default to true
Now that we don't drop DHCP config on restart, this seems appropriate.

Zbigniew Jędrzejewski-Szmek 800603524a networkd: drop DHCPv4 config on stop, keep on restart, by default
This partially reverts 95355a281c.

It seems that other parts of link_stop_clients() should be skipped
when restarting, but I don't know enough about those other clients to have
an opinion if it is better to stop&start them on restart or not.
Anyway, that can be done in later patches now that the support for restarts
is there.

Fixes #13625.

Siddharth Chandrasekara afe42aef39 dhcp4: make IPServiceType configurable
IPServiceType set to CS6 (network control) causes problems on some old
network setups that continue to interpret the field as IP TOS.

Make DHCP work on such networks by allowing this field to be set to
CS4 (Realtime) instead, as this maps to IPTOS_LOWDELAY.
