a2cc708a88 network: amend SendOption= to take a c-escaped string

864edb39cf network: rename SendOptions= to SendOption= 
The name with plural made more sense where multiple options could be specified
in one line. After changes in the pull request, this option only accepts one
value, so from users' POV it should be singular.

(The field in the data structure remains plural, because it actually stores
multiple values.)

337b733449 man: split out description of Conditions and Assert to new section 
We slowly added many many conditions over the years, and the text became
very hard to read, because all the terms were squished in one <termitem>.
This rearragnes the text into a new subsection, with minimal grammar changes
and removal of repetitions.

adc09af234 pam_systemd: Forward systemd.runtime_max_sec setting to session scope 
Allow earlier PAM modules to set `systemd.runtime_max_sec`. If they do,
parse it and set it as the `RuntimeMaxUSec=` property of the session
scope, to limit the maximum lifetime of the session. This could be
useful for time-limiting login sessions, for example.

9ed7de605d scope: Support RuntimeMaxSec= directive in scope units 
Just as `RuntimeMaxSec=` is supported for service units, add support for
it to scope units. This will gracefully kill a scope after the timeout
expires from the moment the scope enters the running state.

This could be used for time-limited login sessions, for example.

4801d8afe2 udev: introduce CONST key name 
Currently, there is no way to match against system-wide constants, such
as architecture or virtualization type, without forking helper binaries.
That potentially results in a huge number of spawned processes which
output always the same answer.

This patch introduces a special CONST keyword which takes a hard-coded
string as its key and returns a value assigned to that key. Currently
implemented are CONST{arch} and CONST{virt}, which can be used to match
against the system's architecture and virtualization type.

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.
